A definition update for Malwarebytes causes Trojan.Donloader.ED false positive on a massive amount of files that it can disable your system. It was corrected with new update. It hit me this afternoon and sure glad I had a recent Macrium Refresh image.

It really screwed a lot of systems. One person had 2800 files quarantined. A lot can't use their systems because of the exe and dll files being quarantined.

It does not matter. Just do an update for the newest definitions before running a scan. The problem was a bad definition update.

Spybot S+D

Hello
I was disturbed to read this although we all make mistakes.

Years ago I used Spybot S+D but drifted away thinking it was not that current and used MBAM in its place.

Would you suggest switching back?

Thank you
Peter

I have read that Super AntiSpyWare is a solid program also.

I have both MalwareBytes and Superantispyware Pro. I won't be moving from either. I don't think Spybot has been relevant for some time. I have the Free Emsisoft Antimalware as well. A Guy

I am using as little 3rd party as possible so I hope Defender + MBAM do the trick; you are well protected.

This would not cause me to loose faith in malwarebytes. Mistakes happen from time to time, fortunately the impact of this one wasn't huge. Although for the people affected, unless they had a system image, I bet it seemed like a very big deal.

I agree. I will continue with MBAM and consider it an isolated incident.
