I've been in professional IT for over 20 years now, so I'm the family central support guy. I have used Eset Total Security for many years now and not had a problem, but this morning I got a call from my older sister, to whom I recommended Eset several years ago, saying she was ready to smash all her computers.
After some troubleshooting, I found she was unable to do anything, and the firewall was showing that it was blocking traffic from every device on the network, including the network firewall/router. It was also blocking everything going out, including the DNS client! What's worse is that her daughter's Surface Pro is doing the same. Trying to bring up a browser gives a security warning just as it is starting. The browser starts, but nothing displays on it. She can't even print, as the firewall is showing that it is blocking traffic to (and from, somehow) the network printer. I live 2 hours from her, so I can't just drive down to troubleshoot and fix this myself. The earliest I can get down there is Friday.
I don't get it. I have never seen this behavior from anything before. The closest I've experienced was when Bitdefender had their bug that identified all x64 executables as viruses. (That was the reason I switched from them to Eset, so many years ago.) I directed my sister to call Eset support, but I don't know how well she'll fare with this. Her temper is legendary, and she is riled up right now, and I don't know how well non-family will handle that. (I really hated to throw her their way, but I had nothing for her.)
Has anyone else experienced this? If so, what caused it? I'm baffled.
