Dear Nano team
The latest Nano Antivirus works fine, but some cleaning programs can cause problems. It looks like too much cleaning (Glarysoft) is making a mistake on the internet icon on the taskbar or it appears that there is no internet connection. When I gently cleaned with Ccleaner, there was no internet icon problem. As a precaution, I reinstalled Nano Antivirus and everything worked fine again. I still have Ccleaner as a utility.
I'm sorry that I was looking for the problem of Nano Antivirus. The problem appears to be a user and cleaning program .
