i just did a downgrade from vista back to XP. upon starting up the first things i got are IE popups. the next day msdos console pops up with a blank screen. then a window pops up reading
16 bit MSDOS Subsystem
C:\WINDOWS\System32\maxd641.exe
The NTVDM CPU has encountered an illegal instruction.
CS:0dc7 IP:0103 OP:db 74 01 4b 83 Choose 'Close' to teminate the application.
Spybot and AVG only detects the virus but cant really do anything to remove them although they "healed" it.
this is my hijackthis log, please advice!
