Start up method for most software... hit the start menu go to run then type "regedit"
press enter on the Hkeys do this for both current and local... on the left go through these fodlers.... Software,microsoft,windows,current version, and now u see folders that say "run" look in all of them "runservices" if u have it is when ur computer is online it opens those programs. "run" is usally where alot of prorgams start up when windows starts. Make sure u know what u deltet to the right when u click the run folder... i can not stress enough this is the backbone of ur computer..lol well this is off the top of my head so enjoy if ur onfused think harder and spend time with it. also u can go to add remove programs to look for adware that tried to acess the internet. u could get a firewall also and make it listen on port 80 to see. sometimes prorgams listen on port 80 to go through firwalls..lol just another random thought late
