I got an Avast popup message on my old PC which advised me that an add-on with a "bad reputation" should be removed (I did not write down the exact details). I said ok and it went ahead, then asked for a reboot. The computer now fails to boot Windows, crashing a few seconds into each attempt. Windows Restore is unable to automatically repair itself and I am still working out the best course of action (whilst trying to suppress my dark feelings towards Avast).
I am also left wondering whether the popup was a genuine Avast message or whether it was some kind of malware. If the former, Avast is meant to protect my system, not destroy it. If the latter, how did it get past Avast in the first place?
The system is Windows Vista Ultimate, regularly updated and historically trouble free. It is a 2007 HP Pavilion which is now my back up computer. Avast Free version has been installed on it since day 1.
Any advice or comments would be appreciated.
