Back-up any personal data (none of which should be considered 100% trustworthy at this point) then format the HDD & do a clean install of Windows.  Please note that a Repair Install (AKA in-place upgrade) will NOT fix this!
HOW TO do a clean install of Vista: See the "If you want to reinstall Windows Vista by performing a clean installation..." section of

http://windows.microsoft.com/en-us/windows-vista/Installing-and-reinstalling-Windows-Vista
Note: The manufacturer was required to provide a way to reinstall Windows.
If a set of disks didn't come with the computer, there will be a hidden Recovery partition (not to be confused with System Restore) you would use to do the clean install.
Contact the manufacturer for guidance.
After the clean install, you'll have the equivalent of a "new computer" so take care of everything on the following page before otherwise connecting the machine to the internet or a local network  (i.e., other computers) and before using a flash drive or
SDCard that isn't brand-new or hasn't been freshly formatted:

Tip: After getting the computer fully-patched, download/install KB971029 manually:
http://support.microsoft.com/kb/971029
NB: Any Norton or McAfee free-trial that came preinstalled on the computer when you bought it will be reinstalled (but invalid) when Windows is reinstalled.
You MUST uninstall the free-trial
and download/run the appropriate removal tool
before installing any updates, Windows Service Packs or IE upgrades
and before installing your new anti-virus application.
     Norton Removal Tool

     McAfee Consumer Products Removal Tool

If these procedures look too complex - and there is no shame in admitting this isn't your cup of tea - take the machine to a local, reputable and independent (i.e., not BigBoxStoreUSA or Geek Squad) computer repair shop.
Best of luck.
Wish I'd had better news for you.
