Please can you clarify your issue? Is only the MBAM window becoming unresponsive, or the whole of the OS/any running web browser(s) too? If the latter, I have the exact same issue with both the OS shell (taskbar/notification area icons) + web browser both becoming frozen/locked up and unresponsive, during the Pre-Scan phase of MBAM Scan.

Thanks for the explanation! I just posted the logs in a new thread the section you specified. You are welcome.

Originally posted is another section. Was asked to post here now, so doing that. ----> This is not good. I have a fast and powerful PC - Intel Core i7 CPU, 32 GB of RAM (4 sticks 8 GB each), NVidia GeForce GTX 670 videocard, 2 SSDs, and also a 4 GB RAM disk. When I do a scan with the new MBAM 2.0 version (using the free one), the MalwareBytes Antimalware Pre-scan causes the Windows shell and my web browser to stop responding (Chrome says Not responding, Windows taskbar won't respond to clicks). The mouse (by Razer, USB wired) won't reply to clicks also and barely moves or does not move at all. Keyboard (HP, again USB) also fails. Any comments on this?Versions 1.x of MBAM Free never did this. Using Windows 7 64-bit Ultimate, SP1 + all Updates installed. Using the free MSSE antivirus by Microsoft as main antivirus software.I have Daemon Tools Lite, version 4.49.1.0356, but without the SPTD component. Also, my RAM disk software is from AMD.I have an additional USB 3.0 Etron 188 chipset PCI Express card (4 port), because my ASRock motherboard only has two USB 3.0 ports.I also have VMware Workstation 10 installed, as well as LogMeIn Hamachi, maybe those two could affect Malwarebytes Antimalware with the extra (virtual) network cards they create. If you need more info on my config, please tell me. Attaching log files from 3 different tools - DDS, Mbam-Check, and FRST. CheckResults.txt attach.txt dds.txt Addition.txt FRST.txt

You are telling me to post in the Malware Removal forum - do you mean to say my PC has malware/virus(es)/trojan? OK, will post there now.

3rd tool log files, attached. Addition.txt FRST.txt

2nd tool log results, attached. CheckResults.txt

OK, I tried my best to remove any. New logs attached. If there is still any bad software, please tell me which other one(s) you want removed. attach.txt dds.txt

Any update on my issue?

Hmm, was not the Edit function available to posters with 50 posts? If it is 100 posts now, I guess even with the 50 post limit there were abusive users, so you had to up the number from 50 to 100.

Yes, restarting the PC does not help any. Another detail that might help (or not) - when the MBAM scan causes Chrome to stop responding, for a moment (2-3 seconds) Chrome shows/appears to be using just ONE tab - the currently active/open one. Then the system gets "unstuck" and Chrome goes back to showing all open tabs (for example, 5-10 of them). I am able to change the tab and get this "frozen" situation on different Chrome tabs in one MBAM scan.

Here are the last log files, from the 3rd tool, attached. When will I be able to edit my posts? Do I need to reach 100 posts for that? Addition.txt FRST.txt

Here is the log file from 2nd tool, attached. CheckResults.txt

As noted in my original post, I am on Windows 7 64-bit. OK, it finally finished. Attaching the two files from DDS.scr. Will run the 2nd tool now... attach.txt dds.txt

Sorry for very slow reply, was a bit busy. How long does DDS.scr take to run? 5 minutes, 10, 20+, 30?

Please can you clean up the thread and remove all posts starting from 5th one and up to your own ones?

Just tried it. Cleaned, restarted the PC, installed MBAM Free 2.00 version again, updated to latest defs, tried a Scan - still freezing. Any other suggestions? Using the free MSSE antivirus by Microsoft, by the way.

Thanks for the reply. Yes, I did. I want to do this right the first time - do I run the Removal tool directly, OR do I uninstall MBAM 2.0 from Windows 7 Control Panel, then run the Removal tool?

Ooops, several more pieces of info on my config - I have an additional USB 3.0 Etron 188 chipset PCI Express card (4 port), because my ASRock motherboard only has two USB 3.0 ports. I also have VMware Workstation 10 installed, as well as LogMeIn Hamachi, maybe those two could affect Malwarebytes Antimalware with the extra (virtual) network cards they create.

Similar problem - on my Windows 7 64-bit Ultimate SP1 PC, a MalwareBytes Antimalware 2.0 version scan causes the PC to temporarily freeze. I don't get and flickering, however. Also, I can do scans many times, they don't fail - they just cause the PC to lockup/freeze in the Pre-scan phase of the scan.

Forgot to mention - is this a known issue? Has anyone before me reported anything similar? One software detail I forgot is I have Daemon Tools Lite, version 4.48.1.0347, but without the SPTD component. Also, my RAM disk software is from AMD.

No problem on the posts issue. It just seems to be this makes MalwareByte look bad, because VirusTotal reports the virus/trojan as undetected by it. Also, will MalwareBytes clear & stop the trojan completely? I mean stop any active EXEs, remove Registry entries/etc? I am testing the svhost.exe removal with it being inactive, for obvious reasons (when it was active, the trojan maker started editing my files ).

Why can I still not edit my posts? You said 10 posts will remove this limit. Anyway, this trojan signature (plus possibly the Registry entries it creates on infecting a system) should be added to your definitions! All of your major competitors detect and clean this trojan, with the sole exception of "Avast!".

Is there a way to add the file to the MalwareBytes proper definitions, so that it can catch it without any heuristics? By the way, since my antivirus software - Microsoft Security Essentials - catches and removed this trojan, I have to disable it first, then test with MalwareBytes. Do you want the file itself too? It is a very dangerous trojan.
