Reluctantly, I have had to remove MBAM's resident protection from my PC, and re-instate Windows Defender real-time protection.

Ever since enabling MBAM's protection, I have experienced progressively worse slowdowns in opening apps or folders, particularly "My Computer", "Outlook Express", desktop IE7 links, etc. Some folders/apps take up to 5-10 second to open. The longer my Windows session between reboots, the worse the problem. Eventually, when I click on "My Computer", I get the "searching flashlight" for many seconds before it opens:


Apart from MBAM, the only programs I load at Startup are:
NOD32 2.7
Comodo BOClean 4.25
Comodo FW Pro 3.0

By trial and error, I have eliminated NOD32 and BOClean as the source of this slowdown, by disabling them from startup. Disabling MBAM protection definitely solves the problem. Enabling Windows Defender real-time protection does not result in this slowdown problem. This is highly reproducible on my XP MCE system.

Just FYI.

You can't use Comodo's BOClean and the real-time protection in Malwarebytes' Anti Malware at the same time. Only keep one of them (since you paid for Malwarebytes, then I imagine you'll want to stick with it).

Also, you may want to disable the Defense+ feature of Comodo Firewall Pro v3.0 if you are still experiencing slowdowns after removing BOClean.

Joe was a beta tester that received a free license .

Have you seen this issue before 1.07?

[joe53]

Marcin, I can't say for sure when this started, but it pre-dated 1.07. It certainly wasn't apparent with v1.0, but I noticed it a few weeks ago, and it's been getting progressively worse.

I certainly ruled out BOC, since the problem persists even when BOC isn't loaded. It might well be related to some conflict with CFP 3.0, or its D+ module, both of which I'm reluctant to disable, since they have been trouble-free otherwise. There haven't been any updates to CFP in the last few weeks that I recall, though.

Even opening MCE to watch TV displays this lag when MBAM's protection is enabled; maybe it is specific to my OS, since I've never seen this behaviour before.

I will point Mahesh toward this thread. Any other information you can post would be great.

[AdvancedSetup]

How much CPU/RAM is MBAM using when the system is being slowed?
Are there any RED or YELLOW error message in the Event Viewer?

This is probably not related but could potentially improve your speeds when opening My Computer

Open Explorer, go to Tools -> Folder Options and click on the View tab. At the top of the File and Folders list, uncheck "Automatically search for network folders and printers" and click OK.

You've tried uninstalling BOClean and restarting your computer? BOClean has a kernel module that runs even when BOClean itself is disabled and not running, so the problem could still be a conflict with that.

[joe53]

Thanks to all for the suggestions.

GT500:
I uninstalled BOClean and rebooted, but the problem persists, with only MBAM, my FW and AV running. Disabling MBAM protection continues to solve the problem.

AdvancedSetup:
MBAM uses about 40-50% CPU when this problem happens.
Unchecking that Folder Option you suggested made no difference.

Further info:
Since uninstalling BOC, I'm experiencing a 5-15 second lag opening some programs/folders for the first time after a reboot. Thereafter, they open without problem, so things are somewhat better. I also see this lag the first time I right-click on a file to open the context menu, but not thereafter.

[Scavenger]

I must admit the last couple of times i had BOClean installed i got the same troubles. Can you restore to a date when boclean wasn't installed yet?

I don't even notice i got MBAM installed here.

Joe, Mahesh wants to know whether there are any odd event log entries with anything pertaining to our program.

[joe53]

Nothing seen in Event Viewer recently, but I did find numerous entries from Feb. 24:

Event Type: Error
Event Source: MBAMService
Event Category: None
Event ID: 1
Date: 24/02/2008

Description:
The description for Event ID ( 1 ) in Source ( MBAMService ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: MBAMService, Error: Monitor::ScanDLL failed.

Sorry to say, but 1.08 slows my wife's system down as well. Latest XP, Nod32, Superantispyware 4, and Winpatrol.

Firefox took 35 seconds to launch. Usually it is 2 or 3 seconds. MBAM program took almost 20 seconds to launch.

Uninstalled and reinstalled program with same results.

Dang.

Followup: Just uninstalled MBAM and reinstalled BOClean. Restarted. Firefox took 7 seconds to launch--not quite the 3 seconds I estimated, but quite a bit faster than 35 seconds.

[RubbeR DuckY]

Zachary, NOD32 or SAS4 use kernel level hooks and may also be impeding on the speed of the system. So far the best protected and quickest systems we have used were MBAM with AntiVir. We are still working on compatibility issues and speed increases. Should have some better results in following releases.

Joe, Mahesh is looking into that error.

I 100% believe that and am still a happy purchaser in spite of this temporary hiccup. Your integrity and dedication are what impressed me enough to buy two copies so far.

I use NOD32. After I activated real-time protection with MBAM, I found that the initial launch of Firefox, Thunderbird and some other programs was slow (7-10 seconds). This didn't affect all programs (e.g. MS Office was unaffected). Subsequent launches of the programs were back to normal speed. After a reboot the initial launches were, again, slow. During the delay, the CPU use is nearly 100% - shared between NOD32 and MBAM (60/40).

I've not got a problem with this, as it only occurs after a reboot, but I thought that the info' might help.

[GT500]

I wonder if it's a conflict between NOD32 and MBAM while the applications are being cached in the prefetch? Do you have something set up to delete the prefetch on reboot/shutdown? If not, have you tried booting in Safe Mode, deleting your prefetch, and seeing if other applications experience the same issue after a reboot?

[beynac]

I don't have anything which clears prefetch on reboot/shutdown. I've tried restarting with prefetch "as is" and with it cleared before reboot. There doesn't seem to be any difference.

As I said, I'm not worried by this delay. It's not a long one and only happens when I start up the computer in the morning. I only posted about it because I thought that the info' might help with the OP's problem.

I am experiencing the same issue on Windows XP SP3. I purchased after being a semi-frequent user, but now the protection module is virtually useless since I cant run it without effectively freezing my machine. I installed all other virus protection programs so no other anti-malware/adware/virus software is running.

Do you know what other applications you have starting up with Windows?
