What Free Antivirus Do You Install On Windows? 896

Posted by timothy
from the is-clamav-no-longer-good? dept.
Techman83 writes "After years of changing between AVG Free + Avast, it's coming time to find a new free alternative for friends/relatives who run Windows. AVG and Avast have been quite good, but are starting to bloat out in size, and also becoming very misleading. Avast recently auto updated from 4.8 to 5 and now requires you to register (even for the free version) and both are making it harder to actually find the free version. Is this the end of reasonable free antivirus, or is there another product I can entrust to keep the 'my computer's doing weird things' calls to a minimum?"

    I should think "friends/relatives who run Windows" would be exactly the type to appreciate the convenience of a low-impact reliable AV package, which means they may have to pay a few bucks. It's fine to play FOS yourself or with trivial office or audio stuff, and I do it myself. But I still give ESET a few shekels/year for each windows PC in my house. It just makes sense to me.

    I used Avast 4.8 for about a month. Then they upgraded to 5.0. Didn't care about the registration, but everything else just irked me to no end. On the other hand, MSE has every advantage you listed, plus no registration, and the updates are gathered through Windows Update, so you don't have yet another service updating itself.

    Oh, and the quick scan takes about 3 minutes.

    At work (a university) the central IT has chosen to license Sophos. It is, well, crap to put it mildly and takes up amazing amounts of resources. So, instead we use Security Essentials on many systems. Works well, it has successfully stopped viruses that users have tried to get. Pretty light on resources over all, not the lightest weight program I've seen but up there.

    Best one for free I've seen. Personally ESET NOD32 is my favourite and what I license for home, but if the price requirement is $0, then MSE is what I use.

Pretty much the only packages that have better detection rates is payware, and this beats the payware in false positives. Also, the interface is easy to understand, and it stays out of the way.

    I mean I could write a system tray app that's a "virus checker". and always tells you your system's ok... haha

    When I am asked this question my answer is always this. None. I think antivirus is more trouble than it is worth. First any new viruses will be undetected, second the pain of actually running anti virus outweighs any marginal benefit received from it.

    Of course this answer immediately creates a follow up question... Well then what do you do?

    Actually, thanks for the posting because you've put the seed of an idea into my head.

    I'm a Linux & security consultant at my place of work & therefore get a lot of freedom in running what I want to on my laptop. I've been using OpenOffice (on Linux and XP) at home for a while now, I finally managed to ditch Office 2003, specifically Outlook, when I recently got rid of the last phone dependant on ActiveSync and Outlook for synching contacts.

    The standard at work is XP and Office 2003, having messed about with Thunderbird & Sunbird recently, I'm pretty sure I can manage on those for email & calendaring at work - really the last issue to resolve is how to deal with Microsoft domain resources & cope with forced password changes every 60 days. I was planning to look more deeply into Samba to see what that's capable of, but now you've put the VM idea in my head, specifically because I also got updraded to a dual-core Lenovo laptop a few weeks ago.

    Just because you can't be 100% safe with any given product is no reason to abandon it entirely.

    I recently reinstalled Windows, and while I've historically used Avast, I opted to go with nothing this time around. I'm tired of resource usage and slower load times for everything thanks to antivirus; I've moved my e-mail to Google Apps, so they scan my e-mails for viruses. My use of Bittorrent is extremely limited (I only have it installed because Star Trek Online's installer is available via torrent), and I never visit the seedier side of the internet. I'm behind a firewall.

    Basically I'm not going to get a virus, so I see no reason to run anti-virus software. Rather than "Can't be 100% safe, may as well not use it", my reasoning is "I'm already 99.99999% safe, so why bother".

    (Yes, I know it's still technically possible to get a virus. But the chances are extremely slim, given the way I use my computer.)

    Although it is missing an on access scan, I am not sure if that is a plus of a minus

    I could live without an on-access scan (tell your download manager to scan downloaded files), but Clamwin is completely unusable, IMHO, because it uses up much more system memory, and takes 4X as long to scan compared to the more common Free AVs.

    If you want real, free antivirus, go with MoonSecure (v2.x), which is GPL, does on-access scanning, and uses the ClamAV database. It does (momentarily) use up a lot of memory, and slow down the system, but only when first starting up, or updating definitions. Other than that, it's no more of a dog than any other free AV. Free for commercial purposes, likely to have definitions available forever, etc.

    The standard at work is XP and Office 2003, having messed about with Thunderbird & Sunbird recently, I'm pretty sure I can manage on those for email & calendaring at work

    Then either you don't use calendaring very heavy and have been using Outlook as a mere email client. I develop plugins for email clients. I freaking HATE Outlook in just about every conceivable way. If I was a sales person or a manager who gets stuck with lots of meetings and high email traffic, Outlook would be my preferred email client.

    Outlook is not an email client. Its not a calendaring application. Its a PIM, it does email as well and integrates it rather well even though its email system feels crappy and has horrible imap support (O2K7 and O2010 aren't bad for imap, too bad they ripped out the IE rendering engine). Thunderbird is an email client and its great at that. Sunbird is a calendar package, and its kind of shitty. The combination of the two is utterly ass-tastic.

    If you want calendaring just ditch sunbird and use gmail or apps for your domain. Yes you can use Sunbird with it, but unless that has changed recently, that too is a shitty experience. Probably should have kept some phones with ActiveSync exchange support though since thats about the only way to sync calendars that doesn't suck total ass.

    Its fine that you run the software you want to run, and if it works for you, thats great ... but ... If you're replacing Outlook with Thunderbird + Sunbird than you weren't really using Outlook for much more than an email client, which is probably its worst feature. Please don't go around suggesting to normal users to do the same.

    Microsoft Security Essentials [microsoft.com] is all you need for non-enterprise A/V.
    It's free, it's unobtrusive and it works very well. What's more, commercial AV vendors, like Symantec, realise what a threat it is to their business model and have published a lot of FUD about you get what you pay for - however all the benchmarks I've seen have it ranking up there with the best of them.

    The only reason to go for a commercial AV package is if you need a management and reporting console to manage a large number of computers.

    I used to think this way as well. Although, I had a virus scanner installed for scanning downloads, I did not have it actively scanning. Turns out my thinking was as flawed as yours. The problem is that with one vulnerability in your web browser or a browser plugin, malicious code can be executed and that code may run a bunch of detectable viruses. This exact problem happened to me when I was surfing the internet checking out some information on a game I was interested in. Randomly out of nowhere my computer started crawling and upon loading task manager I saw tons of processes spawning. (I shut down promptly and fixed using another computer.) After all was said and done it turned out whatever the exploit was had installed a bunch of different viruses. It was a very interesting attack that I had never expected, just as you have not.

Oh, and it's really easy to use and requires very little (if any) customizations. It just works right out of the box per se.

    One thing to be aware of with that product however. It has a feature called Smart Scan. If your server is under powered and/or you have WAN connections to other networks, disable this feature. It doesn't seem to be much use anyways. We have seen strange issues with it on though when left on.

But if it's built such a strong base of trust among people more in the know than myself, it must be worth a second look.
