Hello shaharpit809 and welcome to Malwarebytes,

Can you do the following and check for untrusted certificates:

  • Select Windows key and R key together,,
  • In the Run dialog box type MMC, and then click OK.
  • The Microsoft Management Console (MMC) appears.
  • In the MMC, on the Console menu, click File then Add/Remove Snap-in....
  • In the Add or Remove Snap-in dialog box, click Certificates, and then click Add.
  • In the Certificates snap-in dialog box, click My User Account, and then click Finish.
  • click OK on Add or Remove Snap ins.
  • Expand the Certificates Current User node by double click
  • Expand UnTrusted Certification by double click
  • Double Click Certificates Trust List.
  • The details pane appears, showing all of the root CA certificates that are currently untrusted.

If there are untrusted Certificates listed for Malwarebytes or any other Security Programs delete them....


Let me know the outcome...

Thank you,

Kevin...

Followed all the steps you mentioned and then tried installing it again. Still faced the same error.
Though whenever I try to run that .exe file, I get the message "This app has been blocked for your protection" so I try giving it administrator rights and then run it. It runs but then gives out the same error.

Thanks for the update, was there any untrusted certificates... ? Run the following and post the two produced logs...

Download Farbar Recovery Scan Tool and save it to your desktop.

Alternative download option: http://www.techspot.com/downloads/6731-farbar-recovery-scan-tool.html

Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way...

Be aware FRST must be run from an account with Administrator status...
 
  • Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.)
  • Make sure Addition.txt is checkmarked under "Optional scans"
  • Press Scan button to run the tool....
  • It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
  • The tool will also make a log named (Addition.txt) Please attach that log to your reply.

Thank you,

Kevin...

Was there any untrusted certificates... ? Yes. There were 2 malwarebytes certificates.

And I had tried using this tool before, as suggested in the above link, I clicked on the fix button and followed the steps but still it didn't work. So this time I clicked on the scan button as suggested by you.

Here are the two files you asked for 

Addition.txt

FRST.txt

Did you remove the two untrusted certificates..? Continue with the following:

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into. "Do not open that file"
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Open FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

Next,

Try Malwarebytes install again.....

Thanks,

Kevin...

Yes you had rogue versions of Chrome and Firefox running on your system... As Malwarebytes will still not run try the following:

Install Malwarebytes via Chamelon...


Download the Chameleon zip file from https://downloads.malwarebytes.org/file/chameleon and extract it to a new folder on your desktop.

Make certain that your PC is connected to the internet and then open the new folder.

Inside the folder expand each sub folder until you have windows folder open with list of entries of renamed Malwarebytes executable files....


user posted image


Double click on each in turn until one will work...

If successful follow the prompts to install and update.

When the update completes amend these settings :-
 
  • Select Settings tab > Detection and Protection sub tab, Detection Options, tick the box "Scan for rootkits".
  • Under Non-Malware Protection sub tab Change PUP and PUM entries to Treat detections as Malware
  • Click on the Scan tab,
  • When complete post the log..



and run a threat scan......

Post that log...

Thank you,

Kevin

After following your instructions, the first file ie. firefox worked completely fine. But even after updating the application, the application still has a 2.2.1.1043 version and was not upgraded to a 3+ version. Hopefully there won't be any issues. Anyway, it worked and I was able to delete the malwares in my system.

Thank you, Kevin

Downloaded the cleaner from the link you provided, after running it, I was asked to reboot and after rebooting a prompt was generated which asked to install 3x version of malwarebytes, so when it was downloaded I tried running it but again it generated the same error ie. Could not call proc. But unlike the prior error no (47:120) this time this time it generated (49:120) if it matters in anyway. Since the above method didn't work, I tried downloading the software from the site you provided but still it didn't work. Can you please tell me what the issue actually is? Since the latest version doesn't seem to work on my system.

The issue you have is normally associated to an untrusted certificate being created that will stop Malwarebytes from either installing, or running if already installed.

When you checked for untrusted certificates were there any others apart from the two you mentioned earlier?

All of those entries are designed to stop the named program from either running or installing, I no longer see Malwarebytes in the list so there is maybe a group policy or similar still doing a similar job..

Delete all of those entries you have listed...

In any case don't remove on your own anything that Hitman Pro detects! This scanner is really good for checking, it has however been known for deleting files instead of curing them, in some cases this may render the machine unbootable.

Please download HitmanPro by SurfRight and save it to your desktop.
Temporary disable your AntiVirus and AntiSpyware protection - instructions here.

  • Click on the Next button. You must agree with the terms of EULA (if asked).
  • Check the box beside No, I only want to perform a one-time scan to check this computer.
  • Click on the Next button.
  • The program will start to scan the computer. It would only take several minutes.
  • When the scan is done click on drop-down menu of the found entries (if any) and choose - Apply to all => Ignore.
  • If there isn't a dropdown menu when the scan is done then please don't delete anything and close HitmanPro!Navigate to C:\ProgramData\HitmanPro\Logs, open the report and include it it your next reply.
  • Click on the Next button.
  • Click on the Save Log button.
  • Save that file to your desktop.
