Yes. With that on, only my internet connection is held back (as opposed to the ram cleaner, and the other standard windows taskbar items).
Avast initializes/loads... but the email and web shields (I believe) are disabled, and the Avast taskbar icon displays the exclamation mark. At that point, the delay begins. CPU goes through the roof, and continues so for several minutes. Internet connection is still not established, and not much else can be done during this time. Seems to be either AvastUI.exe or AvastSvc.exe (or whatever that file is called) that is using up the CPU... usually up to 65% (fluctuating frequently). I usually click on Fix Now to try and activate the disabled Avast modules (as I'm not sure if they go on automatically after the CPU strain finishes).... but nothing happens (the program is too busy).
After several minutes, the CPU drain suddenly drops, the Avast interface refreshes to reveal that all disabled modules are now running again, and my internet suddenly gets activated (and Avast usually grabs the latest definition updates)... and things are back to normal.
So, I'm wondering what might be happening here, so I can further diagnose things... It doesn't appear to have anything to do with the update downloading, since it occurs before that stage. Not sure why the certain modules are disabled on bootup each time.
I DID find one user who wrote about the same type of experience, and a new user gave what he claims is a solution he found. He said the latest update DOESN'T fix things if installed the normal way, but instead needs to be installed in safe mode (...or something to that affect). I'm not sure if this is a true fix, as he might have just temporarily fixed it by reinstalling Avast (...and it might just come back again). I too was able to drastically reduce the delay by doing a repair on Avast... but the delay went back to 'several minutes' after a day... so, not a fix.
I've been hoping to get some official word on this issue... whether they know what is happening.... whether there is an official fix/repair method... etc.
