I have a desktop machine(Vista SP1) and laptop(XP Pro SP3), both using IE7, and Avast Antivirus. I logon to SnoWest all the time with both of them, never had any virus issues, but I take care of my computer's religiously. Been using computers for 18 years and I'm in the industry so I know I'm safe. Seems like alot of the guys on SnoWest that have had problems are running IE6, I would highly suggest updating. IE7 is not buggy like it was when it first came out.
