When the antivirus trial in your new laptop expires, you’re confronted with a selection. You’ll be able to pony up for a paid subscription, go with out safety (dangerous concept!), or change to a free antivirus instrument like Bitdefender Free Antivirus for Home windows. This app provides you a lot of the spectacular malware-fighting energy discovered within the firm’s industrial antivirus however with out the wealth of bonus options. It’s value a glance when you want high-powered antivirus safety on the lowest attainable worth. For that very same no-price, nevertheless, Avast One Important protects all fashionable platforms, not simply Home windows, and provides firewall, community inspector, and different bonuses. AVG AntiVirus has a firewall, too, plus many useful safety features. These two are our Editors’ Alternative picks totally free antivirus.
Putting in Bitdefender Free
Getting Bitdefender Free working in your system is fast and simple. You want to join a Bitdefender Central account to activate the antivirus (or register if you have already got one). When you’ve activated your free subscription, you may set up safety on as much as three Home windows gadgets, a considerably odd limitation. Because it’s free, you would spin up one other account on a special electronic mail handle to guard extra PCs. Not like Bitdefender’s paid safety apps, macOS, Android, and iOS gadgets needn’t apply.

After set up, the antivirus gives a Machine Evaluation, which features a fast scan for malware and objects left over from previous infestations. I skipped the evaluation for testing functions. It’s additionally an choice to run it within the background when you begin utilizing the app.
Like different members of the Bitdefender product line, the free version defaults to displaying a safety dashboard with a left-rail menu that provides direct entry to the app’s options. Safety suggestions occupy the highest of the window, with a half-dozen fast motion icons beneath: Fast Scan, System Scan, Vulnerability Scan, VPN, and SafePay, plus a button to alter which options present up as fast actions.
Of the fast actions, solely Fast Scan, System Scan, and VPN are enabled. The choice to swap in numerous fast scan options isn’t useful within the free version, as all the opposite choices are locked.

It could appear logical for this free antivirus to show the identical options as Bitdefender Antivirus Plus, simply locking away premium-only elements. Nonetheless, once you dig into the Safety, Privateness, and Utilities pages, you discover that the free antivirus is extra like a locked-down model of the Bitdefender Web Safety suite.
The Safety web page in all three apps contains Antivirus, Superior Risk Protection, and On-line Risk Prevention. All of those are enabled within the free version. Vulnerability Scan and Ransomware Remediation additionally seem in all three, however the free version locks them away. Lastly, Cryptomining Safety, Firewall, and Antispam, additionally locked within the free version, don’t seem within the for-pay antivirus—solely within the suite.

In the event you’re not paying on your antivirus, all the things however VPN on the Privateness web page is locked, together with Safepay (a hardened browser for monetary transactions), Video & Audio Safety, Anti-tracker, and Parental Management. The parental and video options merely don’t seem within the for-pay antivirus, although it provides a trial of Bitdefender Password Supervisor. In fact, within the full safety suite, all these options are current and lively.
The whole safety suite presents 5 objects on its Utilities web page: Decryption Instruments, Anti-Theft, OneClick Optimizer, Profiles, and Information Safety (a easy file shredder). All 5 are on view within the interface in free antivirus, reviewed right here, and all however Decryption Instruments are locked. Unusually, the for-pay antivirus doesn’t embody Decryption Instruments. Its Utilities web page solely shows Profiles and Information Safety.

Getting Began With Bitdefender Free
You must run a full scan proper after set up to root out any malware that infested the system earlier than you put in this antivirus. On the first full scan, Bitdefender warns that “as a consequence of its complexity, it’d take some time to finish” however that subsequent scans ought to go way more shortly. Certainly, once I final examined this antivirus, that preliminary scan took a phenomenally very long time. This time, the preliminary full scan completed in an hour and 27 minutes, a bit sooner than the present common of 1 hour and 53 minutes.
(Credit score: Bitdefender/PCMag)
As promised, the repeat scan was a lot sooner, ending in 6.5 minutes, a 93% enchancment. UltraAV edged out that enchancment proportion, going from about 42 minutes to lower than three. K7 Antivirus Premium and Development Micro lower the repeat scan time by about 97%.
In principle, real-time safety ought to deal with any malware issues after the complete scan. Nonetheless, for an additional layer of safety, you may schedule a day by day, weekly, or month-to-month scan, or set the antivirus to scan at each system startup.
(Credit score: Bitdefender/PCMag)
The free version nonetheless doesn’t allow you to use the Rescue Setting. This premium-only function reboots the pc right into a non-Home windows platform appropriate for eradicating even probably the most persistent malware. In the event you dig into the Superior web page of antivirus settings, you’ll discover that all the things is locked in opposition to modifications besides top-level on-off management of the real-time antivirus defend.
Close to-Excellent Lab Outcomes
Whereas Bitdefender Free does not embody each function of the industrial version, its core antivirus engine is identical as what the impartial labs take a look at. The labs make it clear that their outcomes are solely assured for the exact program they examined. Nonetheless, it’s value wanting on the wonderful scores the industrial version earned.
It is Surprisingly Straightforward to Be Extra Safe On-line
Three of the 4 labs I observe embody Bitdefender of their newest studies. Within the three-part take a look at commonly reported by AV-Take a look at Institute, antivirus packages can earn as much as six factors every for efficient safety, low influence on efficiency, and few usability issues (which means false positives). Bitdefender routinely earns an ideal 18 factors on this lab’s newest take a look at, nevertheless it misplaced a half level within the newest efficiency take a look at. Its rating of 17.5 nonetheless deserves the designation Prime Product.
All of the examined antiviruses reached at the least 17.5 on this take a look at. Greater than half scored an ideal 18, amongst them Avast, Avira Free Safety, and ESET NOD32 Antivirus.
The researchers at AV-Comparatives carry out many checks; I observe three of them. Antiviruses that go a take a look at earn Commonplace certification, whereas those who go considerably past the minimal passing grade obtain Superior and even Superior+ certification. Bitdefender took Superior+ in two of the most recent three checks, as soon as once more falling barely behind in efficiency, receiving an Superior ranking. Avast Free Antivirus, AVG, and ESET took Superior+ in all three checks.
The checks carried out by the consultants at MRG-Effitas are a bit completely different from the remainder. An app wants an ideal rating to go the lab’s banking Trojans. Something much less counts as a failure. One other take a look at utilizing all kinds of malware gives two passing ranges. If a safety app blocks each malware set up try, it passes at Stage 1. If some malware will get by way of however is eradicated inside 24 hours, that earns Stage 2. The rest is a failure.
Solely Bitdefender, Microsoft, and Norton AntiVirus Plus earned Stage 1 within the newest run of this take a look at; all however one of many others got here in at Stage 2. All however one of many antivirus instruments handed the banking-specific take a look at, Bitdefender amongst them. In each instances, Development Micro Antivirus+ Safety failed.
SE Labs makes an attempt to simulate the true world of malware as intently as attainable for testing functions, utilizing a seize/replay system to current every antivirus with a real-world Net-based assault. This lab’s certification comes at 5 ranges: AAA, AA, A, B, and C. Bitdefender has reached AAA certification prior to now, nevertheless it hasn’t been included on this lab’s current checks.
I’ve constructed an algorithm that maps all of the take a look at outcomes onto a 10-point scale and returns an mixture lab rating for each antivirus that has outcomes from at the least two labs. Bitdefender has reached an ideal 10-point mixture rating prior to now; at current, it owns a good rating of 9.7 factors, based mostly on outcomes from three labs. Of antivirus instruments examined by three labs, solely ESET scored greater, with 9.9 factors. Avast, Microsoft Defender Antivirus, and Norton turned in outcomes for all 4 labs, with Avast’s 9.9-point rating on the prime.
Blended Malware Safety Take a look at Scores
Even when lab outcomes are plentiful, I all the time run my very own hands-on testing simply to get a really feel for the way a program handles malware. If I don’t get sufficient knowledge from the labs, my hands-on malware safety take a look at is the one manner I can charge antivirus accuracy. On this case, the labs have already made it clear that Bitdefender’s know-how is top-notch.
My hands-on malware safety take a look at begins once I open a folder containing real-world malware samples I’ve collected and punctiliously analyzed. In lots of instances, the tiny file entry required to get every file’s identify and properties is sufficient to set off on-access scanning. If that doesn’t get the antivirus utility’s consideration, I copy the recordsdata to a brand new folder. Sometimes, I encounter a instrument corresponding to Guardio that solely scans recordsdata at obtain. And, in fact, some real-time scanning methods don’t kick in till you attempt to launch the file.
I observed that Bitdefender shortly set to work once I opened the malware folder. A easy “Disinfection in progress” notification appeared and remained for about quarter-hour whereas samples steadily disappeared from the folder. When it completed, it reported its success. Easy.
Bitdefender knocked out 73% of the samples on sight, together with all of the ransomware samples. That’s moderately low. Aura, Norton, and UltraAV worn out greater than 90% on sight, and ZoneAlarm PRO Antivirus + Firewall NextGen eradicated each single pattern at this stage.
Primarily based on notes from a previous overview, I attempted one other method to get the eye of the real-time antivirus. For every pattern that was not worn out on sight, I logged in to on-line storage and downloaded that very same pattern. However nope—this didn’t set off any further detections.
(Credit score: Bitdefender/PCMag)
To finish the malware safety take a look at, I launched the samples that Bitdefender didn’t eradicate on sight. A technique or one other, it detected 85% of the samples and scored 8.2 of 10 attainable factors.
Solely a few apps examined with this pattern set scored decrease. Avast, AVG, Norton, and UltraAV prime the listing, with 99% detection and 9.9 factors. Norton fills out its line of nines with 99% in my malicious URL blocking take a look at. Bitdefender’s rating isn’t nice, however when my outcomes don’t jibe with these of the impartial testing labs, I give the testing labs considerably extra weight.
When Bitdefender defends in opposition to a malware assault, it pops up a small notification with an choice to study extra about what occurred. In lots of instances, the accessible data contains an assault timeline that reveals simply how the malware bought onto your system and the way far it bought earlier than Bitdefender nabbed it. It additionally contains an “different end result” monitor, driving residence the purpose that, with out Bitdefender, the assault would have succeeded.

After I gather and curate a brand new set of malware samples for testing, I intentionally draw from samples which are just a few months previous in order to not drawback the primary antiviruses examined with the brand new assortment. I take advantage of the identical samples for as much as a 12 months as a result of it takes quite a lot of effort and time to arrange a brand new set of real-world malware.
For a view of how every antivirus handles probably the most present threats, I take advantage of a totally completely different take a look at. This take a look at begins with a feed of latest discoveries generously equipped by MRG-Effitas, usually no various days previous. Every antivirus will get two probabilities to forestall malware from being downloaded from these URLs. It will probably block all entry to the URL for full credit score, or it may possibly eradicate the malware payload throughout or after obtain, additionally for full credit score. What I don’t need to see is a verified bug downloaded with none defensive motion from the antivirus.
(Credit score: Bitdefender/PCMag)
Bitdefender blocks entry to nasty URLs beneath the browser stage, so it does not have to put in a browser extension. That functionality blocked about two-thirds of the malware-hosting URLs. It worn out roughly one other quarter earlier than the obtain may end, for a rating of 92% safety.
Bitdefender’s scores on this take a look at have various wildly. Final time round, it reached an ideal 100% safety rating, however the time earlier than that, it solely bought 81%. Avira, Guardio, Sophos House Premium, and Development Micro earned excellent scores of their newest cases of this take a look at.
Glorious Phishing Detection
Probably the most excellent malware-detection system on this planet cannot enable you to when you fall for a phishing rip-off and provides away your valuable login credentials. Phishing web sites masquerade as banks, on-line retailers, and even courting websites, and so they do their finest to entice you with an ideal reproduction of the particular login web page. Once you enter your credentials on the faux web page, the fraudsters instantly personal your account. Say goodbye to your financial institution stability or your sport avatar’s hoard of in-game gold. These fakes get caught and blacklisted shortly sufficient, however their homeowners simply scoop up their winnings and transfer on.
I scrape phishing URLs from numerous reporting websites to check how nicely an app retains its customers protected from this type of fraud. For testing, I gather verified phishing frauds, together with URLs so new that they have not been analyzed and verified. I run the take a look at concurrently on the antivirus beneath testing and on cases of Chrome, Edge, and Firefox, counting on the phishing safety constructed into the three browsers.
(Credit score: Bitdefender/PCMag)
I launch the URL in all 4 browsers for every suspected fraud and document the outcomes. If any of the 4 cannot load the URL, I discard it. If the web page does not actively try to seize login credentials for a safe web site, I discard it. After checking a number of hundred attainable fraudulent URLs, I run the numbers.
When Bitdefender detects a phishing web page, it diverts the browser to a protected warning web page, simply because it does when it finds a harmful web page. The warning web page gives a quick clarification and permits a daring (or silly) consumer to disregard the chance and go to the web page regardless. In testing, I discovered that it recognized most as Phishing pages, although some bought flagged as Harmful, Fraudulent, or Suspicious.
As with the malicious URL blocking take a look at, Bitdefender’s scores on this take a look at typically hover at or close to 100%. This time round, it managed 99%. It was a nasty day for browsers, although, with Chrome lagging Bitdefender by 39 proportion factors and Edge falling 58 factors behind.
Bitdefender’s 99% is sweet, however an ideal 100% is even higher. Avira, Guardio, McAfee AntiVirus Plus, and Development Micro all reached 100% detection, as did the phishing-centric Norton Genie. NordVPN Plus and Surfshark One, each with a VPN emphasis, additionally joined the 100% winners’ circle.
Efficient Ransomware Recognition
I discussed earlier that Ransomware Remediation is without doubt one of the many premium-only options which are out of attain totally free customers. You may assume meaning the free version doesn’t shield in opposition to ransomware, however the truth is, the behavior-based Superior Risk Protection fends off ransomware fairly successfully.
To check Bitdefender’s ransomware protection, I rolled again the take a look at digital machine to a snapshot simply after the antivirus set up. I shortly turned off Bitdefender Protect, the principle real-time safety part. After slicing all connections between the take a look at digital machine and the web, I attempted launching a group of real-world ransomware assaults.
Two of the samples work on the disk stage, not the file stage. Superior Risk Protection didn’t detect these, as they operate by crashing the system and taking on on reboot. Of the dozen file-encrypting ransomware samples, Bitdefender’s Superior Risk Protection detected 11 and utterly prevented their nefarious actions.
(Credit score: Bitdefender/PCMag)
As for the remaining one, it slipped previous Superior Risk Protection solely. Luckily, it wasn’t as aggressive as many, solely encrypting just a few dozen recordsdata.
In principle, the premium Ransomware Remediation function might need helped with at the least a type of two. Nonetheless, once I repeated the take a look at utilizing Bitdefender Antivirus Plus, I didn’t see any distinction, and Ransomware Remediation didn’t kick in.
(Credit score: Bitdefender/PCMag)
I ought to point out yet another ransomware-related function, the one titled Decryption Instruments. This one is solely pointless. Choose it, and also you’ll see instruments to decrypt recordsdata encrypted by three identified ransomware varieties, dated 2018, 2020, and 2021. You’re a lot better off visiting Bitdefender’s newest ransomware file decryption instruments on-line. The net assortment cures many extra assaults and newer ones, all at no cost.
What’s Not in Bitdefender Free?
I’ve described all the things Bitdefender Free does, however the function listing of the complete, premium Bitdefender Antivirus goes far past this. Please learn my overview for all the main points on what you get by paying for the complete version. Amongst different issues, paying clients get the Safepay safety system to forestall interference with on-line monetary transactions, an Anti-Tracker instrument on your browsers, a safe deletion File Shredder, and ransomware remediation in case ransomware damages some recordsdata earlier than being defeated.
You’ll discover a number of different options locked away within the free version however not even seen within the for-pay antivirus. Anti-theft, Antispam, Decryption Instruments, Firewall, OneClick Optimizer, Parental Management, and Video & Audio Safety all present up locked in Bitdefender Antivirus Free however don’t seem as accessible options until you improve to Bitdefender Web Safety.
In a reversal from earlier variations, the Bitdefender VPN part is now accessible within the free antivirus. However simply as with all Bitdefender apps beneath the extent of Bitdefender Premium Safety, you get a seven-day trial of the complete VPN, which powers right down to a restricted free model when the trial is over.
Verdict: Succesful Primary Safety
Bitdefender Antivirus Free for Home windows lacks the superior options that make its for-pay sibling nearly a set. Nonetheless, it does comprise a lot of the identical core safety in opposition to malware, malicious web sites, and fraudulent websites. Additionally free, Avast One Important protects Home windows, macOS, Android, and iOS gadgets. It features a firewall, a bandwidth-limited VPN, and numerous privacy-protection options, whereas AVG AntiVirus Free brings a firewall and helpful bonus options to the occasion. These two are our Editors’ Alternative winners totally free antivirus, although Bitdefender can also be excellent.
