I have a big problem with my laptop as when the windows is started up and a
speicial icon appeared on the taskbar, the windows is converted to a dummy
otherwise its seems good.

I have a printed screen for that icon, but i don't know how to post it!!!???

at the last time i have installed a 3 antiviruse programs but no result, but
some times during the scaning the sysytem was stoped and a blue window (with
error message talking about new hardware or software not compatible).
