Hi, I am using the latest Avast Free Antivirus software with latest data base, on windows 10.
I have a home network with 10-15 IP addresses (tablets, smart phones, laptops, PCs, printer etc.).
I have 2 PCs with Avast Anti Virus on them.
When ever any one of these 2 laptops connects to the network, it crashes my ISP home router which then reboots. This is really annoying because I am working in home office and I am kicked out of the Teams call I am on until my Internet connection restarts.
Looking at the logs, a few seconds before the router crash, I see this: "SSH user logged out"
This is really scaring me because I did not do any port forwarding on port 22, so SSH should not be possible from the outside. I hope that I have not been hacked.
I suspect Avast AV software on those laptops to be the origin of this problem. Since this morning I dis-installed all Avast Antivirus software from all my PCs. I have not see any more crashes of my home router, and would need a few more days of noticing no crash before I can consider this fixed.
My question to Avast is then: could Avast AV be generating behavior explaning these "SSH user logged out" messages and crash of my Home ISP router?
