I just started to use avast!, Version 4.1 Build Mar 2004 (4.1.357). everything is excellent, but there’s one thing. the popup, that displays on-access scanned files really annoyes me. the question is : how can i get it dissapear? thanks for the answers.
Strange,this option is turned off by default ???
Open On-Access panel,select Standard Shield and click Customize…
Now click on the Advanced tab and uncheck Show detailed info on performed action. Click Ok and Ok again. Here you go,thats it 
thank you so very much. i did it 
No problem ;D
