I have been using the program both free and paid versions with no complaints for several years.

I do have one question though what the heck is pre scan operations

Hi:
 
As with any security program, MBAM needs to do a bit of "housekeeping" before a scan (check for database updates (so it will have the current version), enumerate files to be scanned, load the database, etc.).

 

More info about v2.2.0 HERE; User Guide ONLINE; User Guide PDF; FAQ: Common Questions, Issues, and their Solutions

 

Hope this helps,

 

MM

Thank you both. That is sort of what I figured was going on but I noticed like a few others in MBAM's forum it took a while.

It actually takes on average 20 seconds longer than it does to update the definitions alone.

Everyone's system is different so time will vary with each.

The speed and ability to complete an anti-virus or anti-malware scan depends on a variety of factors.
  • The program itself and how its scanning engine is designed to scan: using a signature database vs heuristic scanning or a combination of both.
  • Options to scan for rootkits, adware, riskware and potentially unwanted programs (PUPS).
  • Options to scan memory, boot sectors, registry and alternate data streams (ADS).
  • Type of scan performed: Deep, Quick or Custom scanning.
  • What action has to be performed when malware is detected.
  • A computer's hard drive size.
  • Disk size and used capacity (number of files that have to be scanned).
  • Types of files (.exe, .dll, .sys, .cab, archived, compressed, packed, email, etc) that are scanned.
  • Whether external drives are included in the scan.
  • Competition for and utilization of system/CPU resources by the scanner.
  • Other running processes and programs in the background.
  • Whether the scanning engine stalls, hangs or freezes.
  • Interference from malware.
  • Interference from other security programs attempting to scan at the same time.
  • Interference from other programs attempting to update (download/install) components from the Internet.
  • Interference from the user (whether or not you use the computer during the scan).

I couldn't have said it better myself.
Because I did (@daledoc1 is my alter-ego at MBAM forum).
 
<LOL>

Actually, that sounds quite normal.
With MBAM 2.2.x (even the Free version), database updates are incremental (unless it has been a long time since the last update). So, database updates can be quite fast, especially if the database has been recently optimized (as it was on Oct 13) and if a database update had been performed on this same system not long ago.

When you start a scan, even a scan of a single file via the explorer context menu, MBAM still has to load the entire database before it scans. That can take some time, as mentioned in the thread at MBAM forum here and in the comprehensive list of factors that @Quietman7 mentioned.

 

Cheers,

The 20 seconds time differential was between loading new spyware definitions and pre scan operations not the whole scan just to clarify. The explanations of time difference is still good and valid.

Just a bad habit carried over from the old days when I did a good bit of Beta testing. I always watch time with a stop watch when a program runs. LOL Time it takes to complete one part from another part.
Often really does not mean much.

And to add:

 

With MBAM Premium, database update checks and scheduled scans can be configured to run silently from the system account.

 

So, there's seldom a need to run a manual scan or to obsess over "scan times" or "pre-scan operations" (although some users do seem to care about a second here or there, for reasons I've never quite understood).  :wink:

 

Cheers,

I wasn't aware of that...neither Ron, Bob, Rick, Pete or anyone else ever mentioned it. :)

No problem. :lol:

I was just teasing you.

 

(And it's good that you provided the link to that thread, as it includes an "official" reply from Becky (@bdubrow), the MBAM Senior Technical Product Manager.)

I come from a generation of users who actually expected something for our money or we didn't spend it developers started paying attention to what the users wanted and expected for their money.

A few seconds can mean a great difference in a system that operates in Milliseconds.
That's a 1000 operations per second 20 seconds is almost a lifetime LOL.

Too bad Microsoft itself could never get a Windows computer to fully boot in milliseconds. :wink:

Too true quietman7 or much of anything else for that matter.
While the processor can process at that speed the rest of the system can not due to hardware and just physical limitations of the system.

Not really a fair comparison on my part actually. One can not break the laws of physics, bend it some but not break it.
