Hi, 

 

For the last 2 weeks every time I scan my computer with Malwarebytes it shows that there is 1 infected file, in the: C:\Users\Username\AppData\Local\Google\Chrome\User Data\Default\File System\000\t\00\00000000. It says that it is a PUP.Optional.Installrex and I get rid of it everytime but it keeps returning. I have no idea what causes this so I hope someone can help ;)

 

This is what the log says btw (in Dutch partly sorry for that) :

Hello, Welcome to BleepingComputer.
I'm nasdaq and will be helping you.

If you can please print this topic it will make it easier for you to follow the instructions and complete all of the necessary steps in the order listed.

I see you are running an outdated version of Malwarebytes Anti-Malware.
To update, open the program, click the Update tab, and click the 'Click here to find out more and check it out!' link - see screen-shot.

Run the application and clean everything that is found.

Double-click mbam-setup-2.X.X.XXXX.exe to install the application (X's are the current version number).
  • Make sure a checkmark is placed next to Launch Malwarebytes' Anti-Malware, then click Finish.
  • Once MBAM opens, when it says Your databases are out of date, click the Fix Now button.
  • Click the Settings tab at the top, and then in the left column, select Detections and Protections, and if not already checked place a checkmark in the selection box for Scan for rootkits.
  • Click the Scan tab at the top of the program window, select Threat Scan and click the Scan Now button.
  • If you receive a message that updates are available, click the Update Now button (the update will be downloaded, installed, and the scan will start).
  • The scan may take some time to finish,so please be patient.
  • If potential threats are detected, ensure that Quarantine is selected as the Action for all the listed items, and click the Apply Actions button.
  • While still on the Scan tab, click the link for View detailed log, and in the window that opens click the Export button, select Text file (*.txt), and save the log to your Desktop.
  • The log is automatically saved by MBAM and can also be viewed by clicking the History tab and then selecting Application Logs.
Note:
If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts.
Click OK to either and let MBAM proceed with the disinfection process.
If asked to restart the computer, please do so immediately.

Please download AdwCleaner by Xplode onto your Desktop.
  • Close all open programs and internet browsers.
  • Double click on AdwCleaner.exe to run the tool.
  • Click the Scan button and wait for the process to complete.
  • Click the Report button and the report will open in Notepad.
IMPORTANT
  • If you click the Clean button all items listed in the report will be removed.
If you find some false positive items or programs that you wish to keep, Close the AdwCleaner windows.
  • Close all open programs and internet browsers.
  • Double click on AdwCleaner.exe to run the tool.
  • Click the Scan button and wait for the process to complete.
  • Check off the element(s) you wish to keep.

Download the correct version of this tool for your operating system.
Farbar Recovery Scan Tool (64 bit)
Farbar Recovery Scan Tool (32 bit)
and save it to a folder on your computer's Desktop.
Double-click to run it. When the tool opens click Yes to disclaimer.
Press Scan button.
It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.

Please paste the logs in your next reply DO NOT ATTACH THEM unless specified.

Let me know what problem persists.
