Hi, i have been using this product for a few years now and it has saved our computers more than once. ( love it) LAtely, when i do a scan on "C" drive only...it runs for a minute or so and then stops and says " No disk in "D" drive" "Please insert" ....Im only running a "C" drive scan, so im not sure why this is happening. The only thing i can think of is, a mmonth or o ago, i changed my peripherals at start up, to run a drive on start-up . But i am not sure what that should be set at.....Any ideas, so i can keep scanning the bad guys out of my computer without any probelms would be great. Thanks !
