My malware app is reporting a Trojan.YZST.9002 loaded from Firefox executables
My System Mechanic malware search system has quarantined a virus located in two Firefox locations: Virus is W32/Trojan.YZST-9002 LOCATE IN: C:/PROGRAM FILES/MOZILLA FIREFOX/UNINSTALL/HELPER.EXE C:/PROGRAMFILES/MOZILLA FIREFOX/MAINTENANCE SERVICES_UNINSTALL... I will use the delete process and remove them and watch for future loads.

I have been using System Mechanic for many years now and it just recently found two files named above within mozilla folders. They had been moved to quarantine and I deleted them yesterday. I did see one reference to the files via google so will leave this out there in case others see it.
Those files are quite normal on Windows. UNINSTALL/HELPER.EXE is the uninstaller for Firefox.
MAINTENANCE SERVICES_UNINSTALL is the uninstaller for the Mozilla Maintenance Service that is used to update Firefox in the background.
Both these files interact with the program folder, so that might alert System Mechanic.
I wonder why System Mechanic only recently thought the two normal things are trojans though, besides being false positives hmm.
