|Trojan.Win32.Trasher - trojan program.
Upon start-up, it copies itself to the Windows system directory with the MFC42W.EXE name, and registers this file in the Windows registry auto-run key:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run MFC42Profile = MFC42W.EXE
The Trojan then "sleeps" for about three minutes, and then creates a TRASH.BIN file in the Windows directory, and then writes to this file garbage in an endless loop;
thus, decreasing hard-drive free space by filling it with useless data.
Use antivirus (also check How To Remove section)Startup Optimizer to remove this trojan from startup.
