the one and only legit FREE antivirus for WINDOWS



  • Hi, I would really like to advertise this software product to anyone who is looking for an alternative. the guys of this company are really honest and there is no ads at all whatsoever while using this antivirus solution.
    it has anything you could ever need and more. and of course there is no bloatware at all (just some addons you can remove or choose to not install from the outset)
    i fortuitously turned to this product as a last resort and never looked back.

    i tried a lot of antivirus softwares but was about to go without any at all. found this and works smoothly and light even with old computers. have fun.

    second free and lighter choice = windows defender



  • @urfausto

    all of them are trojans

    By that logic, this one is a trojan too 😉

    @urfausto That was the last AV I ever used, and I would still use it today, if I ran XP. Unfortunately, it prevented my wife's Quickbooks from running at some point, and even whitelisting Quickbooks did not help. So at that point, Comodo went the way of all other AVs that have ever been used here.

    Although Comodo does its job according to the opinions, it is not by far the best, it is also bundleware in its free version. Tech review quote:

    "Furthermore, when installing the free edition, you need to be careful not to let the installer introduce any changes to your OS because the Comodo Antivirus will automatically change your primary search engine and browser."

    This shows me that, although perhaps valid as AV, it is not so much as reliability of the program itself

    @Catweazle I no longer have a current opinion on it, as I have not used AV in years and years.

    Currently, Win Defender is enough for me. Before, when the Defender was still not very reliable with less than 70% detection in the first versions of Win 7, I used Panda that has never let me down and that I consider one of the best. At least it is currently the only one that due to its lightness can be an alternative to the Defender in PC of few resources (~20 Mb memory use) being based on the cloud for its virus definitions with real-time update and a good heuristic.



  • @Ayespy While I understand you are clever enough to not get malware of any kind, don't ever encourage others, especially Windows users, to browse internet without antiviruses. Majority of people are too dumb when using computers, and it's the reason viruses spread when they actually were real viruses and spread by copying themselves, now it's more a defense from trojans and ransomware, which are not going to decrease if they are effectively able to infect defenseless users. The more people are able to shield themselves against malware, the better for everyone.



  • @Pathduck Agree, @urfausto don't spread illogical FUD please.

    The latest comparisons of AV test show a detection rate of 100% for Windows Defender, at the same level as the rest of the tested AVs.Therefore it is currently unnecessary to use a third party AV. A rest of risk always exists with any AV and depends largely on the user himself and an irresponsible use of the internet (illegal downloads, click on shortened links to unknown pages, open attachments in unknown emails, etc.), this can always provide an unpleasant "gift", independent of the AV you use.

    Hmmm, Comodo have turned up in the news for all the wrong reasons for too often, which shows they either don't learn from their mistakes or just don't care.

    We are used to hearing of AV having a vulnerability or two, but rare we see terms like "...contains a swathe of severe vulnerabilities..." as happened a few months ago (now fixed...hopefully).
    https://www.zdnet.com/article/comodo-antivirus-subject-to-serious-unpatched-vulnerabilities/

    Their lax attitude to certificate chain of trust is also why nearly all malware now has a valid certificate.
    Personally I feel they should have had the same treatment dished out to Symantec when they were stripped of the trust to issue certs by all the browsers, but for some reason they are allowed to continue.



  • @Dr-Flay from the same article:
    Updated: Updates to resolve the security flaws are expected to land on Monday.

    i get that there can be a lot of competition and warfare between all the products and that everyone can be subject to discredit someone else but pointing out mistakes can also lead to solve them. that said i don't aim to credit this antivirus as the best of the best and being flawless, from my experience im just saying that if i didn't find this antivirus i would stick to Windows Defender and nothing else (i'm on windows) because other products are so much freaking bullshit with fake protections or loaded with ads or whatever else privacy breakers you could think of. so what is the point of having an antivirus that does the spyware job right from the inside?
    i don't care about a flaw or two when that can get fixed with updates.

    as for now my comodo addon is substituting windows defender.



  • @iAN-CooG I also have not used any Antivirus apart from Windows Defender and Firewall for years. My long experience of solving problems on forums indicates that many are caused by antivirus sending vital files to quarantine, so I recommend not using such products.

    That IS an antivirus, so you can't say you aren't using any 🙂

    AV companies got a bit lazier in last years, they tend to include everything they don't know as "potential" or "suspect" but if you use the report forms on their site for reporting bad/false detections they usually generate better signatures to avoid the false alarms. I always found both Avast and Kaspersky being very quick to adjust their signatures when reported.
    Last week I reported 4 false alarms to Kaspersky, they promptly replied in few minutes their mistake and a couple of hours later the signatures were updated.
    Not reporting bugs and just surrendering is not useful to anyone.

    That is why he said "apart from Win Defender", which is also an excellent AV today and shure the best of the free ones.



  • @iAN-CooG yes, it is by default on windows and free. in fact this is another antivirus solution, didn't think about it because it is default with windows updates.
    this is also the lightest solution for malware protection and could easily go with just this!
    comodo for when you need more functionalities, it has all you need.

    Windows Defender also, in addition it is not recommended to use 2 AV at the same time, since when analyzing the same sensitive sites of the system, they can conflict. It is enough that one has a false positive and the other not to lose important files permanently or that one identifies the other as malware.

  • TL; DR:
    If you think Windows Defender isn't good enough, you clearly care enough about your security for it to be worth paying for a decent AV from a reputable company.


    Just my £0.02...: I have used Comodo on and off for a while and there are some things I like about it and some I absolutely hate. I love the fact that you can still make it ask the user what to do instead of only allowing auto-quarantine like many AV solutions today. I also like the fact that it works on file scanning and behaviour blocking, so it doesn't need to sniff your internet traffic (some AVs do this but implement the feature so poorly it actually lowers your security by breaking HTTPS validation). What I don't like about Comodo is some of their lax security practices that have made the news over the years, and the unnecessary bundled cruft in the installer (PrivDog, GeekBuddy, Yahoo homepage/search-hijacking etc). Yes, it can all be disabled, but it tarnishes their image somewhat. I know every free AV provider's doing it these days, but it still doesn't make it the right thing to do. I also don't like their absolutely abysmal detection-rate, high level of false-positives, and the sheer weight of the solution. It takes up masses of RAM, hard disk space, and absolutely eats my CPU, whether it's an 8 year-old Atom, or recent dual overclocked hex-core i7-8700Ks. I also find its interference breaks a lot of other software, even when you allow it in Comodo's interface, and sometimes it makes Windows a bit more unstable than it already is. It's also an extremely noisy solution, unless you tell it to automate absolutely everything, in which case I suspect a lot of the protection is lost. Unless you're a very technical person with no money, you can do better.

    Windows defender has its upsides for your computer-illiterate Gran who just wants to send an e-mail to her friends at computer class. It's built-in to the OS, is extremely simple, and its detection rate at present is great. It should also be the most stable solution as it is part of the OS itself. However, because of this, it will be the first solution to be targeted for disabling/evasion by new viruses. Its detection rate is also inconsistent, and it is rather simple, meaning that it relies more on detection and really simple behaviour rules than more sophisticated products would. It also leads to a lot of problems because it has nearly as many false positives as Comodo, and its Ransomware protection blocks lots of legitimate programs from doing what they're supposed to, including most software-installers, Libreoffice and even Microsoft's own xcopy! That said, if you're not willing to fork out for a decent AV, and you insist on using free, you may as well just use Windows Defender.

    If you think Windows Defender is insufficient for your needs, you should really care enough about your security to either use an OS that isn't targeted by as many viruses, and/or pay some money for a lightweight, effective AV solution from a trusted company with a good track record, such as F-Secure, Emsisoft, et al. £29 per year to protect a number of your devices with the base-level of protection from one of these providers is a lot cheaper than identity-theft or ransomware-payments from using a second-rate AV (or the data-harvesting crud with backdoors and unpatched-vulnerabilities, that gets bundled with its installer).



  • @jamesbeardmore yes you are right too, this is however about FREE stuff because you don't the money to afford it and windows mainly. linux i think is good even without any antivirus, but i don't know for sure.
