Question
A
After you start AutoCAD, you get a strange unreadable messagebox "AutoCAD Message" that looks like this:
This is a result of a virus infection with the ACAD.QFAS virus (also known as TROJAN.ACAD.QFAS, acad.qfas.a). There are also new variants ACAD/Qfas.b, ACAD/Qfas.c, ACAD/Qfas.d in the wild.
Please use the latest version of your antivirus tool to get rid of this virus (trojan).
