In todays patch (March 9). Gameguard has been updated.
What's the update? Unknown, unlikely to be publicized.
As stated from the Changelog from today's maintenance it is to further enhance detection Of 3rd party softwares.
There's no official list of software that gameguard considers malicious.
This may include the viperbot, i4t, or even simple macros
(unsure about macros, since Razer peripherals uses macro (or any other high-end peripherals)).
However, the antigg.dll still works. Version.dll works but not recommended.
There's no guarantee that what they post "is real" or "all of it".
I (own opinion) expect, they also changed something server side to further enhance detection.
What has been Tested
Using a software that detects, driver installation.
It appears that the updated gameguard IS NOT installing driver file into your System Folder.
To double check, I run another game with Gameguard and here's the result.
What was not tested
- Heartbeat. Using antigg.dll & Version.dll, seems to work but did not wait long enough to see if there's a heartbeat.
