(My OS is Windows Vista BTW)
About a week ago I got this (http://blog.yoocare.com/wp-content/uploads/2013/02/fbi-cybercrime-division-virus.png
) virus. It would lock my screen every time I got on my computer. So, I opened in safemode, and then did a system restore. This fixed that problem, and my computer is pretty much usable since then. It's a little bit slower browsing the internet, but that's all. Well, almost.
I can't download anything. Pictures, software, chrome extensions, whatever. When I try, it says "Failed - Virus scan failed." I have tried opening in safemode with networking and downloading, but that didn't work. I tried to do what this (http://answers.yahoo.com/question/index?qid=20100910173344AA1wsXS) guy suggested, but the box labeled "Use a proxy server for LAN" was already unchecked. I have also uninstalled and reinstalled google chrome (which, now that I think of it, I was able to successfully download from internet explorer. Although I have already tried downloading AV software from IE). Any ideas?
