Note : When you download the 4044updt.exe files from their website you have to execute it, then during the execute the setup writes all its files to C:\TEMP\~EXB0000 or C:\WINDOWS\TEMP\~EXB0000. These files must be copied to @LDRIVE + "\Virus"
Also, Mcafee can't disable it's own scanner, It copies the SCAN.DAT file as SCAN.OLD, when you then restart your PC, SCAN.OLD overwrites SCAN.DAT. So it takes 2 login times to update the scanner ...

Hope this helps a bit...
