hello everyone, lsn,
in the begining the avast tray icon was there, but after the second reboot, it disappeared, i tried on the settings, but hopeless, and everytime i open avast, and then i close it, the avast protection goes, and i become unprotect as i was used to, so plz help me abuot this. let me tell u that i’m using Avast Home Edition
Try a repair of avast. Add Remove programs, avast! Anti-Virus, Change/Remove button and scroll down to Repair, click next and follow. You need to be on-line to do this.
If that doesn’t work try, uninstall, reboot, install, reboot.
Or failing that:
Repair! missing avast icon download RejZoRs restore missing avast! icon tool - http://freeweb.siol.net/razor256/downloads/aswTrayIconFix.zip
Download it and extract aswTrayIconFix.exe anywhere you want.
Run it and just click Fix button. Log off and log in again or simply restart your PC and icons should be back again. The program is standalone extract&use (although it looks like installer).
thx a lot DavidR for ur help and it worked perfectly 
Happy to have helped, if it was RejZoR’s missing tray icon tool he deserves the thanks.
