# Website Protection slows computer

## Recommended Posts

On one of my test machines I have noted that when Malicious Website Protection (MBAM Premium 2.1.8.xxxx) is enabled, the machine slows to an unusable crawl.

As this machine is only used for testing purposes it is not that important but if there is a simple solution then I will apply it - if not that is also OK.

The problem is not related to the Internet connection.  This machine is connected to a very fast Broadband service.

The AV product on this machine is Avast.  Monitoring Task Manager does seem to indicate that there may be some conflict between Avast and MBAM in terms of resource usage when MWP is active.

Hello,

You might want to try setting mutual exclusions between MBAM and your AV.

Malwarebytes Anti-Malware is not meant to be a replacement for antivirus software. Malwarebytes Anti-Malware is a complementary but essential program which detects and removes zero-day malware and "Malware in the Wild". This includes malicious programs and files, such as viruses, worms, trojans, rootkits, dialers, spyware, and rogue applications that many antivirus programs do not detect or cannot fully remove. It is important to note that Malwarebytes Anti-Malware works well and should run alongside antivirus software without conflicts. In some rare instances, exclusions may need to be set for your specific antivirus product to achieve the best possible system performance.

For 32 bit versions of Windows XP, Windows Vista, Windows 7 & Windows 8:

• C:\Program Files\Malwarebytes Anti-Malware\mbam.exe
• C:\Program Files\Malwarebytes Anti-Malware\mbamdor.exe
• C:\Program Files\Malwarebytes Anti-Malware\mbampt.exe
• C:\Program Files\Malwarebytes Anti-Malware\mbamservice.exe
• C:\Program Files\Malwarebytes Anti-Malware\mbamresearch.exe
• C:\Program Files\Malwarebytes Anti-Malware\mbamscheduler.exe

For 64 bit versions of Windows Vista, Windows 7 & Windows 8:

• C:\Program Files (x86)\Malwarebytes Anti-Malware\mbam.exe
• C:\Program Files (x86)\Malwarebytes Anti-Malware\mbamdor.exe
• C:\Program Files (x86)\Malwarebytes Anti-Malware\mbampt.exe
• C:\Program Files (x86)\Malwarebytes Anti-Malware\mbamresearch.exe
• C:\Program Files (x86)\Malwarebytes Anti-Malware\mbamservice.exe
• C:\Program Files (x86)\Malwarebytes Anti-Malware \mbamscheduler.exe

Note: If you are using a software firewall besides the built in Windows Firewall, you'll need to exclude MBAM.EXE, MBAMSERVICE.EXE and MBAMRESEARCH.EXE from it, as well.

Note: Once that's done, please make sure that if either of those programs has any sort of web filter, that you add the following as a trusted site:

`data-cdn.mbamupdates.com`

After doing this, you could add Avast in MalwareBytes exclusion list similar like on the picture below:

Apologies for the delayed reply - it has been one of "those" weeks.

Thanks for the very detailed information... ...  I will try your suggestions over this weekend and will report back early in the new week.
