Thanks Technical, the ‘ShowHelpCheckList’ was not in the [Simple] section of avast4.ini, it is now.

Just going to re-boot after this post, I will let you know what happens later.

Last night I, did and Add Remove/Change removed providers not in use, followed by a Repair, no difference. So, I uninstalled avast, rebooted, cleared the registry (RegCleaner), rebooted and re-installed, no change to current situaton.

I have IE6 fully updated, although I tend not to us it in preference to Avant 9.02 build 021 (set as my default), I also have FireFox 0.8.
