MBAM V2 scan time MUCH shorter than 1.75

[McAlex]

Before upgrading to MBAM V2 (free version) my PC needed a full scan time of more than 2 hours, and scanned over 500,000 objects.

Now, with the latest V2 my PC runs only 10 minutes and scans just about 300,000 objects.

 

Can I trust this MUCH shorter scan time ?  --  It's so fast, almost too nice to be OK !?

Thanks for your reply.

Hi:

 

I suspect that you might be comparing an apple and a banana.

 

The different types of scans were renamed in version 2, and it has caused a bit of confusion.

"Flash" is now "Hyper"
"Quick" is now "Threat"
"Full" is now "Custom"

Hyper scan is available only to paid, PREMIUM users and is not routinely needed or recommended -- if anything is found, a subsequent Threat scan will be needed anyway.
THREAT scan is the most important and most useful scan -- it is the one that ought be run on a regular basis (daily is the default setting now in 2.0).
Custom depends on what drives, folders and files are selected -- routine use of a "full" system scan is neither necessary nor recommended, as it's a task better suited to your antivirus.

As far as scan times, version 2.0 is more powerful and more thorough than version 1.x.
Scans may take a bit longer -- that is normal and nothing to worry about.

Thank you for the fast delivery of the apples and bananas !

 

Sorry, I forgot to mention that with new V2 I used the (default) THREAT scan.  That makes a comparison between almost the same size apples, I guess !

 

You said at the end of your reply that V2 "equal" scan should be a bit slower, which I appreciate, as V2 does more.

But now I am double worried with the shoddy 10 minutes !  --  What could be wrong ??

Thank you.

Hi:
 
Apples to apples, then, I guess.
(A lot of folks think that "Threat" is the old "Full", or that "Hyper" is the new "Quick", etc.).
 
Anti-Rootkit (ARK) scanning is a new feature in 2.0.
It is disabled by default.
Enabling it does tend to increase scan times because of how it works.
The same is true for archive scanning -- enabling it will increase scan times, while disabling it will speed things up.
 
OTOH, overall, the 2.0 engine is more powerful.
 
There are MANY factors that determine scan times:

Size of disk
Disk type
Disk speed
Disk caching
CPU speed
Controller type and speed
Operating System used
Amount of files (including temp files!)
Amount of folders
Amount of archived files such as zip, rar, sfx, etc. (if this is enabled)
Rootkit scan or not (if this is enabled)
PUM/PUP scans
Other security programs running at the same time that may potentially be monitoring all file accesses by any other process.
Drive integrity - if a drive is failing it can take a long time to ignore and bypass sectors on a disk or simply fail period and hang the scan.
Other ongoing disk I/O processes
System being infected can also affect speed of scans
Also note that changes in the MBAM database can also cause scan times to increase or decrease, so that's another factor to consider, as mentioned => HERE <=
 
So, the bottom line is that it's probably nothing to worry about -- you may have cleaned temp files, or deleted archives or somehow altered one or more of those factors.

 

We have folks complain that scans are too slow, and others complain that they are too fast.

If you want, post back with one of your Threat scan logs and folks will take a look at it.
 
If you want to undertake some basic troubleshooting, here's how:

• Please uninstall your current version of MBAM and reinstall the latest build - MBAM Clean Removal Process 2x
• If that does not correct the issue, then please read the following and post back the requested logs - Diagnostic Logs
• NOTE: There is an FAQ section with valuable information located here - Common Questions, Issues, and their Solutions

Thanks!
