Hello

 

This is my first post here so forgive any mistakes or missplacements.

 

My nephew was using my laptop as he loves to game (so do I), when I heard Avast antivirus saying threat detected which made me come and check what was going on. I realised There where tons of programs installed due to a file he installed from the web, lots of unwanted preocesses running like XMrig CPU miner and constantly opening system restore window.

Due to the amount of things/issues I found I decided to do a factory reset (which I will be starting once I have posted this in hopes of geting an answer when I´m back).

 

What I would like to ask is:

 

What I should be doing after the reset to be sure I have no rootkits or any other nasties?

 

 

My system info is the following:

Processor         

Intel® Core™ i5-5200U CPU @ 2.20GHz

Video Card

Intel® HD Graphics 5500

Video Card

NVIDIA GeForce 920M

2GB dedicated

RAM

6.0 GB

Operating System

Microsoft Windows 10 (build 16299), 64-bit

 

If you require any other information please just ask (I will be using my phone in the meanwhile).

Thank you in advance

If you do a Reset (Keep Files), it will completely reinstall the OS and retain your files. Any programs that were not installed when the computer was in the box will be removed. This allows you to get rid of anything that you may have picked up, but retain the files you have created. As long as you don't reinstall the malware that your nephew put on there, you should be fine.

Thanks for the quick reply.
Unfortunately it gave an error during reset and went that to where it was:(

Any ideas on what I should do?

You can use the programs below to clean, remove malware and remove adware. That is if you can download, install and run them.

If that is not possible...some malware is blocking their install...then follow the last set of directions for starting a new topic in the malware

removal forum.

 

Use CCleaner to remove Temporary files, program caches, cookies, logs, etc. Use the Default settings. No need to use the

Registry Cleaning Tool...risky. Pay close attention while installing and UNcheck offers of Google Chrome and Avast.

After install, open CCleaner and run by clicking on the Run Cleaner button in the bottom right corner.

CCleaner - PC Optimization and Cleaning - Free Download

 

Malwarebytes - Clean Mode

  • Download and install the free version of Malwarebytes
    Note: If you have Malwarebytes already installed, you don't need to install it again. Simply start from the next bullet point
  • Once Malwarebytes is installed, launch it and let it update its database. You might have to click on the little arrow by Scan Status in the middle right pane for it to do so
  • Once the database update is complete, click on the Scan tab, then select the Threat Scan button and click on Start Scan
  • Let the scan run, the time required to complete the scan depends of your system and computer specs
  • Once the scan is complete, make sure that the first checkbox at the top is checked (which will automatically check every detected item), then click on the Quarantine Selected button
    • If it asks you to restart your computer to complete the removal, do so
  • Click on Export Summary after the deletion (in the bottom-left corner) and select Copy to Clipboard. Paste the content in your next reply

If you are unable to run a scan using MBAM:

Follow the instructions in the thread below. Make sure to download the MBAR linked in it. Let me know if you're not able to launch it and run a scan.

Download AdwCleaner by Xplode onto your desktop. (compatible with Windows 7, 8 and 10)

  • Close all open programs and internet browsers.
  • Double click on adwcleaner.exe to run the tool.
  • Click on Scan button.
  • When the scan has finished click on Clean button.
  • Your computer will be rebooted automatically. A text file will open after the restart.
  • Please post the contents of that logfile with your next reply.
  • You can find the logfile at C:\AdwCleaner[S1].txt as well.

 

Download and run the FREE online scanner from Free Virus Scan | Online Virus Scan from ESET | ESET

  • Place a checkmark in YES, I accept the Terms of Use, then click Start. Wait for ESET Online Scanner to load its components.
  • Select Enable detection of potentially unwanted applications.
  • Click Advanced Settings, then place a checkmark in the following:
    • Remove found threats
    • Scan archives
    • Scan for potentially unsafe applications
    • Enable Anti-Stealth technology
  • Click Start to begin scanning.
  • ESET Online Scanner will start downloading signatures and scan. Please be patient, as this scan can take quite some time.
  • When the scan is done, click List threats (only available if ESET Online Scanner found something).
  • Click Export, then save the file to your desktop.
  • Click Back, then Finish to exit ESET Online Scanner.

Please follow the instructions in the Malware Removal and Log Section Preparation Guide starting at Step 6.

  • If you cannot complete a step, then skip it and continue with the next.
  • In Step 6 there are instructions for downloading and running FRST which will create two logs.

When you have done that, post your logs in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team.

Start a new topic, give it a relevant title and post your log(s) along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. If you cannot produce any of the required logs...start the new topic anyway. Explain that you followed the Prep. Guide, were unable to create the logs, and describe what happened when you tried to create them. A member of the Malware Removal Team will walk you through, step by step, on how to clean your computer.

After doing this, please reply back in this thread with a link to the new topic so we can close this one.

 

DO NOT bump your new topic. Wait for a response from one of the Team Members.

Sry for late reply.

Since I just installed windows 3 weeks ago I ended up doing a full windows install which surely solved the issue.
I apreciate the help though and will save it for any future situation when a reinstall/reset would be very troublesome.

Regards

Thanks for informing us of the steps you have taken.

 

Here is a link to a site that hosts many popular programs that won't be bundled with unwanted junk such as adware...PUPs.
