To get to your documents, you can remove the hard drive and connect it to a USB-to-hard-drive adapter, then plug the USB into another computer (that has its own anti-malware programs running) and access your documents and copy them. You can get these adapters from

You might check with a computer repair shop, they will have these adapters and might rent you the device for a small fee.
Get an USB external hard drive, these are made by Seagate, Maxtor, Western Digital, Iomega, Verbatim, and many others, and sold at Best Buy, Office Max, Office Depot, and others.
Use the external hard drive to make fast and easy copies of all of your important documents (it's faster than burning CDs or DVDs).
More importantly, after you get rid of the malware on your computer, make a full backup of the computer, so that in the future if you get clobbered again, you can reload the backup and be running again. Be aware that a full backup can take over 20 minutes to run - and a full restore likewise will take over 20 minutes to run.
To completely get rid of malware, it is usually necessary to reinstall the operating system. The jerks who write the malware are constantly revising it to keep the anti-malware software from shutting the mal-ware down. It's a never ending battle.
But you said you might get a new computer - be sure to make backups, because it is much easier to restore a backup than it is to reinstall the operating system.
