When I start up the computer, Avast now reports “Firewall is turned off.” I suppose this is referring to the Windows Firewall (I’m using Windows 7, 64 bit). Windows thinks its Firewall is on. Avast also gives me the option to turn on the firewall, but all I get is “Unable to start firewall!” This has happened a couple of times before, but I had to jump through so many hoops to get rid of the error that I was never even sure what I did in the end to fix it. Any ideas?
If you try unistall avast from ad/remove programs, there will be a option to repair avast … run avast repair
