Windows Defender virus detected – Ansys mechanical

    • Sam Rolland

      The mechanical solver is picked up by Windows Defender as a virus. This happens to existing installations and during the install process for any new installs. 

      This has been happening since 24 March 2023.

      • Detected: Trojan:Script/Wacatac.H!ml
      • file: C:\Users\**********\Downloads\ANSYS _FILES\ANSYSACADEMICSTUDENT_2023R1_WINX64\solver\WINX64.7z

      This needs to be resolved urgently please!

      Hello Sam,

      I just scanned the download and receiveed no virus notifications.

      I also ran an installation and there were no virus notifications and the installation was successful

      Running a test project produced no virus notifications either.

      What Operationg system versions are on the machines?

      What version of Windows Defender is on the machines?
      Was there a System update on or around March 24th?

      Hi George, thank you. I ran the virus definition update last week and was able to re-install Ansys. I think it is solved.
