As I sit at my computer, going about my usual business of browsing the net in Firefox, my CPU Usage spikes all of a sudden. This is not associated with any webpage in particular or any time in particular. Firefox will start eating about 50% of my CPU usage. Nothing will stop that save killing the process, so I do that. However, that usage then immediately jumps over to another program. Usually it only hops onto one or two other programs before it finally disappears. No error messages, no blue screens, just high CPU usage.
What prompts me to come over here is my most recent dance with this thing in which it would not disappear through any amount of process kills. Explorer.exe started getting the 50% usage, and I killed that, and restarted it using the Run command, and it would come right back with 50% usage. I tried to restart, and the 50% usage appeared in a number of processes that had to be killed before the computer would finally shut down.
This used to be a problem associated with Magic Workstation's Play module, which is a program for playing a card game over the internet. However, it has now crept into other programs. I'm in the process of preparing my system to properly post a HijackThis log, but I wondered if this problem might have appeared in the past and if it wasn't a malware issue. So, if it's familiar to someone, please let me know. Otherwise, the scans continue, which is probably a good thing anyway.
