Well ,after that i deleted the avg keys in the registry , i installed a new avg free setup ...
During installation i denied the resident shield , the control email , denied the restart ,asked at the end of the setup .
I got the icons in start-programs ... and to avoid the background process ( it was cause of blank screen temporary after the restart) i stopped this service in start-run : services.msc .
(btw, my o.s. is XP) .
So ,now, all well ... like in a fable , XD
resuming :
Antivir seems nice but i found out that it has an update system very average(my cpu goes in overload)
Other antivirus or are evaluation products or are too much beta(like gladiator)
AVG free edition is still on the waves
