Now,Now, insulting doesn't get anything done. I personally believe that there is a glitch in the engine that occurs with some downloads. 4.8 had the same problem. There were time it would eat memory like crazy, you go to uninstall and either repair it or update it and a knew engine gets installed repairing the problem. It is doubtful that any of the shields are causing this problem, and if it was a shield, it would likely be the web shield since it occurs while surfing. Verification given that it doesn't slow gaming. The ALWIL team needs to evualate this issue with the CPU usage as a separate issue. Something that has been existing in 4.8 and has been carried over into 5.0. In the meantime, repairing or updating is the only cure to the issue I know of.
