My Kapersky Internet Security works fine.It didn't crashed my computer. It has blocked  the MSSQL.worm.Helkern! from intruding into my computer many times. It also detected  'Trojan.Generic' when I tried to install an add-on to my Internet Explorer. It also blocked adwares and includes a firewall and many other features. I also use AVG Anti Virus. It is also good. It also detected and quarrantined many viruses before I started using Kapersky. To avoid conflicts you can always inactivate one on the anti virus program realtime scanning .... So I think there is no one effective anti virus program. . . I would also suggest installing McAfee SiteAdvisor. It is not an anti virus program but an add-on for Internet Explorer. It turns red if you go to a site that has virus, adwares, malwares etc. And you can check with it before visiting a website. If it does not know about that site it will let you know too. ..This is prevention rather than cure. I am using this combination. . . I also use Kapersky firewall instead of Windows firewall.

It is great and it also uses less memory than Norton. I stopped using Norton and Use AVG. It's a good choice. The virus signatures are updated daily so you will be protected well. I've been using the free version for about a year now and am virus free.\n\nUninstall Norton Antivirus and reboot the PC before loading AVG. \n\nI also use Microsofts free spyware preventer. It is in beta. Load this program, too.

What version of Norton are you using? are you using 2005? If yes, they you dont have to anything. It has an in built Anti spyware, which is heck lot better than Windows Defender. I would not personally recommend it to u coz it will make ur compture pretty much slow. Also, they may have some conflict with each, which may coz hard drive Crash, slow running comps, weird behaviors etc.

Hi. Sometimes the scans exaggerate a bit. Search for ' adaware se', ' spybot ', and ' avg free' . They seem to work well and also seem safe.

These 3 will protect. I use all 3. They are all free. And use no system resources.\n\nSpywareBlaster\nhttp://www.javacoolsoftware.com/spywareblaster.html\n\nIE-Spyad\nhttp://www.bleepingcomputer.com/forums/index.php?showtutorial=53\n\nMVP Hosts File\nhttp://www.mvps.org/winhelp2002/hosts.htm

AVG works best in tandem with programs like Spybot Search & Destroy and Ad-Aware, and one other free antivirus of your choice (like say Mcafee Stinger).\nTrusting your system to only one antivirus or trojan/spyware detector is just suicidal. No ONE program will detect everything.\nPS - Norton is the best....at slowing your system down, hogging system resources...screwing up if you try to uninstall it...taking forever to do full system scans...yup...Norton is the best at SUCKING LARGE.

I've never used it, but PCWorld.com gives Bitdefender 9 a very good rating.  They even say it's the best antivirus.  Read the link below.

My brother installed it on his computer and after that everything ran incredibly slowly, so slow you'd almost think the computer had frozen.\n\nI managed to get round it in a long winded way so that now it's just the start-up which is slow.\n\nAfter this experience I'd be tempted to use Norton, eTrust, Panda or some other anti-virus program.

Spybot search and destroy.....for other malware try ad-aware SE...these are both free. For viruses I have tried Norton and McCafrey, but I hated them. I use AVG 7.1...It is free and works like a charm. Windows defender is not very good. I have XP SP2 and use the three I listed above earlier. Good Luck!!

zone alarm is a good firewall..thats what many people say...norton anti virus is a good option but it slows down the pc...even u can choose panda...if u want a free anti virus,go for avg or avast...

You don't want to have it stop blocking attacks. If you do, you'll compromise your system. Avast is there for a reason. Use it.

adaware + spybot + ms windows defender beta\n\nuse them all, they pick up different things
