Well this is embarassing:Avast Interface failed to open not protected.

[REDACTED]

Ever since upgrading to the latest Avast a few weeks ago my computer  running Windows 7 has been left vulnerable by my Avast Internet Security failing to load. I have no idea how to sort this out and am very frustrated. I am a lomg time paying customer of Avast but I will not be dealing any further with you if this is not sorted out.

Can anyone tell me what the hell is going on and how to fix it please.

Thanks.

- Which version of AIS..?
- Other security related software installed..?
- Which AV(s) did you use before Avast..?

If Repair doesn't fix the problem, try the following:
Clean Install of Avast:
