My sister's computer is acting up, I ran Spybot, Ad-aware, and Avast but something has still taken over her wallpaper. It's black and says: Warning! Spyware threat has been detected on your PC. Your computer has several fatal errors due to spyware activity. Your IP address in 184.108.40.206 (which is her ip, however when she's logged on elsewhere it still shows that ip) and via this address an unauthorized access was gained by another computer. It is strongly recommended to install an antispyware software to close all secutrity vulnerabilities. And I' not good enough with HiJackThis, or Window's machines in general.
