Hello everyone,

This seems like an unusual problem.

I have a Lenovo 3000 C200 laptop, XP Pro, 1.73 GHz, 2.49 GB of RAM, the computer seems to run fine.

Last evening I ran Avira after an update and it stopped responding after 14 minutes. I restarted the computer and tried it again and it stopped after 14 minutes of scanning.

I uninstalled the program restarted and reloaded it and updated it and ran it again, it stopped at 14 minutes.

Next I updated and ran Malwarebytes and it stopped working after a few minutes of scanning.

I then started the computer in safe mode and ran both programs and they both completed the scans with no problems, reporting no infections.

Then I tried each program in normal mode and they both locked up again.

I then ran SuperAntiSpyware and it scan OK and reported no infections.

How can I figure out what is causing this.

Thanks for the help.

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, uninstall unnecessary programs, clean out the temporary files or use ATF Cleaner first, close all open programs and do not use the computer during the scan.

Note: It is not unusal for an anti-virus or anti-malware scanner to be suspicious of some compressed, archived, .cab and packed files because they have difficulty reading what is inside them. These kind of files often trigger alerts by security software using heuristic detection because they are resistant to scanning (difficult to read). This resistance may also result in some scanners to stall (hang) on these particular types of files.

Thanks for the tips quietman7, but I am not saying it is slow, but that it locks up and does not respond. I can't even close it, I have to use end program.

I use CCleaner and keep the computer defragged and clean.

I have no extra drives or programs running when I did the scans.
.

I just tried MAB again on quick scan and it completed the scan OK, then I tried it on full scan and it locked up. The MalwareBytes program, not the whole computer.

As I said in my note, MBAM may be getting hung on a specific file for the reasons I indicated. 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 thought it might be a specific file also because Mbam stopped on a file called MSN core in the program files on C drive, I looked at that folder and it was empty, so I deleted it and tried the scan again and it locked up again.

I also tried running it on just the D drive where I have My Documents and it locked up there, also.

It seems as though it is just Avira and Mbam are the only ones that won't finish a scan, the only other scan program I have installed is SuperAntiSpyware and it zips right through and reports no infection.

I was thinking maybe I should try scanning with another program, does anyone have any suggestions?

Why not report this issue in the Malwarebytes Anti-Malware Support Forum? You can do the same at the Avira Support Forum.

This is really strange, I have another computer that is also a Lenovo 3000 C 200 with the same programs and specs as the other one that is having the problem and this one scans fine.

Another thing I noticed is that the Avira always stops at 14.6 percent of completion

The Malewarebytes will do the D drive now, but stops in the C drive usually around m in the Program files.

In safe mode they both work fine.

I just registered at the Avira forum this afternoon, I will also check out the Malwarebytes site.

Thanks again for the help, if I get this resolved, I will post.

Hello Quietmam7,

I figured it out with your help from a 2007 post of yours that you are probably trying to forget.

http://www.bleepingcomputer.com/forums/t/105569/hang-up-when-they-encounter-csystem-volume-informationtrackinglog/

Anyway, I noticed it kept hanging on Volume Tracking log and I Googled it came up with lots of people having this problem in 2007 and I put the exception in Avira and it scanned OK.

Now I have to figure out how to put the exceptions in MalwareBytes.

Thanks

Yes, the tracking log in SVI can be one of the culprits.

Again you may want to report this issue with it in the Malwarebytes Anti-Malware Support Forum. If you do, let us know what they say about it.
