stll no luck!
I did the command prompt again and it still says
Volume in Drive C is __________
Volume Serial Number is __________
But what I didn't notice before is that is also says that the file cannot be found underneath those lines.
I read the post by Griff and followed all the instructions. I have also re-installed AVG.
Still completely unable to download anything - IE still showing every attempted download as unsafe and Mozilla downloads still just dissapearing.
Interestingly, the second two online scanners you recommended downloaded on IE without a problem... The Windows Live OneCare Safety Scanner still wont download (says msert.exe contained a virus and was deleted on IE, dissappears on Mozilla). I also couldn't download anything else - I transferred it with a flash stick.
