I'm a computer guy and have come across a second occurrence of this problem.
The computer is very sluggish in responding.
The %temp% folders fills with hundreds of 3 and 4 character folders... takes hours and hours to delete them all. The computer also starts creating fla*.tmp files as well. If you remove the computer from the network the folder creation stops. If you then reboot into safe mode with networking and join a network you can browse without issue. If you simply reboot the computer, without removing it from a network, the process WILL continue in safe mode.
This is a Windows 7 computer.
Process Explorer doesn't really help a lot since things are bouncing around so much. DVDUPGRD.EXE seems pretty active. Searching for DVDUPGRD.EXE on the computer yields 3 files with a creation year of 2009.
The first occurrence of this, back in early Nov of 2014, resulted in wiping the drive and starting over.
