Hi David,

I took a few more screenshots of the problem. I got 6 avast! Network Shield warnings when I booted up today and a further 2-3 more once I opened my browser (Firefox 5). avast! seems to be blocking an instance of svchost.exe from opening derribazu.net/random file name & extension. I’m not 100% sure the process being blocked is the same with the high CPU %tage but seems most likely (PID 3620). I’m able to easily kill the process in Task Manager and all is fine after that (i.e. I get my CPU idle again). Could this be a false-positive? Following are attached:

  1. avast! warning popup
  2. Windows Task Manager shot (PID 3620)
  3. Svchost Analyzer shot (PID 3620)
  4. Security Task Manager shot (PID 3620) (next post)
