most virus are spread through IE. IE is not a safe browser. you should use a more secure browser to protect your PC from virus.
i recommand you to use firefox with Google toolbar. firefox can block any any popup and disable any virus and adware, spyware on webpage, so, firefox is much safer than IE browser. as you know, most of virus spread throught internet and webpage.
besides, firefox is much smaller than IE, so it run faster than IE.

It’s the same reason that a prostitute gets regular STD checkups, even though she requires the man wear a condom.
I know, it’s not the most flattering or euphemistic answer, but hopefully you get my point.

I use Norton too, but it’s not enough. You still have got to get rid of adwares and spywares from invading your PC. So I use Lavasoft Ad-Aware SE Professional to get rid of my adwares & spywares. Adwares & spywares are a nuisance because they tend to dwell in your system for their designed ulterior motives. The pinch or hijack your password of ID’s, login name, etc. They also slow down your system considerably.

NO anti-virus or anti-spyware can ever be relied upon to give 100% protection. None of them do, free or paid. Most only detect about 85 to 95% of all KNOWN viruses. When a brand new virus is released, NO signature-based anti-virus will detect it for several hours up to several days. And over 1200 new variants of viruses and other malware are created by the “black-hats” each and every day.
Think of it as a second-opinion, like a real world doctor. And remember…..
