BiuiyNsave/BuyNSave Malware Problem


Recommended Posts

Hi,

 

Caught this thing a few days ago. It keeps adding the extension mentioned in the title, and opening a tab with MyStartSearch.com, every time I start up Chrome.

 

Initially ran an AVG scan, then have scanned a few times with Malwarebytes Anti-Malware. It cleaned up a few things, and Malwarebytes doesn't show any more threats, but this thing keeps coming back.

 

I've seen this thing being reported before on here, so thought this'd be the best place to come to resolve this issue.

 

I've followed the first steps of the pinned topic, and have attached my FRST and Addition logs.

Hello,
    
 
They call me TwinHeadedEagle around here, and I'll be working with you.
 
     
    
Before we start please read and note the following:

  • Limit your internet access to posting here, some infections just wait to steal typed-in passwords.
  • Please be patient. I know it is frustrating when your PC isn't working properly, but malware removal takes time.
  • Don't run any scripts or tools on your own, unsupervised usage may cause more harm than good.
  • Do not paste the logs in your posts, attachments make my work easier. There is a More reply options button, that gives you Upload Files option below which you can use to attach your reports. Always attach reports from all tools.
  • Always execute my instructions in given order. If for some reason you cannot completely follow one instruction, inform me about that.
  • Stay with me to the end, the absence of symptoms doesn't mean that your machine is fully operational.
  • Note that we may live in totally different time zones, what may cause some delays between answers.
  • Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay someone to repair it.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.

:excl: I can't foresee everything, so if anything unexpected happens, please stop and inform me!
:excl: There are no silly questions. Never be afraid to ask if in doubt!

Chrome is altered by malware, you will need to reinstall it completely.
 
 
FRST.gif Fix with Farbar Recovery Scan Tool
 

icon_exclaim.gif This fix was created for this user for use on that particular machine. icon_exclaim.gif
icon_exclaim.gif Running it on another one may cause damage and render the system unstable. icon_exclaim.gif

 
Download attached fixlist.txt file and save it to the Desktop:
 
Both files, FRST and fixlist.txt have to be in the same location or the fix will not work!

  • Right-click on FRST.gif icon and select RunAsAdmin.jpg Run as Administrator to start the tool.
    (XP users click run after receipt of Windows Security Warning - Open File).
  • Press the Fix button just once and wait.
  • If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
  • When finished FRST will generate a log on the Desktop, called Fixlog.txt.

Please post it to your reply.

The Importance of Software Updating:

 

 
In order to stay protected it is very important that you regularly update all of your software. Cybercriminals depend on the apathy of users around software updates to keep their malicious endeavor running.
 
Operating systems, such as Windows, and applications, such as Adobe Reader or JAVA, are used by tens of millions of computers and devices around the world, making them a huge target for cybercriminals. Downloading updates and installing them can sometimes be tedious, but the advantages you get from the updates are certainly worth it.

Recommended additional software:

 
 
icon_arrow.gifTFC - to clean unneeded temporary files.
icon_arrow.gifMalwarebytes' Anti-Malware - to scan your system from time to time in search for malware.
icon_arrow.gifMalwarebytes' Anti-Exploit - to prevent plenty of mostly exploited vulnerabilities.
icon_arrow.gifMcShield - to prevent infections spread by removable media.
icon_arrow.gifUnchecky - to prevent from installing additional foistware, implemented in legitimate installations.
icon_arrow.gifAdblock - to surf the web without annoying ads! 
 
 

Post-cleanup procedures:

 

 
Download DelFix by Xplode and save it to your desktop.

  • Run the tool by right click on the 51a5ce45263de-delfix.png icon and Run as administrator option.
  • Make sure that these ones are checked:
    • Remove disinfection tools
    • Purge system restore
    • Reset system settings
  • Push Run.
  • The program will run for a few seconds and display a notepad report. You do not need to attach it.

The tool will also record healthy state of registry and make a backup using ERUNT program in %windir%\ERUNT\DelFix
Tool deletes old system restore points and create a fresh system restore point after cleaning.
