With the New Next Generation Scanning Engine, unfortunately you can only exclude files. Even then if deemed Suspicious/Unknown they will will also be detected.
Thanks for the update. I've just found that the application thats running as a service is also now getting Quarantined, Presumably as its generating the temp files. As there is no method to stop McAfee from Quarantining these legitimate files i guess i'll have to move to another antivirus product that supports exclusions at a folder level. Im happy that the application is legitimate. Shame as i've been a big fan of McAfee for well over 10 years now,
Also today my son found his game "Just Cause 3" also got Quarantined with the executable removed after performing a steam install. Seems McAfee is quite sensitive.
Thanks for your help.
You are quite welcome. Please note that most Major Anti-Virus Vendors initially quarantine Steam/Minecraft/Foxhud Downloaders/Unpackers due to revised Version updates.
