my brother has recently downloaded something and it is freezing up my computer/internet. my internet connection is very very slow and disconnects from time to time. my computer in general has been very slow. i downloaded mozilla firefox thinking it would make my connection a bit faster but it didn't and started giving me random pop ups. i don't know what to do. do i need to reformat it because i want it to be like how it was when i first bought my laptop. please help me!!! i also get trojan.vundo, infostealer, WinFixer, MisleadApp, trojan.Metajuan, and DriveCleaner on my Norton Antivirus. i just got a tracking cookie on my norton scan. risk is low
