lol because you think a virus can cause your physical computer to fail.
No.
The only problem is on the software side. it has leftover remnants of itself that still hog cpu and memory power. Reinstall windows, your computer will be back to normal speed again.
But you probably have no idea what I'm even saying, since you thought it fried you cpu to begin with.
edit:
Not a virus or my programs woulda've blocked the process. Also I have an Intel which is kinda weird though. Intel's are suppose to be "underclocked" so I have no loving idea how it got screwed up.
Edit: Good thing I didn't have AMD or my computer probably woulda've caught fire.
again, no. its not hard for virus writers to make adjustments to their virus to evade virus detection, even if it only lasts a day.
