Did you use the removal tool when removing avast?
If not, give it a try.
Also use the search option on this webboard.
I recall seeing this problem before.
Don't know if they found a solution or not.
-I used control panel to uninstall
-Restarted
-Opened the uninstall utility which restarted into safezone, ran and restarted into regular mode
-Reinstalled, saw the problem
-Tried to repair and restart, no luck
-I used control panel to re-uninstall
-Restarted
-Opened the uninstall utility which restarted into safezone, ran and restarted into regular mode
-Rereinstalled, saw the problem
-Tried to repair and restart, no luck
-Dealt with it
My WinVista and Win7 computers did not have either of the safezone icon problems.
I did a search. I saw other safezone problems, but not this one.
