Corrupt download problem
Everytime I use a web browser to download exe files they are corrupt and will not install. In Internet Explorer almost every exe file I try to run tells me the file was blocked due to it not having a valid digital signature.
I have tried multiple browsers, multiple websites, multiple files. I have downloaded sucessfully on another computer on the same network. I have sucessfully downloaded rar and zip files, torrents and transfered over MSN. The browsers work fine, everything else about the internet works fine.
I have run several memory tests and a hard drive diagnostic, all of which passed.
If anyone has any ideas, they would be much appreciated.
