Unable to turn on real time web protection

[DavidMusgrove]

Hi

 

Since upgrading my wife's laptop to v3 etc. , I have ben unable to turn on real time web protection. When the tool is first installed it shows web protection as being on, but as soon as I enter my ID and key, it no longer keeps web protection on. I have done numerous uninstalls and cleans and then reinstalls of various versions of MBAM, with no change to the status of the real time web protection. Have tried turning it on manually, disabling anti virus , all with no effect. I attach the requested files for diagnosis below. Thanks :-)

There is a required service called BFE that is not running on your machine. This fix from Microsoft should fix the BFE service. Please run the fix and then try to start Web Protection

Hi - thanks to you both for trying to help. I ran the Microsoft fix and it could not fix it ( attached ), and also tried to service manually under administraot to which I got an Error 5.

Sorry!

OK, let's try combofix as this should be able to fix it.

Download ComboFix.exe from here http://download.bleepingcomputer.com/sUBs/ComboFix.exe and save it to your desktop.

Next, disable your AntiVirus and AntiSpyware applications as they will interfere with the tool and fixes that may need to be done. 

Double click on Combofix.exe and follow the prompts.  During the course of the scan your desktop may disappear - this is normal, and it will return.

When finished, it shall produce a log for you.  Please **attach**  the C:\ComboFix.txt to your next reply for further review.

NOTE: If you encounter a message "illegal operation attempted on registry key that has been marked for deletion.." and no programs will run - please just reboot the machine and that will resolve that error.

Also please provide an update on machine behavior.

Thanks for this. I did a full backup, ran comboix which took about 15 minutes to complete and after rebooting it seems to have fixed the issue.

I attach the logs and some screenshots. May I ask why it didn't work before and what combofix has sorted as as a total amateur I have looked at the combofix log and it doesn't say what it fixed or what was in error.

 

Thanks

The Base Filtering Engine (BFE) service is used by a lot of different Windows components. Without that service running, it was stopping web protection from working properly. It's hard to say exactly what caused that issue, although infections are known to break this key to make windows applications not run properly. You may want to run a threat scan on your machine just to be sure you don't have any infected files. Other than that, it's going to be very hard to determine what caused that service to fail, but it's a good thing you got it working!
