I always do a scan every week and nothing found there (last scan yesterday).

My HD7770 runs on that temp since I set my computer completely fresh up (I delete all, install Win7 completely new and the HD7770 also, so there can't be a virus or anything else

.
Since this the idle temp is on 42-45 degrees Celsius and if you follow my links, you saw it is normal (cuz I linked a test of the HD7770 DD Edition, on it they is on idle around 43 degrees Celsius

.
So all is fine (I never had problems with high temps or anything else, when I play games, the card is max on 65 degrees Celsius with fan speed at max 50%, like I said before).
Thanks anyway.
I installed the AMD driver always without delete the old one, never got problems. The driver make all automatically (never get problems).
