ALT+F10 not working

windows XP home edition

And F-12 won't take you to boot sequence? Assume you tried the basics, such as battery reset, remove reinstall, reboot system? These would be the first things to try, if to no avail you'd be looking to get or create (from another system) a boot disk for Windows XP.

I apologize I believe it is a Trojan would you still be able to help, and yes I can change the boot sequence

If you can boot into safe mode, you might have a chance, if it is a bug creating the issue but you didn't say IF you are able to get to safe mode, specifically safe mode with networking.

I am unable to boot in any safe mode, however I will attempt to use avg rescue cd, do you have any experience with this if so could you guide me?

also yes I do believe it was a virus

It seems odd that you can get to bios or settings but can't access safe mode, F-8. As I said before, you could create a boot disk, from another computer or create a Linux boot disk, again from another computer. Another OLD trick is to get your hands on an older , 2004 or prior, Norton A/V disk, they had boot capability built in. You could try the AVG disk but I wouldn't bet on that unless you had AVG installed as a package.

Would you be able to guide me using a boot disk of your choice?

There are several tutorials on line as to how to create a Windows XP boot disk, you need access to another on line computer, go to a search engine and type in "How to create Windows XP boot disk" follow the basic instructions. If you are not computer savvy, most techie shops could create one for you, at a cost, of course.
