Trying F-Secure Internet Security Technology Preview and it found an AutoCAD related file suspicious.
Result: 1 malware found
I submitted the file and got the following reply quickly:
The file Acad162_icon.exe you submitted is indeed clean. A database update will be released to resolve this issue.
A problem I run into with the F-Secure Internet Security Technology Preview on Windows Vista was that when I tried to stop a virus scan because it took to much process power from other programs running everything slowed down and I eventually had to restart the computer using the button on the PC. I will see if they come up with a solution for that.
