Malwarebytes not responding after several minutes


Recommended Posts

Hello,

After several minutes or scanning, Malwarebytes goes non-responsive. When it stops responding, the screen is similar to this

Objects Scanned: 30648

Objects Infected: 2

Time Elapsed: 3 minute(s), 5 second(s)

Currently Scanning:

c:\Windows\system32\Config\SECURITY.LOG1

It usually stops on SECURITY.LOG1, but not always.

I am pretty sure that my laptop is infected because I had to rename the executable just to get it to run. I followed the procedure below that I found on this forum because I thought my Norton Anti-virus was preventing it from running. Still will not run. I also cannot install HijackThis because as soon as I try to install, I get a BSOD.

OS=Windows Vista Home premium

Thinkpad T61.

Any guidance is appreciated.

Thanks,

Ron

Basic procedures to correct freezing issues often due to other Security Software

If these procedures do not correct the problem please create a new post seeking further assistance

1. Uninstall Malwarebytes' Anti-Malware using Add/Remove programs in the control panel.

2. Restart your computer (very important).

3. Download and run this utility.

4. It will ask to restart your computer (please allow it to).

5. After the computer restarts, install the latest version from here

Note: If you're using a PAID version of Malwareybtes, you will need to reactivate the program using the license you were sent via e-mail.

BEFORE registering and starting the Protection Module, locate the Exclusion List for your Anti-Virus. Probably under an advanced menu in the program.

Add the following folders, sub-folders if you can, at a minimum add the files to the exclusion to be safe.

* C:\Program Files\Malwarebytes' Anti-Malware

* C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware

* C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\rules.ref

* C:\WINDOWS\system32\drivers\mbam.sys

* C:\WINDOWS\system32\drivers\mbamswissarmy.sys

* C:\Program Files\Malwarebytes' Anti-Malware\mbam.exe

* C:\Program Files\Malwarebytes' Anti-Malware\mbamgui.exe

* C:\Program Files\Malwarebytes' Anti-Malware\mbamservice.exe

Is this during a full scan or quick scan? If full please switch to the default quick scan.

Malwarebytes does not recommend full scans to search for malware. Our quick scan is designed to find all the places malware loads in memory and hides from conventional scanners.

There are any number of reasons a scan will hang, freeze, appear to stop or take different lengths of time to complete, including file\folder content, other security software quarantine files, amount of user accounts and more.

We're constantly working to improve the full scan parameters on some systems which exhibit this hanging issue.

When\if this issue is resolved 100%, we will still continue to recommend quick scans as the best way to detect malware.

Hello,

Just an update, I can get malwarebytes to run in Safe mode and also if I go into MSCONFIG do selective startup and disable all non-Microsoft services. The first time I ran it after disabling the services, it detected and cleaned 5 problems, and another c:\Windows\System32\MSIVXcount (Trojan.Agent) was put on the delete on reboot list. I rebooted (still using selective startup) and ran malwarebytes again. This time it still found Trojan.Agent and again added to the delete on reboot list. I changed back to normal startup, and after reboot got a message that Trojan.Agent was deleted. I ran malwarebytes in normal startup mode, it detected 3 additional problems which needed to be deleted on reboot. Rebooted again in normal mode, reran malwarbytes and now runs clean with no problems detected. I'm not sure what was initially preventing malwarebytes from running in normal startup mode, but bottom line I guess is that you just have to keep on trying.

Thanks,

Ron

Malwarebytes Anti-Malware is not designed to find malware in safe mode. Doing so gives malware a chance to hide and subsequently, can be missed when you do scan. We need to have all parts of the malware to load in order for Malwarebytes Anti-Malware to find it and delete it.

Sounds to me there may be an issue with one of the many things you disabled. Can you enable each one to trouble shoot to see which one causes the problem?

I also suggest you post the scan log as well for us to review.
