I intaled a Paid Version of "Malwarebytes" on a "Dell Xeon 470 Workstation" yesterday.
The first time I ran a scan it took over 2hrs which is fine by me.
Today when I did a Full Scan it only took 49 seconds.
Figuring it was a glitch I waited a few minutes and tried again it still took 49 seconds.

Is this too fast? Am I missing something? If a Full Scan takes 49 seconds how long does a Quick Scan take?

Thanks

I think is no right for both, 2 hours or 49 seconds is not real, on my notebook, hard disk 80 gb, free for 70% the full scan lasts almost 30-33 minutes, the quick scan about 5 minutes.

49 seconds seems a bit fast for a full scan Maybe try running MBAM with the /developer parameter and pasting the log so the developers can take a look

Mystery Solved.

I am using a Dell Xeon 470 Workstation with Two Hard drives.
For some reason I was only scanning the hard drive with the least amount of data on it.

Thank You !!!

PS

Scanning is now taking 2hrs 4minutes.

Wow when I had MBAM on my system before and had it check EVERYTHING it was at like 1 million plus files and 17 hours and was still going....wow

The full scan is very thorough, but 99.99% not necessary.

I'm presently at 2 hours and still running. There's definitely an exponential slowdown in the scan as time goes on - the longer into the scan the slower it takes. It's current scan rate is approximately 3 files per second. Something is not right here.

Disregarding the possibility that an infection itself may be causing the computer to become progressively slower, start with simple stuff.

How much RAM do you have?
What size is/are the hard drive(s)?
What is your CPU speed?
What is the architecture?
How fast do your hard drives spin?

On this computer a "full scan" takes me about an hour-and-a-half (not just the first time):
2 GB RAM
AMD Athlon XP 2400+ 2.0 GHz
40 GB 1st hard disk drive, 5400 rpm
32-bit
120 BG second hard disk drive, 7200 rpm

On this one, in spite of the large disks, it only takes about 20 minutes!
4 GB RAM (incorrectly identified in another post as 8!)
AMD Athlon 64 X2 Dual Core 5200+ 2.71 GHz
64-bit (but running older 32-bit XP)
300 GB 1st hard disk (210 GB not used for Windows, so effectively 290), 7200 rpm
500 GB 2nd hard disk, 7200 rpm

No infections for nearly 2 years

I apologize for jumping out of line, but the opportunity to go straight to the head man was too good to pass. My QUICK scan is taking 50 minutes to an hour to run. CNET's review stated a run time of much less (seconds?). My computer is a 2002 Dell 8200, XP SP3, 2G, 512 RAM; the malware settings are all checked EXCEPT Terminate IE during removal. Any idea why it is taking so loooong.

Thank you,

ouch . Ram is the answer I would be willing to bet .

[mbyuser]

this is something thats being a concern for myself.
i thought somthing wasnt right but nothings being found as with search & destroy/webroots antivirus/antispyware.
so i thought somehow it was down to faster/newer versions,however now i read the normal time i am very suspect.

a full scan went from 2hrs to round about 20mins.
the only thing i can think off is i did have a update issiue so instaled one update manually,but thats was a while back.
it didnt occur to me till now that might be why.
i guess i should look at reistalling and getting back if its still so quick.

in the mean time,any other suggestions as to why this is so quick?

[mbyuser]

reinstalled still only taking 20 mins to complete and only 4 mins on a quick scan.
is there a unistallier for malwarebytes? (to remove reg entries)
with malwarebytes being so quick to complte a full scan should i be posting in the malware forum?
