As a long time Avast (former AVG, former Norton) Free (Home) & Paid User (Business) use I have been reading this Forum before I did the V9 upgrade......been in this rodeo before when AVG when from great A/V guy to trying to be all things to all people and bricked thousands of PCs.....truly ugly time. Anyway, Avast has been great, simple, clean, fast, etc. This V9 is not only not that it should have never been released.....Outlook does not work, JAVA, VPN, Firewall, Browser, etc, etc.....issues.
Also, while I applaud Avast to have a EMU ability to that they can correct a potential brick situation I am floored there is little/no comments on this thread from Avast. After reading I went into MSCONFIG and found the attached.......note, I'm on V8....not V9/2014.
I can only provide a "guess" based on reading the thread that this EMU on Startup is there to avoid a corrupted Avast from corrupting your login and bricking your machine. I think the EMU scheduler item is there is periodically update Avast binary (program) code from Avast for items needed that neither require a reboot and/or fix items that a reboot may cause issues with. Thus, people disabling the EMU on startup may not see a problem if their Avast install is OK but they have eliminated the ability for this EMU to do its thing if there is. Of course, this is all a guess......WHY ?..........because no one from Avast is taking the time to comment on a thread that is not seven pages long.
