I have a problem PC boots normally until it gets to the desktop then it restarts. This happens every time. PC worked fine before this problem, but 2 days ago "Opera.exe" file went missing, so I had to reinstall Opera. Also, for the past few months, when shutting down my PC while there is some program still running, it shows a "Memory referenced..." error for Winamp or Adobe (or some similar error, I can't check it right now because i can only get pc to boot in safe mode without restarting). I tried scanning the hard drive with Avira's and Malwarebyte's programs, there was some malware and it was removed, but the problem persists. Any tips?
