I also got malware warning from Windows Defender on two separate PCs, for the exact same file. Once it is reported as "Trojan:Win32/Tiggre!plock" and the other PC reports it as "Trojan:Win32/Bitrep.A". Strangely enough, the file is digitally signed by Mentor and the signature is OK - so I wonder if it is a fake warning or the file is indeed infected...
There have been a couple of reports recently of anti-virus utilities reporting problems in the "dll" files within the ...\SVX\ixn folder when installing Xpedition AMS (previously known as System Vision).
Our engineering team is working to ensure that those files don’t get quarantined.
Those files are not needed for regular Xpedition AMS functions, and are only used by Xpedition AMS conneXion (SVX). If your virus checker removes the dll file, only the conneXion tool will be affected - you can continue to use Xpedition AMS without any problem.
