Need help removing malware

Viruses and worms
1

My computer has been infected with something that results in a fake windows security center popup telling me that my computer has been infected with the trojan win32.zafi.b. Neither my antivirus program nor my antispyware program can find the source of the problem. At the suggestion of another post I read, I downloaded Hijack This and ran that last night. Below is a copy of the log that resulted. Can anyone help me figure out how to get rid of this problem?

Thank you very much for your help!

I suggest you try these steps:

  1. Disable System Restore and re-enable after step 3.

  2. Clean your temporary files.

  3. Schedule a boot-time scan with archive scanning turned on. If avast! does not detect it, try Dr. Web CureIt instead.

  4. Use SuperAntiSpyware Free or MalwareByte’s Anti-Malware. It is safer to send the infection to quarantine than delete it.

  5. Test your machine with anti-rootkits such as F-Secure Blacklight or Trend Micro Rootkit Buster.

  6. Immunize your system with SpywareBlaster.

  7. Check if you have insecure applications with Secunia Software Inspector.

Thank you! I will definitely try this. How do I disable system restore? Is that through avast or windows?

Click Start > Go to Control Panel > Double click on System > click on the System Restore tab > check the box that says Turn off System Restore > Click Apply > and Click Yes > Then click OK.
