Hi all,
I'm having the same problems others have reported. I updated the Avast IS to program 5.1.889 okay - all was well; then I updated the virus engine and definitions to 110222-1 and since then I can't connect a web browser to any site unless I disable webshield realtime scanning.
I've tried the winsock repairs suggestion - no help
I've removed in safe mode with the Avast utility and re-installed 3 times - the problem persists
I don't run any other virus / malware programs
I don't run any other firewall programs beyond Windows standard program
I am not aware of any other change on my PC - was working fine at 2am this moring - 6 hours later after the Avast update none of my browsers can connect.
I can confirm the rest of my network is fine (all PCs not running Avast are fine) - I can ping my DNS and ping
www.google.com.au fine - its just browsers that have stopped working since a few hours ago
Await your thoughts!
PS
One change that did help
I just then went into Web shield - expert settings -> Actions and changed the default action on Virus , Pup and Supicious Tabs from Abort connection to ask
Since then I can get to google fine. I then went back to expert settings and changed these values one at a time back to abort connection and re-tested. Appears working
