Hi again.
If you do have a system image, restoring it is probably the easiest way to recover your computer.
I'm guessing that you don't, not enough people do this.
If all ease fails you could try saving your photos by creating a Ubuntu disk on another computer and using it to boot your computer.
It should give you access to your files and let you copy them to an external hard drive or to DVDs.
I did this successfully when my wife's sister's computer was infected.
We were able to save her files to a DVD before using a factory reset to clean her computer.

If you don't have a 64 bit computer make sure you select the 32 bit version.
The 32 bit version will work on either 32 or 64 bit...
