Really odd.. I tried to open a zip file (didnt have a virus) and it said it was corrupt so i re-downloaded it. The same error happened again, so i checked other zip files that i know work and it said the same. i re-booted and it was fine but messenger was square block in the taskbar. There was also another messenger icon, but i always seem to get 2 at startup. Could this be a virus? It all seems fine now.. but it was so odd.
