Hello again, TrojanVictim666. Please tell us how your system is behaving.

Please save this page to Notepad in order to assist you when carrying out the following instructions.

Before beginning the fix, read this post completely. If there's anything that you do not understand, kindly ask your questions before proceeding.

It is IMPORTANT that you don't miss a step & perform everything in the correct order/sequence.

Quote:

  • Tick the box next to YES, I accept the Terms of Use.

  • When asked, allow the ActiveX control to install.
  • Close/disable all running programs, including your antivirus and all antispyware programs.
  • Click Start
  • Click Start
  • Make sure that the option Remove found threats is unchecked.
  • Make sure the option Scan unwanted applications is checked.

  • Wait for the scan to finish.
  • Use Notepad to open the logfile located at C:\Program Files\EsetOnlineScanner\log.txt
  • Copy and paste that log as a reply to this topic, along with a new HijackThis log and a description of any remaining problems.
