Whoa! You must live dangerously, mchain.

I’ve used both MBAM Free (and Paid) and Windows Defender since their inception, and neither has detected a single thing over all those years. (I was an original beta tester of MBAM, and was given a free licence to MBAM as a result).

It is interesting how users’ experiences differ. While WD never gave me any trouble running in real-time, I was never able to use MBAM (paid) on my XP/sp3 system , because it always slowed down my system and browser to a crawl. I never did find the source of this conflict. Even with all other real-time protection programs disabled, I could not get MBAM Pro to work in real-time without serious slowdowns.

I have been impressed with how WD always detected systen changes I made over the years.

I continue to use both WD and MBAM in real-time on my Win 7 systems, without problems.
