Bad bad bad virus on sisters friends laptop

You dont need to get into windows, you can download AVIRA wich is a free virus checker that runs from a boot cd in a mini linux shell. Use that to quarantine the files and then get into windows and use malwarebytes to clean up!

Its called the rescue system on the list......Ive used it many times with great results!

which one is the iso?

go to this link:

then look down the list for rescue system, there will be two. One has a picture of a cd on the far right next to the file size of 55,094. Thats an ISO.

If youve already booted into the virus checker, click the little british flag on the bottom left corner. Im guessing its currently running in german.

If you go into the settings menu you can tell it to quarantine anything that it cant delete. After that try booting into windows. If you can get this far I recommend malwarebytes to remove the rest.

If that doesnt work I would run AVIRA again and make sure you let it update its definitions.

so you ran the scan and quarantined or deleted the bad files?

EDIT: If your freezing during the boot virus scanner, this would suggest maybe there is a hardware issue. At this point you can do a few other things like boot into a linux live cd and manually delete the bad files from there, or run a different boot virus check. It maybe just easier for you to reformat and reinstall the OS if youre not worried about loosing any personal files.

If you do have files you need to get off the pc before the reformat you can also do this in linux from a live cd.

Good Luck.
