Malwarebytes update deletes legitimate system files
Whoops ? The popular Malwarebytes rolled out a faulty update earlier this week that flagged legitimate system files as malware. The security firm confessed to the mistake in a blog post on Tuesday, and assured firms that the update has since been pulled.
"It saddens me to report that at around 3PM PST yesterday, Malwarebytes released a definitions update that disabled thousands of computers worldwide," wrote Malwarebytes Marcin Kleczynski.
"Within eight minutes, the update was pulled from our servers. Immediately thereafter, users flocked to our support helpdesk and forums to ask us for a fix."
The update definition made it so Malwarebytes protection software treated essential Windows .dll and .exe files as malware, stopping them from running and thus knocking IT systems and PCs offline.
The INQUIRER has heard from some IT managers that the update caused untold havoc on their systems.

My PC must've slept through this particular update. Fortunately, I've never had anything like this happen to me over the years, but then again, I never allow any security suite to do anything automatically without my consent - and if it did, it'd be off my drive in an instant.

At least include the forum message that describes the steps to fix the issues rather than just reporting the screwup...

I wouldn't use Malwarebytes as a full time, always on scanner, but they're still one of the better scanners out for the quick scan.

Kapersky is hardly the last word in security.Version 9 made my system Bluescreen. While this isn't a reason to ditch it completely neither is this mistake by Malwarebytes. Mistakes happen and the update was only live for about 8 minutes and they removed it.It is still a good tool to have along with others as no one thing fixes everything.
I stopped using this piece of trash 4 years ago. Products like Kaspersky automatically uninstall it due to incompatibility.

It's not a trash, i'ts quite good anti-malware program actualy, it's Chameleon is very nice anti-malware program for removing all sorts of malware on highly infected systems.
I'm also using Kaspersky Internet Security and Malwarebytes Anti-Malware (free version, without real-time protection) for years now at my home computers (never had less than 4 computers at home, currently I have 5 PC's, all of them are using KAV/KIS + MBAM) and never had any problems with MBAM. But if you use it with it's real-time protection + virus real-time protection (Kaspersky or any other) then you can expect problems, both of them are trying to do a same real-time protection jobs in the same time witch is obviously disaster waiting to happen...
You probably had forgotten about problems with Kaspersky update some 2 months ago when few milion users worldwide were left without internet on their Windows XP PC's: http://www.panarmenian.net/eng/news/144699/ One of my computers at work had that problem, detailed uninstalling and reinstalling of KIS 2013 solved a problem. But that small problem with KIS back then didn't shake my faith in Kaspersky, that could happen even to the best so don't judge about MBAM badly just because you don't use it more than 4 years. At least their reaction was fast and they offered a quick solution for problem for their customers.
