Don't know why your computer is hanging, but something like this might be the cause. But there are many possible causes.

Malware that returns after being found and fixed/deleted has infected your registry (startup), so it will return when you reboot.

To clean such stuff out:

Update your AVG and Spybot (and any other spyware protection you may be using).

Turn off system restore (right click My Computer, choose Properties, then System Restore tab) and restart in safe mode (F8 while restarting).

Run full-system scans, spyware and antivirus.

Restart your computer. Turn system restore back on.

It may be useful to clean your registry, too, after cleanup. I use Ccleaner (free; "issues" on its menu--accept the offer to backup the registry changes just in case, although I have had no problems using it).

This AV has the best detection and is GREAT. To the guy at the top, my Dad installed F-Secure on his relaively new PC, and it slowed it down to a slow crawl. ^_^
