The only other security related programs I have are the mentioned Private Internet Access VPN and SUPERAntiSpyware Pro. This has been a new installation of AIS on a freshly installed OS, so there are no traces of old AV programs (besides, it has been good 10 years since I used anything other than Avast)

Haven’t tried repairing it yet as there didn’t seem to be anything else wrong with how AIS functions worked, once loaded.
