Hi all,
 
I´m new here and is sitting in front of a friends laptop with windows 7.
 
Som Malware has completely taking over the computer. It is eating memory like crazy. Security websites are blocked. The computer does NOT have antivirus, when trying to download, the site is blocked. Updates for Windows has never been taken care of, Etc, etc, etc.
 
Have had one go with Malwarebytes, and it removed a lot of stuff, mainly cookies. I have used Revo Uninstaller to remove all nonimportant programs.
 
Any sugestion how I can continue, or should I throw the lap in the pool??
 
Any help is really apreaceated.
 
Best regards,
Monica, a Swede living in Madrid.

Hello, and Welcome to BC

 

Download Kaspersky Rescue Disk (linux based) on another computer. It is an iso file which can be burned on a Windows 7 computer by right clicking and selecting Burn Disk Image. Connect the computer via an ethernet cable as this will allow the definitions to be updated. Boot the disk and run the Antivirus. Read the User Guide.

 

Edit: Here is a good video on Kaspersky.

 

After cleaning boot back into windows and try to run HitmanPro. After HitmanPro run Malwarebytes Chameleon. Chameleon allows Malwarebytes to be installed and run if an infection prevents the download. You may need to download it on another computer. After Malwarebytes run TDSS killer. Check all options.

 

Run the following in order

 

TFC

Adwcleaner

Junkware Removal Tool

 

Install Bitdefender Free or Panda Free for an AV. Bitdefender Free requires an account setup.

 

The safest thing to do would be to perform a factory reset after backing up all personal data. If the computer is an OEM it should have a factory recovery partition that is started by pressing a key at boot. What is the make and model of the computer?

In addition to what John said, you can have another option of following the Preparation Guide and post in the Malware Removal Logs area. A malware removal specialist will guide you through manual cleaning of the machine.
