I doubt this caused a virus to vista



Vista uses something called UAC which essentually controls users. No user is a TRUE administrator and that was the start of your problem



It is possible to shut off UAC which is what I have done...go here to learn how

Vista does not have a virus in it. Millions of people use Vista and are content with it.

Your idea to dump Vista for another OS simply because your computer got a virus is like crushing your car because it ran out of gasHow to change my operating system?
Run Vista in safe mode. Install Malwarebytes - http://www.malwarebytes.org/mbam.php - and let it run to completion. Then you'll be able to run Vista normally.



Then download and install Avast - http://www.avast.com/eng/download-avast- and keep it running to avoid virus problems.



(Downloading a %26quot;free%26quot; copy of Windows 7 is a great way to get a virus or 10. If you want 7, if your computer is eligible for the free upgrade, see whether Toshiba is still taking applications - they were supposed to be made by January. If not, you'll have to buy the upgrade.



As far as the message you're getting, post the EXACT message - in computers, where one letter makes a lot of difference, posting your interpretation of an error message is useless.)
