Hello! Hope this is the right place to post this So I have Windows 7, and my computer updated recently. Since then, two strange applications have been trying to do random stuff: 'Windows Compability Advisor Inventory Tool' (Yes, there is a typo in 'compatibility') and 'Application Block Detector' Which ZoneAlarm tells me wants to load random drivers. I've had a quick Google, and I think they might be tied to Microsoft? But I don't know... it just seems really suspicious. Malwarebytes and Avast are coming up clear. An Avast boot time scan fixed the issue for one day, but sadly it has returned now I've had a look at my process list... and nothing seems amiss... so, does anyone have any ideas?
