The W32 error is actually a computer virus running slowly in the background of the computer. I just finish reading thru the posts in this topic. To avoid having this problem again, there are a few solutions that I can think of. Firstly is to update any virus definitions and scan the overall computer. Secondly, is to clear all your Internet Explorer or Mozilla or browser cache, cookies, and all. Thirdly, some of you mention system restore or using recovery CD - it may work and it may not work depending on the strength of the bug and what defects it has done to the computer. Dont simply do something you know you can fix but it actually does something else more harmful to the computer. Fourthly, the Microsoft patch may work for some people and may not be for all - the patches are for several versions of operating systems and beware to scan the patches first for virus as of coz, I dont trust any downloadings from the global Internet as we dont know the real source of the websites. So just be prepare and try to backup your information first before the worst happens. The W32 bug error is quite common these days and it spreads quite fast. How it comes into our computers is something I am still not sure. This is all I can share at the moment.
