i am using Windows XP Service Pack 3 Service Pack 3 32 bit Operating System and Malwarebytes Anti-malware (Premium) 2.0.1012 Here is what i found out the problem: When i am using Google Chrome (36.0.1985.143 m) and once moving the cursor on the page, mbamservice.exe will be kept running and leads to CPU at 100%. The browser is very very slow. However, when the cursor stays (no move), mbamservice.exe becomes zero and the system idle process is about 98%. Then i try to use IE8, mbamservice.exe remains very stable. (almost no usage of CPU at all). There was no such problem in the old version. I have read some of the similar topics and also uninstalled the current version of MBAM by MBAM Clean Removal Process 2x and reinstall the latest build. However, it is still not working.
