Details from the AV Scan report:
This is from a Linux system. The scanner was ClamAV with the very latest definitions./Lexia3/PP2000/PP2000_09B_22.14-New/DCS/tools/ENDINST.EXE: Win.Trojan.Menti-2458 FOUND
Information on the virus is scant but it appears to be a back-door.
For peace of mind I recommend a scan with an up-to-date virus scanner of any machines you may have with the Lexia/PP software installed.
I hope/pray this is a false positive generated by ClamAV but better to be safe than sorry...
