I'm also getting this error regularly, and it's getting quite tedious. I'm disappointed to see the last comment from AVG to be back in April with no resolution. I followed Yamuna Sathiyamurthy's guidance but nothing was in red so there's nothing to immunize. What does yellow mean on that tool?
I've been a loyal AVG user and advocate for about 15 years but, if I can't find a solution for this, I'll have to dump this and move to another solution.
Please, AVG... please provide a solution.

I have been using AVG for years. After the update to AVG 17.3 I keep getting a notice that AVG found a Threat and Secured it. AVG requests a computer scan which I have done numerous times.
Every 5 to 10 minutes, AVG continues reports the same Threat as being secured in the quarantine area. However, there is no threat in found in the quarantine area as it states. This appears to be a "bug" in v 17.3. This does not happen on my other computers running AVG16.151. I also noted a similar issue with an user having trouble logging on to a Bank of America Site. It seems as though the same message is being shown with different urls. Would going back to an earlier version correct this issue? If so, how can I go back to an earlier version of AVG?
Yamuna, I did as you requested and ran AVG AutoExec and did not see any files in Red Color. I will restart my computer, but I think the problem will still be there since there was nothing to immunize.

Larry, Quote "how can I go back to an earlier version of AVG?"… Unfortunately I'm afraid that earlier versions of AVG are now no longer available.

I am pretty sure it is a bug in the AVG 17.3 Build. Than how do you suggest that I solve this issue?
