Hi,
If you decide to try to clean any malware we can have you start a new thread in Malware Removal forum and Close this one....or, if you want to get Recovery disks and reinstall the whole computer, that is fine.
Here is one other place to obtain the set, they are the same as HP ones
www.computersurgeons.com
You have to enter the family and model information, or you can call the number for help.
I would try the HP first as I have seen them cost only $17
and the other place is around $27
