I have never heard of this file before, nor could I find it with a google search. Therefore, I believe it must be deleted.
You may have to repeat one or both of these next steps.
First, go to Start, Search, More advanced options. Tick each one except case sensitive. Type in the file name.Click Search.Delete every entry you can.Restart your computer.
Second, go to Start, Run, type regedit. Go to the top of the window to Edit. Go down to Find. Type in the file name. Delete every entry you can using the Find Next feature(if it is required). Restart your computer.
Update and run your antivirus. Then get a second opinion at House Call: http://housecall.trendmicro.com/ and McAfee : http://us.mcafee.com/root/mfs/default.asp
Update and run Ad-Aware and Spybot.
That should do it. If not, we will have to use HijackThis.
Hello again - I am having trouble deleting trrfki.exe from my system. I have used the task master to delete (first disabling my firewall from zonealarm) and then ending all tree processes Yet this still comes up on my system. I have tried looking under Sophos virus analyses to see what they suggest and trrfki is not listed. I am running Windows XP Home system - windowsxp sp1-win 5.1 build 2600.xpspl.020828-1920. Any help would be greatly appreciated. Thanks for your help.
