I am in the process of moving to Windows 10 x64 and re-installing all of my main apps.
I installed the latest version of Applian Replay Capture Suite from their website this morning.
After installing I had loads of pop-ups from BitDefender 2018 (latest updates) saying that it was quarantining various items containing Atc4.Detection virus.
Slowly I watched as all of the icons from the the suite gradually disappeared form my desktop 
I have submitted a ticket to BD and also Applian but while I wait for a response has anyone else found this and do you know if it's a False Positive?
I also have Malwarebytes (latest updates) and it didn't complain of any problems.
Thanks
