Windows 7: MalwareBytes 2.0.1 taking forever to scan

Windows 7 Ultimate X64 SP1

Since MBAM is not a full blown AV program I'd expect it to scan much faster. Even given all the "reasons" of slower than cold molasses scans, 1.75 does a lot better, not good, but better.

For comparison, Norton scanned 842,615 items, MBAM only 334,718. Norton took 18 minutes, MBAM 2+ hours.

Not a good sign,
Not sure what you mean by that.
MBAM never was an antivirus.
Wasn't meant to be.
It's a specialized tool designed to run alongside an AV to provide layered protection against zero-hour and zero-day threats often missed by AVs.
It is designed to catch live infections on the boot drive.
Flat file scanning of an entire system is fine once, upon install.
But if you want to scan an entire system with multiple local or NAS drives, looking for dead remnants of old infections, then an AV with a ginormous database of 10-years' worth of infections is better suited to the task.

[quote name="AdvancedSetup" post="816703" timestamp="1397181686"]

Use Threat Scan. That is the equivalent of the previous Quick Scan.
We added the Full Scan (now Custom Scan) due to many complaints from users wanting to scan all files even though we've told them many times that their antivirus is much better at non active threats on a flat file scan. The new 2.0 includes a rootkit scanner but unless you're going out to very risky sites and downloading cracked software all the time then once you've done a rootkit scan once and a Custom/Full Scan once there really is no need to do one again unless there is really some reason to cause you to believe that something did get past your security and get onto the box. Doing a rootkit scan daily or a full scan daily is certainly going to place more stress on your hard drive and if its an SSD then that could potentially greatly reduce the life expectancy of the drive.
As for slower ARK scanning "causing more harm than an infection", I really wouldn't know what to say.

The constant reminder of mabm not an antivirus is unnecessary,
I believe we all know that very well,
Personally I've known this for over four years

Clearly choosing the Rootkit option during a full scan is the biggest mistake to repeat,
Knowing what I do now "ever even using at all"
There should be nothing wrong with repeating a full scan weekly or bi-weekly as a damaging process,
If it is then the product is the problem not the habit of running a full scan without rootkit included.

The developers at MBAM are surely hearing about all the freezing/slow scan issues. Hopefully they know how to fix 'em.

I believe I used the word "wear" and AS used the term "stress" (esp for SSD).
That would be true of any security program scanning a drive repeatedly.
Neither of us called it "damage".

But, I'm not here to argue.
I am just a lowly home user and was just trying to help.

You win!

Wow, 23+hrs :-(
Thanks for the info. I won't be trying the rootkit option again. Like the video there were many hangs and freezes it seems, (now that I know what they were. It's like it kept stopping the scan for 10 to 20 seconds and then the file counter would increase by about 12 to 15 files).

I'm going to run a full custom scan again on just my system and program drives without the rootkit scan enabled and see what happens.

Unfortunately the only repeated response has been use the threat scanner instead,

Seeing if that's mabm's position the full scan option should disappear after using it once
1.75... has the rootkit option in more tools,
I've never used it or any of the More tools,
Now I see why = beta,
I had a pretty lame correspondence with mabm's email support,
All I got was mabm fine I still don't think they realize the logs were from 1.75...
I believe their new policy is to dump actual customer support for pro licenses and keep repeating the same non-sense if it freezes don't use it but once,
If it freezes once then never use it again = Threat scan/ Threat scan/ Threat scan....... blah......

Bingo, although the instance was a bit different the result was identical,
We have experienced major stability issues on Windows 8.1 and Windows 7. It frequently got stuck in a loop when we attempted to scan a folder via the context menu entry, failing to overcome the pre-scan operations phase. Our attempt to cancel the task was in vain, and we had to terminate Malwarebytes' process.
According to mabm they have hopped-skipped- and jumped to avoid this issue completely without even acknowledging it via my email communications,
After reading the logs they requested they closed the ticket, mabm is okay,
And said if I have anymore questions contact them
Nice support.

If you wish to run a full scan 10 times a day please be my guest. No one is saying you cannot run one if you want to. I said I find that for myself it's not needed.

Are there issues with the latest version - yes. Are we working on them - Yes. Did you participate in the Beta and voice your opinions then before release - No.

Our forum has probably just a tad more information and support available than here and where I would recommend you actually seek support, but that's up to you as well.

I'm not here to argue either. If you want help come get help - we're certainly willing to help.

Thank you.
