|Viruses don't get embedded, you just have to know how to remove them. I supplied links to 4 excellent anti-virus & anti-spy programs, did you try any of them? Which program do you normally use?|
I assume what you have planned is to completely wipe the hard drive & start from scratch? That means you will lose everything! So hopefully you've already backed up all your important documents, photos, videos, etc. And make sure you have backup copies of all your software & device drivers because they won't be on the XP disk. And what drivers are on the disk will be close to 10 yrs old. Also, if you have a SATA hard drive, reinstalling XP is a bit tricky. Hopefully you've looked into all these things.
To find your product key, use a program called Magical Jelly Bean - google will find it for you.
