The avast update or installation for that matter shouldn’t have any effect on the taskbar icons.
There has however been a windows security update that by all accounts conflicts with the creative sound cards, I don’t know if this might have had an effect, but since t also effects another icon ATI Tray Tool perhaps not.
Does clicking the < Show Hidden Icons reveal anything ?
If not you may have to go into the control of these applications and change the settings and reset the tray icon.
I’m running 4.7.981 and no issues with the tray icons, nor can I remember any try icon issues in the beta testing that was done by forum members prior to this release.
