After installing MS Win10 creators update my G Data Total Security not working. Its says "Invalid certificate" or "module cannot be loaded". I have tried to uninstall and reinstall but still same issue. I tried to install Kaspersky, MalwareByte etc too, but same issue.
GData support sent me all valid certificates separately, and I added them to Trusted Root Certificates through MMC. Still same issue.
Scared of virus, ransomware etc now. Pl assist.
