I'm running Win XP Home and AVG Anti-virus 9.0.864. Due to viruses that seem to be incurable, I'm getting ready to wipe and reformat my hard disk, then reinstall Win XP Home, and all my other software. My email (Thunderbird) files are very important to my work - I would like to save them on flash drives then put them on the cleaned up hard disk. If I do this, will I be taking a chance on bringing back the very viruses that are now causing me problems?
