While you are in need of help, take some time to read what information you supplied. No make/model or error messages. No indication if your backup is good to be used so we can start over.
In closing, your plight is typical of spyware and malware infestations and what happens on a Windows Update. This frap is causing many people issues so don't feel you were singled out.
