There are many ways to protect your computer against usb/flash viruses.
1.Don’t use usb/flash drives
If you will not use any usb/flash drive then there is no chance you will get usb/flash drive viruses.

The openness of the Internet has dramatically transformed global communications, making it easy for people around the world to exchange information. But the very same openness also creates an enormous problem. Anyone can access the network, yet not everyone has good intentions.
Some engage in malicious mischief by unleashing destructive software programs, while others view hacking computer networks as sport. Then there are people with criminal goals in mind.
To avoid becoming a victim of misguided pranksters or cyber-crime, take the time to examine the security of your personal data. Here are our recommendations, along with links to more detailed information:
1. Use anti-virus software:
Viruses spread rapidly and can damage or destroy your computer. New ones appear almost daily. It’s critical that you install and update anti-virus software regularly. Use the program to scan all the files on your system once a week, deleting the infected ones. I use avg free edition, you can get it from http://free.avg.com
2. Beware of e-mail attachments:
A virus can hide in an attachment. Opening it will unleash the virus. Don’t open an attachment from anyone you don’t know. Even if you do know the sender, an infected attachment may have been surreptitiously sent from an infected machine. The safest thing to do is to scan the attachment with anti-virus software before you open it.

Then install IIS on vista and enjoy IIS 7.0 but make sure your computer can run XP and VISTA, both at the same time.

This error occurs when IIS is not installed completely i.e. You’ve install IIS but asp.net isn’t installed and by default asp.net doesn’t install automatically so you have to install asp.net.

Microsoft has admitted that speech recognition features in Vista could be hijacked so that a PC tells itself to delete files or folders.
Vista can respond to vocal commands and concern has been raised about malicious audio on websites or sent via e-mail.
In one scenario outlined by users an MP3 file of voice instructions was used to tell the PC to delete documents.
Microsoft said the exploit was “technically possible” but there was no need to worry.
