Why is my internet slow?

download crap cleaner from ccleaner.com,and get a new free antivirus called avast from avast.com then delete your old anti viris software

you don't have virus or trojan? r u sure ?
so use ashampoo firewall in ur pc.
most of viruses try to connect net via explorer.exe then block all of them.

Try disabling unwanted things from Start-up.

Click Start -> Run; In the Open box type msconfig and then click on OK or press Enter; Select the Startup tab; Locate the start-up entry you want to disable.
