[UPDATE: as I had feared, Avast services refused to load at all this morning, and as I write this it has been removed again, and I'll be switching to another product unless/until this glitch is found/fixed. If any developers are reading this, it may be related to multiple user accounts and/or admin vs standard accounts on a single machine, because things appeared to work normally under the Admin account, all the problems affected the standard account under which I run at all times except when installing software. Also please see my second post below.]
Windows 7 x64 Home Premium - Avast Free 17.2.2302 (build 17.2.3559.0)
After updating from whatever the last version was, I encountered the embarrassing "UI failed to start" error, so I uninstalled using AvastClear, rebooted and reinstalled. Happened again, uninstalled again, re-downloaded both the full and stub installers just in case, reinstalled. Happened again. Third time was the charm.
BUT I have no Avast systray icon. The sevices all seem to be running, and the icon appears and behaves normally once I click the desktop shortcut, but that ain't right. I have checked every setting in Avast, I have checked my systray customizations, I have used CCleaner to delete the tray notification cache and I have repaired and rebooted more times than I care to think about -- nada nothing nohow, I am iconless. I've even tried turning it off and on again.
This is not only a PITA but something that leaves me with an uncertain feeling Avast may not be working properly in all other respects -- though it claims to be. Searched the forum here, saw nothing, and now I'm at a loss. Would LOVE not to have to un/re/install a fourth time in one day.
Any ideas appreciated; further details as requested.
