Hi and welcome.
Not an unwise decision to make. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. Wiping your drive, reformatting, and performing a clean install of the OS or doing a factory restore removes everything and is the safest action but I cannot make that decision for you.
Reformatting a hard disk deletes all data. If you decide to reformat, you can back up all your important documents, data files and photos. The safest practice is not to backup any autorun.ini or .exe files because they may be infected. Some types of malware may disguise itself by adding and hiding its extension to the existing extension of files so be sure you take a close look at the full name. After reformatting, as a precaution, make sure you scan these files with your anti-virus prior to copying them back to your hard drive.
2 guidelines/rules when backing up
1) Backup all your important data files, pictures, music, work etc... and save it onto an external hard-drive. These files usually include .doc, .txt, .mp3, .jpg etc...
2) Do not backup any executables files or any window files. These include .exe/.scr/.htm/.html/.xml/.zip/.rar files as they may contain traces of malware. Also, .html or .htm files that are webpages should also be avoided.

Since we don't know exactly which infections we're dealing with here, we should take some precautions before we attempt to move files from the infected machine. Run the following on your clean computer, and make sure you insert your flash drives at the prompt.Download and Run FlashDisinfector
Please download Flash_Disinfector.exe
by sUBs and save it to your desktop.
Note: As part of its routine, Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive that was plugged in when you ran it. Do not delete this folder...it will help protect your drives from future infection by keeping the autorun file from being installed on the root drive and running other malicious files.Reinstall Windows Vista
- Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
- The utility may ask you to insert your flash drive and/or other removable drives. Please do so and allow the utility to clean up those drives as well.
- Hold down the Shift key when inserting the drive until Windows detects it to keep autorun.inf from executing if it is present.
- Wait until it has finished scanning and then exit the program.
- Reboot your computer when done.
You have a rootkit. If you want to try to clean it and it will be several days then...
As there are some new variants of rootkits in the wild right now that will require custom scripts to remove the infection, the process must be completed by HJT team member.Failure to follow the proper removal process can and will cause serious damage to a machine. Recovery of the machine may be difficult, if not impossible.
