I am not trying to downplay the problems you are experiencing ... but we have one thread in this forum with a small number of participants (just 2) complaining of this problem.
It may be that many users in one geographical area are failing to complain ... but what else is the avast team to work on?
My sens.dll does not register as infected with avast.
Have you sent a sample of the virus to avast?
One little comment....
How many users do you think report back???
Most users don't even know about this forum, and most people are afraid of complaining on a forum.
None of my friends and family have ever been to this forum.
The last days I have fixed 14 computers with problems after 4.8. They call me - not avast! I was the one who recommended avast!
A couple of them were just about to install a virus protection from a competitor...
6 of these computers had an infection [FF-patch] in sens.dll, and there wasn't even a copy of it in dllcache....
Om my computer the System Event Notification Service (sens) even disappeared totally. Not that I need it anyway...
2 had a dll called msfont.dll with the same infection.
The recommended lists of what to do with re-installation didn't work in most cases.
I always had to start avast in safe mode after install and deselect rootkit and self-defense.
Then, after some reboots the icons on the desktop appeared....
I could then enable rootkit and self-defense. On most of them I had to use the "Delay loading of avast" to make the boot stable.
All are now up running again.
But please - don't think this forum reflects everything going on in the whole wide world!
Most users are suffering without avast knowing it......and the problem with this is that the worlds best anti virus program could lose a lot of customers....
