I understand and that's the decision I would have made if this were my computer. Starting over by wiping your drive, reformatting, and performing a clean install of the OS removes everything and ensures no remnants of malicious files are left behind.
If you're not sure how to reformat or need help with reformatting, please review:

Don't forget you will have to go to Microsoft Update
and apply all Windows security patches after reformatting.Note: If you're using an IBM, Sony, HP, Compaq, Toshiba, Gateway or Dell machine, you may not have an original XP CD Disk. By policy Microsoft no longer allows OEM manufactures to include the original Windows XP CD-ROM on computers sold with Windows preinstalled. Instead, most computers manufactured and sold by OEM vendors come with a vendor-specific Recovery Disk or Recovery Partition for performing a clean "factory restore" that will reformat your hard drive, remove all data and restore the computer to the state it was in when you first purchased it. Also be sure to read Technology Advisory Recovery Media. If the recovery partition has become infected, you will need to contact the manufacturer, explain what happened and ask them to send full recovery disks to use instead.
.Reformatting a hard disk deletes all data
. If you are reformatting or doing a factory restore due to malware infection, you can back up all your important documents, personal data files, photos to a CD or DVD drive, not a flash drive or external hard drive as they may become compromised in the process. The safest practice is not to backup
any executable files (*.exe), screensavers (*.scr), autorun (.ini) or script files (.php, .asp, .htm, .html, .xml ) files because they may be infected by malware. Avoid backing up compressed files (.zip, .cab, .rar) that have executables inside them as some types of malware can penetrate compressed files and infect the .exe files within them. Other types of malware may even disguise itself by hiding a file extension
or adding to the existing extension as shown here
(click Figure 1 to enlarge
) so be sure you look closely at the full file name. If you cannot see the file extension, you may need to reconfigure Windows to show file name extensions
. Then make sure you scan the backed up data with your anti-virus prior to
to copying it back to your hard drive.
If your CD/DVD drive is unusable, another word of caution if you are considering backing up to an external usb hard drive as your only alternative. External drives are more susceptible to infection and can become compromised in the process of backing up data
. I'm not saying you should not try using such devices but I want to make you aware of all your options and associated risks so you can make an informed decision if its worth that risk.
Again, do not back up any files with the following file extensions: exe, .scr, .ini, .htm, .html, .php, .asp, .xml, .zip, .rar, .cab as they may be infected.
