Malwarebytes uses way to much cpu
I am not sure its mbam that hanged my pc !! In fact the boot was nice after removing Mbam but not the ' plug and play ' on external drives on usb,, stil hanging the pc and not recognized, so I added a 'service on windows that had been disabled,, ' and now all my external drives are recognized on plug and play,, so nice (!!), what I have to do is to restore the pc in the state it was when I had mbam in msconfig services (!) and put that windows service again( not the mbam one),, and see what happens, I really want to 'understand' I will let you know further if mbam is really in cause,-, but in fact, taking off mbam resolved my boot,,maybee its not the only one in cause in that 'troubles'..
I had the Malwarebytes free version. Then I updated it as before and somehow wound up with Malwarebytes Anti-Malware (Trial) After that I noticed my system response had degraded. About one hour after rebooting my system, I ran Windows Task Manager and noted the following for mbamservice.exe: CPU - Hovering near the top at 10% CPU Time - Highest accumulater at 0:10:00 I/O Reads - 2,472 (Increasing slowly) I/O Writes - 59 (Static) I/O Other - Highest at 18,000,000 (Increasing fast) Mem Usage - Second highest at 170,000 (Static) Page Faults - Third highest at 1,000,000+ (Increasing) Currently, the program does not appear to be degrading my system. However, if I find out later that it is affecting system response, I may de-install it.
I upgraded to the paid version and it has actually dragged my computer processes down to a crawl. I have no idea why the paid version has managed to completely lag an i7 with top performance speed and ratings. I cant even get browsers to load at times. This is horrible and I cant believe I paid money to do this to my computer.
My computer is very slow now. CPU is running and I have no idea what's going on.
Is a reputable malware protection program, but in my opinion uses too much memory

Best practices for resolving mbamservice issues

A clean and tidy computer is the key requirement for avoiding problems with mbamservice. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the mbamservice.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
