Virus killing all application on both dual booted win OS

[comda]

Greetings CH!

Last week i downloaded some sort of Virus that has terrorized my system. Ill boot into windows 7 Ultimate and i get all my login applications showing ".... has stopped working" and every program i try and open is the same thing. ON the windows XP partition i open an application and get "...has encountered a problem"

So i don't care much for trying to get rid of the Virus. Im going to do a clean install as it needed one anyways.
What im concerned about is the files and folder that i have on the drive.
I have a Sata To usb kit i wanna use to transfer all the stuff i need to my macbook and then back to my restored PC. However i want to be sure that the virus hasn't infected any of those files. What piece of software would work for me? I have another PC laptop i can use it on if the whole mac/Pc software is an issue.

Just wanna scan my stuff (preferably free) to make sure no virus is in it.
Let me know thanks

Your best bet would be to save you important data to DVD-RW's which can be reused afterwards and scan them with two good Anti-Virus programs before putting them back on the re-formatted computer.

Ok but which program can i use super dave? I have no anti virus and therefore i dunno which one to use to check the files hence the point of this thread.

It's dangerous to go on-line with no AV on your computer. You're just asking for trouble.

Remember to only install one antivirus!
 
1) Avast! Home Edition
2) AVG Free Edition
3) Avira AntiVir Personal
4) Microsoft Security Essentials for Windows Vista\Windows 7 - 64 bit Download
4-a) Microsoft Security Essentials for Windows XP
5) Comodo Antivirus (Uncheck during installation "Install Comodo SafeSurf..", Make Comodo my default search provider" and "Make Comodo Search my homepage" if you choose this one)
6) PC Tools AntiVirus Free Edition

It is strongly recommended that you run only one antivirus program at a time. Having more than one antivirus program active in memory uses additional resources and can result in program conflicts and false virus alerts. If you choose to install more than one antivirus program on your computer, then only one of them should be active in memory at a time.
