I think I am still infected

A few weeks ago, I got the nasty virus of Home Antivirus 2010 (I think) I found the Read and Run post and I think I followed everything to a T. I did not post my logs because after running everything I thought I was clean. Now, I am having issues with installing Microsoft Office Student and Teacher Edition 2003 on the same computer(OS is Windows XP Home) Where do I go from here?

 

Ok, so this morning I woke up and had an epiphany. eMachines have a System Recovery built in. I don't know much about computers but I found the eMachines user guide and I printed out the 25 pages on system recoveries. I sat down and I spent an hour reading about and then deceided that it didn't look too hard or complicated. I got out my blank disks, as I do not have them from when the machine was purchased (the machine is actually my sister in laws from when she and her son were staying with my family~ hence why I am so adamant about fixing it and not just throwing it out the door as we already have 2 workable machines in the house) as I put the first cd in the slot to start the burning, my system went black, made a whole bunch of noises and then shut off. Now, I can not boot back into Windows and it is telling me to press any key to re-start the machine. I have tried F11 to no avail (it just starts Safemode) and I know that I can purchase a new OS and go from there as I contacted eMachines and they do not have the disks for sale anymore. I really at this point just need to get it back to the way it was when she purchased it or I will be the one buying her a new computer. I have looked at websites regarding the disks but they all seem really shady. Does anyone have an ideas how to either get back into my system or to actually acquire the disks? I don't mind paying the money. It would really save me a headache and probably alot more money.
