VIruses wont install on ur PC but them selves....u can even download it and as long as u not click on .exe file it wont harm ur pc....by the way....i figured it out...if youall HAVE NORTON ANTIVIRUS OR ANY KIND OF SOFTWARE like NORTON...u dont really need NORTON..but u do if youstupid enough to click on the file .exe that u dont no..ANTIVIRUS software slows ur pc up to 10%.. u have to have some kind of Firewall i reccomend HARDWARE firewall but also ZOne Alarm Pro, Outpost firewall pro for more advanced users ad Sygate Personal Firwall..any firewall will be great as long as it blocks ur PORTS...go test ur self if yousecure
http://scan.sygate.com and run TESTS......and i do not recommend UNINSTALL ANTIVIRUS SOFTWARES for Beginners in PC stuff..but i do reccomend for people that know not to click on .exe file if ya dont no what it is, u cant uninstall it and u will c the differences..get a Trojan Remover and thats basically it
