You could try a torrent site, but be careful some torrents will have viruses attached. A good anti-virus program will catch 90% of them. Also usually when you by software online that you have downloaded you can re-download the program again. Another way to do it would be to borrow it from your local library. Hope on of these ideas helps.
Good Luck!

There are 3 well known anti-virus softwares

1. AVG
2. Avira
3. Avast

I recommend Avira, but it really depends on your own experiences of use. So try one and have a secure PC :)

Use a good anti-virus software. There are many free ones, like the very popular AVG Anti-Virus Free Edition. Also, the Avast! Home Edition and Windows Defender are great. You can also try the Microsoft Windows Maliculous Software Removal Tool.

The downloads are available at CNET Download.com and the last one is a special program available only at the Microsoft Download Center. It has to be downloaded, used and then removed from the PC. It is updated every month, so you need to make sure that you use it every month after downloading from the site.

To prevent damage, later on you must have backups of the files on your PC, either on hard disks or DVDs. You can use a back-up software like the preloaded Windows Backup and Restore Center available in Windows Vista. You can also copy your important software and data manually onto these media.

Don't backup now, or you are going to backup the virus too (if it is really there) and waste your time. Remember, the virus cannot do anything while the computer is switched off.
