About Lorry
Expertise
I can answer most questions regarding viruses/Trojans and help to remove them.

Experience
This happens to be of interest to me as it boggles my mind that people have nothing better to do than to write a virus. Wish these people, the ones who write viruses would put the knowledge to good use instead. My job as a local tech involves removing viruses and/or spyware.

Answer
Hi Logan,

I saw three things that should be removed.

1-c:\WINDOWS\Fonts\lsass.exe
2-O4 - HKLM\..\Run: [lsass] c:\WINDOWS\Fonts\lsass.exe
3-O4 - HKLM\..\RunOnce: [lsass] c:\WINDOWS\Fonts\lsass.exe /RunOnce

Make sure you disable System Restore before deleting them. Once deleted, reboot, verify that they have been removed, then enable System Restore.

Another way would be to use Internet Explorer, go to:

http://security.symantec.com/sscv6/default.asp?langid=ie&venid=sym

Click the GO button, then under Virus Detection, click Start. You might be told that you need to download and install ActiveX Controls for the scan to work, answer Yes.

Write down exactly anything it finds, then go to: http://www.symantec.com/search/  and do a search for what was found. Symantec usually has a removal tool and/or directions for removing manually. Make sure that you follow the instructions for removal, step by step, especially the part regarding disabling System Restore.

Hope this helps!
Lorry
