Well it gets stranger, I can replicate the same issue in ewido even after a complete uninstall, registry clean-up of avgas, I never had a single problem with Ewido before.

Another point though when closing the ewido window after a scan the ewido.exe is also closed and removed from the task manager list (as I believe it should), so that differs from avgas.exe. I also noticed that there was no 30 trial period indicated as it did before even when upgrading from the earlier version and no entry for ewido on the msconfig, startup tab.

So even though I have cleaned registry and rebooted there would appear to be some form of hidden details to indicate I’ve already had 30 trial of ewido 4.0, not that I’m unduly worried about that.

I have however, to disable (set to manual) the guard.exe service from starting automatically on boot and see if that makes any difference.
