My computer (Dell with Windows XP)slowed down dramatically two days ago. I looked at my automatic Startup Programs list and found the topic title listed above. After posting for help under bc's Startup Programs forum and getting suggestions from two members, I ran McAfee A/virus scan, which found nothing, then Malwarebytes Anti-Malware (just the free download version and the Quick Scan), which identified 8 infected items. Even though I could not see anything vaguely resembling the letters in this topic title, removing these 8 items and rebooting solved the problem. Maybe this post will help somebody else who encounters this problem.

Hello, would you please post that MBAM log.
The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.

Then do an Online scan.. XP

Please perform a scan with Eset Online Antiivirus Scanner.
This scan requires Internet Explorer to work. Vista/Windows 7 users need to run Internet Explorer as Administrator.
To do this, right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run As Administrator from the context menu.

• ESET will then download updates for itself, install itself, and begin scanning your computer.
  
• If offered the option to get information or buy software at any point, just close the window.

If you did not save the ESETScan log, click > Run..., then type or copy and paste everything in the code box below into the Open dialogue box:

C:\Program Files\ESET\EsetOnlineScanner\log.txt

• Click Ok and the scan results will open in Notepad.
  
• Copy and paste the contents of log.txt in your next reply.

-- Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

NOTE: In some instances if no malware is found there will be no log produced.
