Hope it’s OK to jump in on this issue.

I’m having the same problem, though getting the RPC error.

Last night I followed the Faq and managed to get Avast! re-started as resident.

This morning I can’t get it restarted no matter what.

Don’t know if this is a coincidence - but I get multiple windows of Internet Explorer starting up and trying to access a URL.

It does ‘look’ like something on my PC is stopping Avast! from starting.

XP64 and using Windows firewall. No other firewalls or virus checkers installed.

Any thoughts?

Many thanks.

Dougie.
