"Great product, prevents Startup being altered"
Been using for several years. Good solid product that prevents Startup processes to be altered unknowingly. I have it running at bootup time on 2 desktops and one laptop and have not noticed any slowdown in processes.
I run a scan about every other day and after the first few days, system has remained clean. Note: I also run CCleaner and ASC daily, and Malware and Super Anti about once a week (alternating).
Wish it would automatically do the updates, since it is brought up at bootup time, as well as automatically do the Immunize.
Great product; has caught several attempts to update Startup without my knowledge.
