I can't restore desktop to factory settings

[JL2008]

Hi,

I am trying to restore my friends desktop. He has an HP desktop with XP. I press F11 during bootup. I then chose the option to restore to factory settings. I click on Yes. And then less than a minute later, it says restore is done, to make sure there is no CD in the CD drive & to restart the PC. I restart the PC and logged in. The restore didn't work. The 1st time I had a CD in the drive. The 2nd time, I didn't have a CD & the restore still didn't work. I tried System Restore and the earliest I can go back in September 1. Could the hard drive have a virus that would prevent me from restoring to factory settings? My friend is going to run Malwarebytes tonight. He ran MCfee and it said it found 1 threat. When I clicked on fix it took me to website where I have to pay to upgarde Mcafee. Please help us.

What HP desktop model, OS and kind of Windows CD(label) you are using? If your antivirus is expired, uninstall by their removal tool and download a free version. http://windows.microsoft.com/en-US/windows/products/security-essentials/download the newly installed will make a scan for any residing virus. Malwarebytes should help remove other infections, depending on how severe you are infected.

We ran malware bytes and it found 14 viruses. We also ran CC cleaner and deleted some stuff.  Then I found the HP Recovery software via Start>Programs. I restarted the PC and it took me to the same screen that F11 took me. I chose restore to factory settings and this time it worked. Thank you to everyone for responding.
