I have been running into a problem when using NordVPN’s services and managed to narrow down the culprit.
After every time I would disconnect from a VPN, I would be unable to reconnect unless I reinstalled the entire program. After getting fed up with this headache, I did some digging and found out that avast! has been putting one of the integral executables for NordVPN in its virus chest, detecting it as IDP.Generic, whenever I would disconnect from a VPN. Here’s a screenshot. I’ve used NordVPN in the past alongside avast! without ever experiencing this issue, so I’m not sure why this has suddenly become a problem.
I’ve submitted the file as a false positive, but in the meantime, if anyone uses NordVPN and also has this problem, try checking your virus chest for the solution.
