    How does Malwarebytes 3.0 Premium perform a real PC with a clean installation of Windows 10 AU Home?
    - Only Windows Updates applied.
    - No other third-party security installed.
    - Default privacy and security settings.

    First of all, Malwarebytes 3 Premium performs great on its own.
    Now... Microsoft needs to improve its own Windows Defender, which knows to bog down system quite obvious. Malwarebytes 3 and WD together have impactful performance degradation. On its own M3 (as i use it) is a light antimalware product (measured on high/mid configuration). In comparison it is lighter than WD as a single solution.
    Some people wrongly equate RAM usage with system slowdown or whatever, if you do care or have a need for small RAM imprints look elsewhere - it takes about 300mb in my case , but that also depends on the PC configuration.
    Will it be enough to protect you... well that only depends on your behaviour on the net :). In my case WD is more than enough, but until it is optimized better i will continue to use M3 Premium (lifetime licence does help :) )

  3. Guys thanks to you all for taking the time to participate to this poll and your answers ;)

    It's good to know that i'm not the only one having issues (i actually uninstalled Malwarebytes 3) and to know your point of view.

    Hopefully the guys at Malwarebytes will read this or similar posts and will adjust their product accordingly.

    I have 5 computers but only tried 3.05 on four of them.

    I was able to install it on 2 of them and they "sorta" work but could not install it on the other 2.

    What scares me is the fact that all of my computers are pretty much the same.

    I am waiting patiently for a fix. Fingers crossed.

  5. It uses 2% CPU but 1000 Mb of RAM for me.

  6. Try and figure out what's different with the computers you had a problem with. Maybe you have different AV or a different OS ? Also restarting several times helps sometimes. As far as i'm concerned i had no trouble upon installation. Only the slowdown issue. Hope i helped ;)
  7. Strange, it used less than 400mb of ram on my PCs, even with 2 users connected. As for the CPU usage, i had strong spikes when using web browsers, especially when opening the browser or new tags.

    It's funny to see how we different issues and results with the same product tough :p

    Same antivirus and same everything.

    I'd rather have the Malwarebytes people fix it.

    Only use Malwarebytes Anti-Malware as a standalone scanner since 2008. Now with v3.0.xxx there is 90-100% CPU usage when running a quick scan. Not going to waste my time with a full scan test. I have tried all three versions of 3.0.xxx. All were exhibiting same behavior. Just uninstalled and reinstalled Malwarebytes Anti-Malware v2.2.1.1043 for the third time. High CPU usage is totally unacceptable. On the Malwarebytes Anti-Malware forums it is stated that the full CPU resources are used to "speedup scans". Seems counter productive to me... If not corrected I'll have to find another standalone scanner.

  10. I really used to love Malwarebytes but i can't help but feel that version 3 won't be much improved. It has to many flaws and i think that in order to fix these issues they're going to need to make changes to the core of the product.

    They messed up with version 3 and i think that we'll have to wait until version 4 to see some real improvement. Still i don't know how long that's gonna take and what impact these issues will have on their reputation.

    In my opinion it is still a great on demand scan if you use occasionally but that's it.

    Same here!

    Malwarebytes Anti-Malware 3.0 is consuming maximum memory of 300MB continuously as shown in task bar.

    Even Windows op. System memory usage is very less.
    Malwarebytes Anti-Malware is light weight and consumes very less memory usage.

    Also CPU usage is quite high.

    These problems are creating haevoc in the computer system !!!

    Untill these are solved I cannot use it.

    MB seemed to be somewhat of a resource hog as of late. Love the protection and the software, but I feel it's a bit bloated (at times). Had to uninstall it and went with Heimdal. Too early for me to say, if it good or not, but it's definitely much lighter with whatever I'm missing from the all-in-one solution.

    OK so I installed MB3 last night and launched a full scan.

    It completed by the morning and I was low on RAM. I have 24GB installed. Closing everything and looking at the task manager revealed nothing...still had 20GB tied up somehow. A restart cleared it.

    For some reason it started to nag me a few days ago whenever I really don't need to know about it (while playing an FPS, my screen will suddenly minimize, because Malwarebytes has to urgently tell me about the update for the umpteenth time), so I'm really considerung uninstalling the whole damn thing. So annoying. :mad:

    Malwarebytes lost its way some years ago. This new version uses a lot more CPU and the scanning speed seems low. Malwarebytes fell much behind its competitors and there is no advantage in having it. I personally own a licence but don't use it. Detection rate is much lower than Zemana for use as on demand scanner. Realtime protection is a joke. I wouldn't consider Malwarebytes Anti-Malware to install on my system until maybe a version 4 comes out.

    Similar problem. First I was mad that I was told I couldn't use my existing licenses (5) for version 3, I find I could have so I wasted money buying new ones.

    I have done a clean install twice in two days on a W7 Laptop. Chrome took 12 seconds to load after MB3 was installed, about 1 before. Nothing else, not previous files just Windows and MB3 - pretty conclusive.

    How do I go back to 2.2?

    I reinstalled it after doing a clean install of windows creator update and my PC froze!
    Had to do a hard reboot and boot into safe mode to uninstall it.
    Think i'll avoid this until they sort it out.
