GGSafe isn't anti-virus, and there isn't cause conflicts GGSafe and Avast. So, Avast shouldn't report GGSafe.sys is Suspicious File. I suggest that avast ignore this report.
I got that impression from a couple of google hits, but it wasn't easy to find information not in Chinese - Notice I started the comment with 'If' as the search wasn't conclusive.
So if it isn't an anti-virus, then I would have to ask a) what exactly is it and b) why it is necessary to hide the service; which is what avast is finding 'suspicious.' ?
This however isn't a conclusive detection but a suspicion based on heuristic detection method in the anti-rootkit scan.
You could also check the offending/suspect file at:
VirusTotal - Multi engine on-line virus scanner and
report the findings here the URL in the Address bar of the VT results page.
