Formatting Laptop with windows 7

Hello, My girlfriends laptop has windows 7 home premium with the serial number located on the underside of the computer. Somehow she has messed up her computer with virus' so bad that you cant do anything. I just wanna do a clean install. I dont need to backup or save anything. This laptop came with no discs. How do I do this. I can use my computer to download or make any discs necessary.

MS Windows 7 Ultimate SP1 64-bit

Before you throw in the towel, put Microsoft Standaalone System Sweeper on to a USB and boot up her computer to the USB.

Just be sure to down load the 32 bit version if that's what she has installed and to download the 64 bit version if that's what she has installed.


System Sweeper,, allows you to start an infected PC and perform an offline scan to identify and remove viruses, rootkits and other advanced malware. System Sweeper is a free standalone, bootable malware and virus remover from Microsoft.

Safety Scanner, Microsoft Safety Scanner - Antivirus | Remove Spyware, Malware, Viruses Free, is free, downloadable, provides on-demand scanning and helps remove viruses, spyware, and other malicious software. It works with your existing antivirus software.

If the target computer has a working internet connection, then you may prefer to use the Safety Scanner.

Download System Sweeper (about 576 kB):

Insert 256 MB or larger USB stick into a usb port.

Run the downloaded program--mssstool64.exe or mssstool32.exe

Choose the option to install to USB.
Caution: The install program will format the usb stick.

The install program will download about 200 mB more.

After the install is finished, leave the stick in the usb slot.

Run the program you downloaded once again.

This 2nd run, and any subsequent runs, will download the very latest anti-virus definitions (about 60 mB).

To keep System Sweeper up-to-date, simply reinsert the usb stick and run the installation program, mssstool64.exe or mssstool32.exe, again.

The initial, full scan by System Sweeper can easily take several hours, but subsequent quick scans will be shorter.

Remember, your computer is being very thoroughly checked for all types of malware.

The results of System Sweeper will be in:
\Windows\Standalone System Sweeper\Support as one or more files with a LOG extension which can be viewed with Notepad.

We also have a fine tutorial on this:

Hello kevilay, to clean install you'll need to locate (borrow/download) a disk. You'll have to be careful to install home premium only (can be 32 bit or 64 bit, doesnt matter).

You can still make recovery disks but if its an issue you can order a set from whichever OEM made that computer for a nominal price.
