Well, since im the only computer expert in my family, I am tasked with handling any problems that may occur on any of the 7 computers in my house along with my brother's and sister's random friends' computers. So my sister's friend wants me to take a look at her laptop which I guess is being really slow. What I planned to do to it was defrag (which im sure has never been done), registry cleaner, and spyware removal. Now, I dont have an anti-virus that I can put on there so shes out of luck with the numerous viruses that im sure may inhabit her laptop. Do you guys suggest any other programs that I should run on it?
