Possible Infection - PUP. Optional FrostwireTB.A

Recommended Posts

Dear Sirs

Undertaken Hyper Scan this morning and nothing detected closely followed by "threat scan" where upon 33 objects were detected all starting with PUP.Optional.FrostwireTB.A


I firstly quarantined these then selected for deletion then restarted my PC


I've undertaken the same scan procedure and once again all 33 objects have been detected.


Running Windows 7 Ultimate with Mcafee Total Protection along with Purchased Malwarebytes Premium.


There has never been anything like this on previous scans and my pc is used mainly for work purposes with occasional careful internet use.


All Malwarebytes software updated on a daily basis.


Can you advise if this is an infection and if so how should I proceed.


I have now downloaded and run the Farbar Recovery Tool and have both logs available if need be 


Many thanks

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 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.

Backup the Registry:
Modifying the Registry can create unforeseen problems, so it always wise to create a backup before doing so.
  • Please download ERUNT from one of the following links: Link1 | Link2 | Link3
  • ERUNT (Emergency Recovery Utility NT) is a free program that allows you to keep a complete backup of your registry and restore it when needed.
  • Double click on erunt-setup.exe to Install ERUNT by following the prompts.
  • NOTE: Do not choose to allow ERUNT to add an Entry to the Startup folder. Click NO.
  • Start ERUNT either by double clicking on the desktop icon or choosing to start the program at the end of the setup process.
  • Choose a location for the backup.
    • Note: the default location is C:\Windows\ERDNT which is acceptable.

    [*]Make sure that at least the first two check boxes are selected. [*]Click on OK [*]Then click on YES to create the folder. [*]Note: if it is necessary to restore the registry, open the backup folder and start ERDNT.exe

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 RogueKiller and save it to your desktop.

You can check here if you're not sure if your computer is 32-bit or 64-bit

  • RogueKiller 32-bit | RogueKiller 64-bit
  • Quit all running programs.
  • For Windows XP, double-click to start.
  • For Vista,Windows 7/8, Right-click on the program and select Run as Administrator to start and when prompted allow it to run.
  • Read and accept the EULA (End User Licene Agreement)

Thanks for your response.


Could I firstly check if this is a known virus or otherwise?


The reason being that I have been having a one to one communication with a lady called Deb who also posted on the forum re the same problem and both of our research has led to it all pointing to Ask.com.


I have quarantined all the PUP's however I have uninstalled the Ask.com toolbar and Ask updater, rebooted then hyper scan and threat scan with "no detections". Deb has not been able to do this as she does not have administrators permissions whilst her employer is away.


I have scanned again since and no further detections.


I didn't want to delete the PUPs as they appear to be registry files and didn't want to do any damage to my PC. 


I have taken screen shot of the files for your attention and pasted into a word document if thats ok? although this shows a few of them ticked for deletion I unchecked them and left as they were.


I run Windows 7 64bit and have MB premium. I update several times daily so was surprised to spot this alert.


I'm not too technical minded so if this appears to be some form of false alarm caused by Ask.com I would rather leave it at that without all the other.


If that is the case what should I do with the quarantined files?


If I have to go with your list I may have to prepare myself!!


Appreciate your help either way

Frostwire is peer2peer software that is very likely going to alert for PUP (Possibly Unwanted Program) as they bundle junk with it.


If using Avira it unfortunately does use the ASK Toolbar and some features will not work if you disable it. That said I'd still either disable it myself or change antivirus as I'm not personally willing to put up with any toolbars being foisted onto me.


Please read the following whic explains why the ASK toolbar is not good.
IAC / Ask.com toolbars

Beyond that without other logs there is no way to tell for sure what's going on. It is almost certain you do not have any virus as that is typically misinformation. Most infections are malware not virus.


If you wish to proceed then yes please run the scans and post the logs.


Thank you
