K.A.
The first thing you will have to do is clean the laptop of the virus. You will not be able to install an anti-virus program directly from an internet download, you will have to have a disc in order to go around the virus. Transfering the pictures will transfer the virus on to any further computers that you use those pictures on. Secondly, I also recommend an external Terrabyte drive. 1000 pictures is more than a CD or flash drive will hold unless they are very small files, which I doubt.
It really depends on how comfortable you are working with a computer. If you feel pretty comfortable than it is something you can do yourself. If you are not I highly recommend paying a professional to save your pictures. Memories are worth a small price to save IMO.
