New MalwareBytes scans far quicker, but is it as thorough?

[FrackyMacky]

I upgraded to MalwareBytes (Free) yesterday.  It' version 2.0.2.1012, snazzy new look.  I think (but can't verify anymore) that I could choose a full scan that would take forever.  Now there doesn't seem to be anything to distinguish a full scan from whatever a non-full scan is.  A scan simply takes mere minutes.  What has changed?  Is this scan as thorough?

Thanks, that does indeed inform.  However, I chose to scan the entire C drive, but it still only takes a fraction of the time it use to.  Has something fundamentally changed with this new version?

Hello FrackyMacky:

So as to give us additional clarity, please attach the .txt (not the .xml version) version of your Scan Log for your entire C:\ drive and the Protection log that coincides to the times that covered your Custom Scan of the C:\ drive, in a reply to this thread.

Thank you.

I am examining http://www.malwarebytes.org/support/guides/mbam

 

I have Applications Logs but not Daily logs.  For Applications Logs, there does not seem to be the ability to export to text file.

 

Is there a decent way to upload these?

Please open Malwarebytes Anti-Malware and from the Dashboard please Check for Updates by clicking the Update Now... link
Open up Malwarebytes > Settings > Detection and Protection > Enable Scan for rootkits, Under Non Malware Protection set both PUP and PUM to Treat detections as malware.
Click on the SCAN button and run a Threat Scan with Malwarebytes Anti-Malware by clicking the Scan Now>> button. Remove any threats found
Once completed please click on the History > Application Logs and find your scan log and open it and then click on the "copy to clipboard" button and post back the results on your next reply.

Please read the following and post back the 3 requested logs.

Hello,

 

Thanks for the instructions.  The files are attached.  I ran mbam-check and FRST64 before turning on detection of rootkits.  Please note that there is one detail which I did not adhere to: I left PUP at the default of warning the user.  I wanted to first ask what the risk was of doing damage.

You are getting some errors that could just be software conflict or corruption but probably best to check it out and make sure there are no infections.

I would suggest following the advice from the topic here Available Assistance for Possibly Infected Computers and having one of the Experts assist you with looking into your issue.

Thanks

Ron, I appreciate the advice to date.  Before I pursued this any further, I was wondering if you can comment on the question of whether the new MalwareBytes can be expected to take signficantly less time to scan compared to a full scan of the C drive for the old MalwareBytes?  I'm intending this question to be general rather than what could be wrong with my specific computer.  I typically scan with MalwareBytes, Spybot S&D, and Microsoft Security Essentials, so I'm somewhat confident that I don't have particularly nasty stuff on my computer.  I'm more interested on how to calibrate my expectations for the new MalwareBytes.

[AdvancedSetup]

I don't think there is anything nasty there either. Just some minor stuff but we don't do full detection and removal except in that other forum.

 

As for speed of a scan... that is not exactly black and white. In general the scanner is faster however it now supports archive scanning, rootkit scanning, improved heuristic scanning which themselves can add to the time taken to do a full scan. The Threat Scan and Hyper Scan may typically run close or faster than the previous version but if you do a Custom Scan and enable everything I would expect it to take a least a little longer to scan the exact same computer than the previous version. The new scanner is certainly more capable of detection and removal of items that the 1.75 version could not address.

 

So bottom line, yes Threat and Hyper are probably faster. Custom is probably not (when all options are selected) - though I would not say drastically faster.

[FrackyMacky]

Hmmm, interesting.  I remember MalwareBytes taking a long time for scan of the entire system, but I can't verify that now.

 

Thanks for the info, Ron.

Okay, you're welcome. If there is nothing else then we'll probably close this topic soon.

 

Take care
