No, the anti-virus wasn't the solution, my hard drive completely died, it even says that it fails when I turn it on.
And my friend just goes on my PS3 when I am not home.
So you're saying the IDE Timeout error code comes to the corresponding port in which the hard drive is located (SATA1, PRIMARY MASTER, etc.)?
Check to see if your cords on it are unplugged slightly, pushing on the cords going to the HD should work.
If not, all your data on that drive is lost.
also why does your friend get to use it when you're not home
srsly wtf
