Exclude and Trust Malwarebytes Anti-Malware Files and Processes
Most antivirus and firewall software includes self-protection or tamper protection. With tamper or self protections enabled, the access to any protected or locked files in antivirus or firewall programs is prevented. Most antivirus software does not allow opening or accessing the quarantined items, except using its own quarantine manager. Also, an advanced firewall and antivirus program will prevent unauthorized changes made to the operating system or important programs. This is to prevent unwanted injection or modification in the critical system files or applications.
When you run a full system scan using Malwarebytes Anti-Malware, the scanner will run a deep system scan including the quarantine directory of the antivirus program and because of this, the antivirus program will prevent Malwarebytes from continuing what it is currently doing - to scan the contents of the quarantine folder which are locked and protected files. When the self-protection of security programs has prevented Malwarebytes from scanning, Malwarebytes quits scanning and the program will stop working. You will receive an error message such as:
"Malwarebytes' Anti-Malware has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available."
"Malwarebytes' Anti-Malware has stopped working. Windows can check online for a solution to the problem."
To resolve the problem, you need to configure your antivirus and firewall software to exclude and trust the files and processes of Malwarebytes.
Look for the exclusion or ignore list option in the installed antivirus software and then add the following files as excluded, allowed or ignore list:
mbam.exe, mbamgui.exe, mbamservice.exe, zlib.dll, mbam.dll and mbamext.dll - Located in the C:\Program Files\Malwarebytes' Anti-Malware folder.
mbam.sys and mbamswissarmy.sys - Located in the C:\Windows\System32\drivers folder.
If you are using Windows XP, add rules.ref in the exclusion list of your antivirus program. It's located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware. For Vista and Windows 7 users, rules.ref is in C:\ProgramData\Malwarebytes\Malwarebytes' Anti-Malware
If you are using a 64-bit edition of Windows to exclude the above files then it is located in C:\Program Files (x86)\Malwarebytes' Anti-Malware and C:\Windows\SysWoW64\drivers folders.
If you are using advanced firewall software, configure the program control or firewall rules to allow Malwarebytes to use the Internet connection. End-users of Internet Security suite software should do the same by adding all of the above files in exclusion lists and at the same time, allow Malwarebytes program to connect to the Internet as trusted program.
