Cannot remove PUP.Optional.CrossRider - HELP PLEASE


Recommended Posts

Hello,

I am having a problem removing malware from my computer. It is causing the web browsing to operate very slowly / not at all. I have run MBAM and it identifies four PUP.Optional.CrossRider files (Two registry keys and two registry values).

I have repeatedly tried quarantining the files and deleting them, but they reappear each time I restart the machine. 

I have also tried using ADW Cleaner, JRT and MBAR to isolate the files, but they are unable to locate them.

Does anyone have any suggestions as to how I can purge these files for good?

Thanks.

STEP 01
RKill is a program that was developed at BleepingComputer.com that attempts to terminate known malware processes so that your normal security software can then run and clean your computer of infections.
When RKill runs, it will kill malware processes and then removes incorrect executable associations and fixes policies
that stop us from using certain tools. When finished it will display a log file that shows the processes that were
terminated while the program was running.

As RKill only terminates a program's running process and does not delete any files, after running it, you should not reboot
your computer as any malware processes that are configured to start automatically will just be started again.
Instead, after running RKill, you should immediately scan your computer using the requested scans I've included.

Please download Rkill by Grinler from one of the links below and save it to your desktop.

Link 1 | Link 2

  • On Windows XP Double-click on the Rkill desktop icon to run the tool.
  • On Windows Vista/Windows 7 or 8, right-click on the Rkill desktop icon and select Run As Administrator
  • A black DOS box will briefly flash and then disappear, this is normal and indicates the tool ran successfully.
  • If not, delete the file, then download and use the one provided in Link 2.
  • If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
  • If the tool does not run from any of the links provided, please let me know.
  • Do not reboot the computer; you will need to run the application again.

 

STEP 02
Please run a Threat Scan with MBAM. If you're unable to run or complete the scan as shown below, please see the following:
MBAM Clean Removal Process 2x
When reinstalling the program, please try the latest version.

Right click and choose "Run as administrator" to 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 rootkit and 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.
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 download the attached fixlist.txt file and save it to the Desktop.

Run FRST or FRST64 and press the Fix button just once and wait.
If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Desktop (Fixlog.txt). Please attach or post it to your next reply.

Hi, I think we're getting there. MBAM scan no longer shows the CrossRider files so they appear to have been purged from the system (yay). 

Chrome still seems to be buggy - will run ok the first time its loaded in a session, but after a few minutes it is very slow and often still fails to load pages. Any suggestions?

Also, part way through the debugging process, MBAM decided it needed to update. Now it sometimes comes up saying that it is unable to load the Rootkit element, and this may be caused by Malware activity. Should I worry about this?

Thanks

Please visit each of the following sites and let's reset all of your browsers back to defaults to prevent unexpected issues.
If you are not using one of the browsers but it is installed then you may want to consider uninstalling it as older versions of some software can pose an increase in the potential for an infection to get in.

Internet Explorer
How to reset Internet Explorer settings

Firefox
Click on Help / Troubleshooting Information then click on the Reset Firefox button.

Chrome

I would like to reset Chrome back to defaults to completely clear out what is going on with Chrome.

You can keep your “Bookmarks” if you want to keep them, but you have to export them first – >> Export Bookmarks << – Everything else should be removed.

Then I need you to go to >> Google Sync << and sign into your account.
Scroll down until you see the reset sync button and click on the button
At the prompt click on Ok.

.
Reset Your Browser Settings
.

  1. In the top-right corner of the browser window, click the “Chrome Menu” icon (Three horizontal lines)
  2. Select Settings.
  3. At the bottom, click Show advanced settings…
  4. Scroll down until you see “Reset settings”, Then click on the button Reset Settings.
  5. In the dialog that appears, click Reset.

.
Close Chrome and restart it and check it out for me please

Assuming the computer is not at fault let's take a look at resetting your router and see if that helps or not.

Please review the following website and read it before continuing and then do a Hard Reset back to Factory Defaults for your router.
This information is only for resetting the router DO NOT erase, install, or update the firmware, just reset your router to factory defaults.

Reset And Reboot

Hard reset or 30/30/30

Hi, resetc router as described, but problem still occurred. 

However I think I've now cracked it! The network connection was OK for Skype and Dropbox, but not for any of the Web browsers. I changed the DNS settings of the network connection to OpenDNS using the guide here http://www.howtogeek.com/164981/how-to-switch-to-opendns-or-google-dns-to-speed-up-web-browsing/

That appears to have resolved the slow browsing issue on all of the browsers. Had 24hrs operation and all good so far!

Thank you for all your help!!!  

Is there any outstanding bits we need to wrap up?
