HELP!! I keep getting this error and it freezes my computer up for a few seconds and then my taskbar..........

You def. have spyware/virus. First thing is to turn off system restore (right click my computer icon, properties) Next download or at least have 2 or 3 spyware cleaners.. Ad-aware - spybot --ect. Install and update the definitions. Also download ccleaner its free as well (this just cleans temp files/junk). Now restart your computer in safe mode, restart computer and when booting start tapping F8 key and choose safe mode. Then scan your computer with your utilities you just updated. This process may take several times of rebooting and scanning.
