Go to www.grisoft.com and download the avg antivirus software. It is free and as good as Norton or any other antivirus software that charges you money. (it was on NBC's Today show one morning last year - that's how I learned about it)\n\nI also use spybot - search & destroy. I download lots of files etc.. and I never have problems with viruses or spyware... so this stuff works.

AVG is a very good antivirus software\nhttp://free.grisoft.com/freeweb.php/doc/2

I heard AVG is free and its really good. Its the only free one I know if you dont want to use the trial version of mcafee or norton.\n\nDownload it here: http://www.download.com/AVG-Anti-Virus-Free-Edition/3000-2239_4-10320142.html

If you want free use AVAST or AVG for Antivirus (completely free)\n\nIf you want spyware use AdAware SE or Spybot S&E (completely free)

My personal all-time favourite is AVG (http://free.grisoft.com/ ), but I've also tried other antivirus solution like Avast (http://www.avast.com/ ), and ClamWin (http://www.clamwin.com/ ). Both of them are decent free antivirus, I recommend them. Avast failed to get into my favourite because I don't really like the interface although it gives a decent results. While Clamwin failed to become my favourite merely because it doesn't have real time scanning, which is good for PC that is tight on resources (mostly because I've already too used to AVG though)\n\nNote: I have to tell you that you MUST NOT have more than one antivirus installed at the same time, if you want to try other AV product, you have to uninstall the current AV product.\n\nPS: For other answerer's information, he asks for an antivirus software and not firewall software (like the mentioned Sygate) or antispyware software (like the mentioned Spybot SD).

Nod 32  is the best , but AVG is an excellent anti virus. They do a superb free edition too.

Well... no free Anti-Virus is perfect...\n\nAvast is decent, and has alot of features but it's SLOW and detection isn't that great.\n\nAntiVir Classic offers Active Guard  but no email guard and it sometimes has false detections for trojans.\n\nAVG offers On-Demand scanning and Email but it doesn't open archives and can only select the files most likely to be infected.\n\nBitDefender is a very trusted Anti-virus and offers a free version, but it doesn't have active guard.\n\nClamWin is ok and opensourced.. but you have to set it to auto remove things, and it doesn't have active scanner unless you go to Sourceforge.net and download WinPooch to use with it.\n---\n\nPersonally I use AntiVir as my active guard and Bitdefender \n\nFree as my On-demand back up scanner...And Portableapps.com \n\nClamWin for my USB so I can take a AntiVirus with me as I go.

four good options:\n\nAVG Free, AVAST! Home Edition, AntiVir, and BitDefender Free Edition.  All provide on demand scanners;  BitDefender does not provide an always available background scanner, while the others do, making BitDefender a good complement to the others if you want a second antivirus engine that won't conflict with the first.

As two other people have pointed out, AVG is great and free.\n\nJust stay away from Symantec --it slows down your computer tremendously.

Norton Antivirus is not a free program. It's not really the best virus scanner either. You might want to try AVG, Avast!, or Active Virus Shield. \nhttp://www.activevirusshield.com/antivirus/freeav/index.adp\nhttp://free.grisoft.com/doc/2/lng/us/tpl/v5\nhttp://www.avast.com/eng/avast_4_home.html
