Understated Ur-Drakon Nioca Posted June 8, 2012 Share Posted June 8, 2012 Alright, so here's the thing. Right now, I'm kinda unsatisfied with the anti-virus I'm using (Microsoft Security Essentials), mainly because it tends to be a massive CPU hog; enough so that it can actually bring everything else to a screeching halt until it finishes updating, passive scanning, tidying rosebushes, or whatever the heck it decides to do at the moment. I switched to MSE after Avast! thoroughly screwed my system and almost turned it into a smoldering wreck. The SW community is rather tech-saavy, and my track record at searching for things online is not great. Thus, I thought I'd ask you guys: Which anti-virus software would you recommend I use? I'm looking for something that's low maintenance, works quietly in the background without eating up a ton of resources, is effective, and is free. Any help would be greatly appreciated here.

Hatchling Cockatrice Lilith Posted June 8, 2012 Share Posted June 8, 2012 If your computer is old enough that MSE makes it chug, probably any other free antivirus with real-time protection will give you similar problems. The best advice I can give you is to turn off your antivirus, run a scan with MalwareBytes every couple of weeks, use an adblocker like Adblock Plus to avoid loading advertisements (a major source of infection on otherwise trustworthy sites), and don't visit dubious websites.

Ineffable Wingbolt Erebus the Black Posted June 8, 2012 Share Posted June 8, 2012 Yeah, I have the exact same problem as yours. I run AVG8 (and I don't want to update because I know it will become a much larger resource hog) and every time I need to scan, I have to shut everything else down or the scan will take up to 3 times longer (to scan ~800k files unabated it takes around 5 hours) and the scan can sometimes cut my internet connection. On the other hand, if I don't mind the wait I can run things on dosbox and other old machine emulators or play solitare while I'm waiting.

Easygoing Eyebeast keira Posted June 8, 2012 Share Posted June 8, 2012 What Lilith said. ABP is the way to go. Not only does it stop those questionable ad domains from infecting you, you also don't have to see the ads or wait for the ads to load. I have MSE on my Windows machines just in case, but the combination of Adblock and not visiting obvious scam sites means it has never picked up anything. Also, depending on how loose your connection is, you might want to consider disabling or firewalling stuff. I've never had any problems like that because my internet is practically impossible to deal with, but it's something to look into if dial-up (have you upgraded yet?) is a bit less NATey.

Rotghroth Rhapsody Prince of Kitties Posted June 8, 2012 Share Posted June 8, 2012 Nioca: unfortunately your "low-maintenance" antivirus does not exist, free or otherwise. Windows security is difficult, and no solutions are truly low-maintenance. When you're using the same family of OS as 90% of computer users, you're simply going to be a bigger target. Lilith's advice is generally sound, but attack vectors are many, malware is nasty, and weekly scanning can be too little too late (e.g. if you pick up a keylogger). You can get infected from a drive-by install, a PDF or Office document, a malicious or hacked website... IMO the most important rule on Windows is caution, with or without an antivirus. Don't open emails that might be spam. Don't go to websites that you're not sure are trustworthy. Don't install software you've never heard of. Don't open files from unknown sources - and be aware that antiviruses might declare them clean when they're not. Also you probably want to disable USB autorun. See here. (And if you make payments online, you might want to think about making them from a live CD such as Knoppix if possible. This will ensure that your keystrokes are not logged by any local malware. Likewise for unsafe browsing - the live CD makes it harder to get to your Windows installation.) Edit: A disclaimer... I'm a bit of a security nut and I don't use Windows much, so do take my advice with a grain of salt. Quote Link to comment Share on other sites More sharing options...
Easygoing Eyebeast Trenton. Posted June 8, 2012 Share Posted June 8, 2012 Bashing your computer with a hammer is a good way to get rid of viruses. But then again it is also a good way to get rid of it ever working again... Quote Link to comment Share on other sites More sharing options...
Understated Ur-Drakon Tyranicus Posted June 8, 2012 Share Posted June 8, 2012 As Lilith mentioned, MSE is very lightweight. If that slows down your computer, pretty much anything will. You already mentioned Avast; the other free AV staple is AVG Free, but I really wouldn't expect much better PC performance with that.

Easygoing Eyebeast Dintiradan Posted June 8, 2012 Share Posted June 8, 2012 There are ads on the Internet?? I recommend against Avast; it plays a siren when it detects something, and will probably give you a heart attack the first time you hear it. I use AVG Free on my Windows partition.

Seasoned Roamer Dire Hobbit Posted June 8, 2012 Share Posted June 8, 2012 I use MSE (with real time protection turned off). - It's the "real-time" or "active" components of antivirus software that slows things down scanning every file. Together with noscript + adblock plus, and spybot (immunization) and malwarebytes. Quote Link to comment Share on other sites More sharing options...

The closest you can get is likely an ad- or upgrade-nagging-supported free edition of a commercial package. I used to run Avira, and it was reasonably nice to handle and caught some stuff.

(I also scan with MalwareBytes too, maybe once a month, in the hopes that I have another barrier if anything gets through the anti-virus.)

Easygoing Eyebeast The Mystic Posted June 9, 2012 Share Posted June 9, 2012 I use AVG free and Norton 360. Yes, I know you're not really supposed to use more than one antivirus program, but they work pretty good together for me. The only trouble I've ever had was when I installed Norton 360; I installed it first, then had to disable it temporarily so it wouldn't prevent me from installing AVG.

Understated Ur-Drakon Nioca Posted June 11, 2012 Author Share Posted June 11, 2012 Okay, thanks, I'll look into some of this. I had forgotten about Avira; I had it before, but switched to Avast! because I had heard it was better. I recall it ran pretty well the last time I had it, and will look into it. I'll also be looking into MalwareBytes as well. Quote Link to comment Share on other sites More sharing options...
Garrulous Glaahk Tycho Maudd Posted June 15, 2012 Share Posted June 15, 2012 I run MSE myself, but I will add that the people saying to use ABP and noscript are right. I would also go into the advanced settings under my computer properties and turn on data execute protection for all programs. It's protected me more than any anti-virus program has when downloading questionable items. It'll normally stop something from running before I get a notice that the item is infected.

Garrulous Glaahk macdude22 Posted June 15, 2012 Share Posted June 15, 2012 I use Vipre on my Windows PCs, it's very lightweight and works well. We run Vipre at work as well (technically Faronics AVE but it's powered by Vipre). It's not free but with your paid subscription you get free malware removal on the off chance you pick up something. I doubt it's any more light weight than MSE however. I picked up a lifetime home site license during a black Friday sale a while back.

Rotghroth Rhapsody Prince of Kitties Posted June 15, 2012 Share Posted June 15, 2012 There are also some other routes you can go... - SandBoxie is like a UNIX chroot sandbox - it creates a fake filesystem that malware can write to, only to be deleted later. It can also block internet access, access to certain hardware, and other stuff. The free version is limited to one sandbox, and is good for browser security; the paid version lets you create sandboxes as needed, and can be used for testing applications and stuff. Pros: Currently impenetrable to the vast majority of malware. Cons: Requires a fair amount of user interaction. Also, some malware may be able to log activity and phone home from within a sandbox, depending on settings. - Host Intrusion Prevention System. The best free one I know of is Online Armor. These are aimed at experienced users; they can be a royal pain to set up, especially if you use execution control. But they're pretty light on resources, and offer better security than an antivirus if you know what you're doing... Pros: Lets you manage all kind of policies for all kinds of applications. Theoretically better security than an AV. Cons: Lots of user interaction during initial setup. Inconvenient if you compile stuff. Can break applications if you don't know what you're doing. Mistakes or lapses in attention on the user's part can result in infection, and are more likely the more paranoid the security setup! - Software Restriction policy. You run as a limited user, and only allow applications that are installed by the administrator user. See MechBGone's SRP guide. The best way to do this is with the Parental Controls on Windows Vista/7, but it's easy enough to set up on XP Pro as well. If you're using XP Home, though, then you're unfortunately out of luck. Pros: Makes almost all malware inoperable. Easy to set up, and requires almost no maintenance. Cons: Requires a limited user account. Inconvenient if you compile stuff, or run applications from your home directory. May prevent some games from working properly. DLL-based malware,or any malware that injects itself into a trusted process, will probably slip right through this security setup. ... Like I've said, all of these have their disadvantages, and IMO none of them are really adequate. Nonetheless I this helps you out. Quote Link to comment Share on other sites More sharing options...

Ineffable Wingbolt BMA Posted June 16, 2012 Share Posted June 16, 2012 I had used Kaspersky on my PC. It made everything so slow (to be fair, I only had 256MB of RAM), that I uninstall-ed it and decided not to use antiviruses. That was around four years ago. All executables on my PC are now either corrupt or infected, to the extent that I wasn't even able to re-install Windows XP until after I boot-disked from Linux and went on a massive deleting spree.

Rotghroth Rhapsody Prince of Kitties Posted June 16, 2012 Share Posted June 16, 2012 Also, a bit of advice... Never, ever assume that your security setup is working at its theoretical best. If something can go wrong, it will. (Which is why I'm now trying to track down a rootkit infection on a Windows machine that I thought was pretty well secured. It seems to be some kind of awful TDSS variant... Yay.) Quote Link to comment Share on other sites More sharing options...

I once had a virus get itself lodged in an "uninfectable" file in a "protected" system folder, and both AVG and Norton refused to believe that anything was wrong. After several unsuccessful attempts to remove it, I ended up having to do a seven-pass erasure of the entire hard drive, and start over from scratch.

Magnificent Ornk Student of Trinity Posted June 16, 2012 Share Posted June 16, 2012 I know that Mac viruses exist and that the platform isn't really invulnerable. But in fact I've been using Macs for years and never met a virus, nor have any of my students. I've installed Sophos a couple of times, because the university offered it free, and it never gave any trouble, but never actually did anything, either. My goal in installing it was mainly to avoid passing on Windows stuff, even if it wasn't hurting me. But I don't think it ever found anything at all. Oh, I expect I should probably make a point of putting anti-virus stuff on everything soon. But I'll probably have replaced several of the group machines before this really becomes important, so maybe I'll just worry about it with the new ones.

It's an older drive to begin with, so I wasn't worried too much about extra wear; and there weren't any bad sectors on the drive, I checked. And I had already spent almost a week trying everything I could think of before the overwrite, so it was done basically as a last resort. The short of it is that total erasure was the only solution that worked, with the exception of introducing the drive to the business end of a ball-peen hammer.

It's better to have some form of protection that just sits there with nothing to do, than to have no protection at all and think you're safe. I have a friend who's almost fanatically devoted to his Mac, and he's convinced himself that it's totally immune to any and all viruses, even without antivirus software. This is even after I told him that some of his favorite programs were also favorite malware targets. Quote Link to comment Share on other sites More sharing options...
Rotghroth Rhapsody Prince of Kitties Posted June 16, 2012 Share Posted June 16, 2012 I personally believe on-access antivirus software is starting to get obsolete anyway. There are too many new malware varieties for signature based detection to keep up, and heuristics are often ineffective (never mind resource-intensive). And there are less intrusive strategies of at least equal efficacy. (The one I usually think of is mandatory access control, which various UNIXes have had for ages. Windows alas is only starting on that.) Quote Link to comment Share on other sites More sharing options...
Rotghroth Rhapsody Prince of Kitties Posted June 17, 2012 Share Posted June 17, 2012 On the other hand, if you think an antivirus is the way to go, you could try Panda Cloud Antivirus. It does its heuristic stuff on Panda's servers when you're online, which should theoretically reduce the overhead on your machine. (In practice, I found that the shiny DirectX based 3D interface slowed it down considerably. Gods only know what possessed them to make their GUI over like it was some kind of toy... But if you have a nVidia or ATI graphics card with dedicated memory it shouldn't be a problem, ha ha.) And I'd better stop commenting on this thread before my pathological obsession with computer security starts showing. Quote Link to comment Share on other sites More sharing options...
