Viruses and worms

Good day!
After a routine Avast scan, it found a WIN32:Sirefef-ZT trojan on my system.
I ran the adwCleaner, I wanted to post the report but it exceeds the character limit for the message.

Thanks!

Ok, ran adw cleaner again and saved the report in order to attach in my next reply.
Rebooted as asked by adw cleaner, but now i get a black screen with only my mouse pointer working.

[*]When finished, it shall produce a log for you.
[*]Please include the C:\ComboFix.txt in your next reply.

Notes:

  1. Do not mouse-click Combofix’s window while it is running. That may cause it to stall.
  2. Do not “re-run” Combofix. If you have a problem, reply back for further instructions.
  3. If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.

Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

I have disabled Avast, but the ComboFix is still giving me a warning that it detects its presence (anti virus and anti spyware).

12

Accept the warnings, but do not let Avast sandbox or quarantine any files… It shouldn’t do as it knows how combofix runs

Here is the log for ComboFix.

How is the computer running now ?
