Since enabling the logging a couple of nights ago, I hadn't had a lockup until I was replying here saying that the problem hadn't occued since enabling the logging...
The programs I was running at the the time were Firefox, Ventrilo server, Ventrilo and iTunes (which had been busy downloading prior to the lockup).
I used the userdump program from the other thread to capture a dump of the ashWebSv.exe process (and discovered that I had to disable the avast self-defence module in order to do so) then disabled and re-enabled my network adapter and was able to resume normal service. Since then I've been running Guild Wars, Ventrilo server, Ventrilo and Firefox and things are still working ok at the mo.
Could someone tell me if the instructions in lukor's post (

Looking through the AshWebSv.log file doesn't appear to point to any causes - there is just a pause between when things seems to have hung up, and when things resume after I re-enabled my adapter.
Following info's lead, I also had a look at the Event Viewer, but could not find any events which correlate with the Web Shield lockup.
DavidR, thanks for the HJT links - it found another leftover from AVG8 which I removed:
O2 - BHO: WormRadar.com IESiteBlocker.NavFilter - {3CA2F312-6F6E-4B53-A66E-4E65E497C8C0} - (no file)
info, since you're using Vista do you have the ZoneAlarm compatibility settings enabled in the [WebScanner] section of your avast4.ini file? (
