I attempted to run a full scan on my C drive using Malwarebytes but gave up after 15 hours. Yes, that's right I said 15 hours. I started the scan around 1:20pm and finally got fed up and turned it off around 6:20am.

I know that different Anti-virus tools use different methods and that a full scan isn't as fast as the fast scan but 15 hours is ridiculous!!!:thumbsup:

I've run a full scan using PCtools including all three of my drives and that only took 9 1/2 hours so I don't understand why Malwarebytes took that long and still wasn't finished when I finally got fed up and turned it off. Does the amount of memory and the CPU effect the scan???

That as well as the amount of data on the drives effects scan time.

MBAM look`s extremely deep when set to do a full scan.

ThunderZ:

I didn't have any other software running when I run a scan, that's all I do because I know that takes precedence over anything else.

As for my computer setup I have a 2.4 Intel Pentium 3 CPU with 1 GB of memory. I wish I had Duo Core or that Extreme Core by Intel and at least 2GB of memory but I don't so I have to work with what I have. Okay so the MBAM scan will take 20 - 24 hours??? Okay, maybe I'll give it another whirl. I know there's something on this computer because my pctools blocked something trying to access my System 32 file but MBAM didn't find it when I did a quick scan earlier. :thumbsup:

If PCtools blocked something and your PC is not acting strangely then you are most likely clean.

If you are concerned about infection then it would be located on you Windows (C:) drive. That is really all I would be concerned with scanning.

I have a lot less ram than you do and have never had a Malwarebytes scan take anywhere near that long. A quick scan takes less than ten minutes and it seem like the full scan takess about an hour on my system. My hard drive is not all that big but even on a very large hard drive I doubt it should take more than a couple of hours

If you use real-time scan tools that monitor registry changes, such as Spybot's Teatimer function, tihs can happen

The speed of 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 for suspicious behavior or a combination of both.
  • Options to scan for spyware, adware, riskware and potentially unwanted or unsafe 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.
  • Type of operating system installed on the computer.
  • A computer's hard drive size.
  • Disk used capacity (number of files to include temporary files) that have to be scanned.
  • Types of files (.exe, .dll, .tmp, .sys, .cab, archived, compressed, packed, email, etc) that are scanned.
  • Whether external drives are included in the scan.
  • Competition for and utilization of system resources by the scanner.
  • Other running processes and programs in the background.
  • Interference from malware.
  • Interference from the user.
To speed up your scans, clean out the temporary files or use ATF Cleaner first, close all open programs, do not use the computer during the scan and then make sure you only do a Quick Scan. MBAM is designed to remove malware as effectively with a Quick Scan as it will with a Full Scan which takes much longer to complete. Both do full heuristics, memory, load points and multiple other malware checks. The Quick Scan looks at the most prevalent places for active malware so scanning every single file on the drive isn't always necessary. The Full Scan only has the ability to catch more traces in rare circumstances.

I agree with quietman7, in my experience a full malwarebytes scan has taken MAX 2 mmaaaayyybbbee 2 1/2 hours but this is the first time I read 15 hours!!

I would suggest taking the hard drive out and using a different PC to scan that hard drive with MalwareBytes or maybe even Avast Anti-Virus

Good Luck!
