Malwarebytes "skips" about 25,000 objects when scanning

[NotAvailable98]

Hello,

this is my first time here so I hope its the right place and section.

I noticed something weird in Malwarebytes (free) when I scan. I start the scan (full or quick) and it starts normally, and after a few seconds when it gets to about 900 object scanned, it suddenly "jumps" to about 25,000 objects. iI happens when it scans something in System32, objects are different, it's not always the same file but it is System32 and about 900 objects.

I don't know if it is normal, it doesn't happen to me on other computers. I don't get any errors, I don't notice any problems or issues in my system, but this is strange - a full system scan is completed within less than 20 minutes! and I'm using about 100GB of space! (I have 500GB HDD if it matters).

What I tried so far:

1. Re-installing

2. Checked C drive for problems (non detected)

3. scanning in safe mode

Always the same thing. Could it be because C drive is "indexed" in windows for faster searches?

This maybe isn't a major problem, and I believe my system is not infected (I hope so...) but it bothers me because it makes the program useless and I really like it as an additional anti-spyware, and I scan my system occasionally.

Any help will be greatly appreciated.

Many thanks!

This is quite normal, it's checking registry items during a certain phase of the scan near the beginning, which goes very quickly and causes the number of objects scanned to jump significantly in a short amount of time.

Also note that if you perform a scan after having already scanned previously with Malwarebytes and haven't rebooted in between, that your subsequent scans will be much quicker thanks to disk caching (it has already read all of those files, so scanning them again goes much faster).

Thank you very much!

I noticed this issue first time when I did a full system scan in safe mode, after a scan with Norton Internet Security 2012, So it's not disk caching... Is it normal that this full scan lasted only 20 minutes? That's the strange thing... I'm using almost 100GB I think a full scan should last longer.

Thank you.

Scans will generally be faster in Safe Mode, simply because there are far fewer process running, also keep in mind that much of our deeper scanning technology does not function in Safe Mode, so there are infections that cannot be detected in Safe Mode with Malwarebytes that can be detected when scanning in normal mode.
