Hi, i will post some questions from time to time when i will have more expierience with this good security software. For the start i would like to ask what this means. Firefox.exe tried to install driver/service (Process ID 1876). Adobe_updater was blocked from reading firefox.exe (Process ID is the same). When should i be worried? Should i allow explorer.exe to install driver/service? This is not a default settings for explorer. I had this kind of alert some months ago. What kind of alert would be if my machine is about to be infected with kernel level rootkit? Thanks.
