avast blocked watchguard

We are using watchguard VPN client and avast.

It had been working well till yesterday for more than 6 months.
Suddenly avast marked watchguard as malicious code and blocked it. Even after trying to add it as exception it didn’t help.

Then we tried to reinstall the watchguard VPN client but then also it didn’t help.

Anyone facing similar issue?

Any solution to get it working?

Mohan
