Starting a few days ago, I would periodically hear an unfamiliar alert. When I heard the same alert today I was not actively doing anything on the PC. I traced the tone to Program Events related to Windows User Account Control. When I tried to Change User Account Control settings myself, the only option available is to set the conditions that cause a Change User Account Control Settings Program Event alert. When I tried to make a change myself I got that prompt that asks if I wan't to allow a program to make changes to my computer to which I clicked "No". I found that this is the only option under User Accounts that generates the above menioned prompt. The program that wants to run is described as being Microsoft's with a name of UserAccountControlSettings. It's modification date is OK but it's certificate describes it as being used for "Windows Hardware Driver Verification".
I know what I think is going on but want to know how many folks here come to my same conclusion (which I didn't mention on purpose).
