Hello all,
I have been experiencing some issues regarding CPU usage (using Windows XP Service Pack 3). Whenever I open a program (any program), it instantly uses 100% CPU. For instance, if I'm using Firefox (like I am now), Firefox uses 100% CPU. If I'm using VLC Media Player, VLC uses 100% CPU. However, each time I open the Task Manager, it "reduces" from 100% CPU usage until I close it again.
I had scoured Google for some kind of solution. The only thing that remotely sounded like my problem was the igfxupdate.exe trojan that seemed to cause symptoms similar to mine. However, no such executable exists on my computer. In addition, Malwarebytes, Emsisoft Anti-Malware, and SuperAntispyware have all scanned my computer and deemed it clean.
I also use Comodo as my firewall and Avast as an antivirus. I know that they sometimes are in conflict with each other, so I have made both exceptions in each program.
Any help would be greatly appreciated! Thank you so much for your time!
