hi, my english isn't good but i hope someone can help me.

a few days ago my pc is processing very slwoly, the corel draw program shutdow unexpectly, mozilla firefox and internet explorer are not opening, and sometimes i have to restart the computer because it crashes. So i runned the Spyware Terminator and was listed about 40 problems with the name "Heuristics.Broken.Executable".

I did the scan with HijackThis, and my log was:
