Trojan Horse Blocked pop-up

Viruses and worms

I don’t know how to get rid of this pop-up on my desktop… I click on it to close it and it just keeps coming back. How do you get rid of it?
Thanks.

I suggest:

  1. Clean your temporary files.
  2. Schedule a boot time scanning with avast with archive scanning turned on. If avast does not detect it, you can try DrWeb CureIT! instead.
  3. Use MBAM (or SUPERantispyware or even Spyware Terminator) to scan for spywares and trojans. If any infection is detected, it is better and safer to send the infected file(s) to quarantine (Chest), rather than simply deleting them.
  4. Test your machine with anti-rootkit applications. I suggest avast! antirootkit or Trend Micro RootkitBuster.
  5. Make a HijackThis log to post here or this analysis site. Or even submit the RunScanner log to to on-line analysis.
  6. Clean your Hosts file (replacing it) with HostsMan tool.
  7. Disable System Restore and then reenable it again.
  8. Immunize your system with SpywareBlaster.
  9. Check if you have insecure applications with Secunia Software Inspector.

Allow me just to add that it would be also a great addition Spybot - Search & Destroy immunizations. Ditch the Tea-Timer component, though.
Also, use a different DNS service, such as Sunbelt ClearCloud DNS, which will block access to malicious websites.

a screen shot of the pop up may be? or what does it tell?
