I'm sorry if I'm a bit late to this discussion (I don't normally monitor BleepingComputer for topics about Emsisoft products), however there is a way to prevent everything in the Steam folder from being monitored by Emsisoft Anti-Malware's protection. Here's what to do:
- Open Emsisoft Anti-Malware from the icon on the desktop.
- Click Protection.
- Select File Guard in the menu at the top.
- On the right side, roughly in the middle, click on the Manage whitelist button.
- In the box under Type click the little down arrow and select Folder (you may need to click in the box for the arrow appear).
- Click in the gray box below Item to make a button with three dots (...) appear, and then click the ... button.
- Navigate to the directory you wish to exclude, select it, and click OK at the bottom to add it.
- Click the OK button at the bottom when done, and close Emsisoft Anti-Malware.
For those who don't know, Steam can use the following folders on 32-bit editions of Windows:
C:\Program Files\Common Files\Steam
And the following folders on 64-bit editions of Windows:
C:\Program Files (x86)\Steam
C:\Program Files (x86)\Common Files\Steam
Please note that folder exclusions do not prevent the Behavior Blocker from creating hooks to processes that are running out of those folders, however it will cause the Behavior Blocker to ignore those processes rather than monitoring them. If you have issues that the folders exclusions don't fix, then you can add Process exclusions for individual executables as well to prevent the Behavior Blocker from creating hooks to those processes.
I'll try to keep an eye on this topic for any replies, but please note that I don't receive e-mail notifications from BleepingComputer for some reason, so I might not reply right away.
