Original Title: My computer can't find publishers for downloads.
Oops... I put it in the wrong category :(... Sorry.
I'm not sure if the title is too clear... Sorry if I mislead you.
But I am running a fairly new computer, with Windows XP SP3. Whenever I try to download something, it will say "The publisher could not be verified". In the help page, it says that the software is probably not official, or something similar. This happens with EVERY download, though. Even when I went to download Microsoft Security Essentials off the official site. Help?
