I may be the only one to have experienced this,
but I’ve witnessed an interesting and somewhat
irritating side effect using Avast. Whenever it is
running, doing a virus check, I’ve noticed that any
commands carried out such as opening up a folder or whatever
remains on the screen. The only way I can get rid of this is to
right click and open up the menu, then close it.
The phenomenon is restricted to Avast only. No other
program does this.
If any one else experiences this, I’d be interested to know.
There is a work around to these graphical artefacts remnants of menus, etc. that you could give a try.
Graphics glitches, etc. - Edit avast4.ini using Notepad [Common] section, add the following line to the section SunbeltKPFHack=2, save the file, you will be prompted by the avast! Self-defence module if this is OK answer Yes.
I have only had this once and it was as a result of a stalled process (not avast) in the task manager and once I used the End Process button, no more remnants.
