My internet speed dramatically reduced for some reason, what gives?

I went to speedtest.net and it went from like 1.3Mbs download speeds to like 190kbs download speeds and I can also notice it when I try to download music on iTunes. I don't know what happend, it just started being slower overnight. any ideas? My upload speed went down too, but not so drastically. I ran my anti-spyware, anti-ad ware and ant-virus software and can't find anything. I think it might have something to do with a java download, but I'm not sure, how can I find out?

if your internet is wireless, make sure that there arnt any signal obstructions, like microwaves, wireless phones, metal walls, things like that. if it is wired, try doing a system restore, it is something where you specify a date where everything was fine, and it will take your computer back to the condition that it was, but if you have important documents, back them up on like a flash drive or something. because a system restore will delete them in order to get back to the previous condition. hope this helps!

Some internet connections are semi-shared. Meaning if your neighbor is also downloading a lot then you suffer. If it continues call your provider and tell them you are gonna switch providers unless you recieve something more like the advertised internet speed.
That's pretty extreme. If you have a firewall turn it off and do the test. If you have more than one spyware/ativirus program turn off the extra ones.

Clear you internet cache and cookies, go to system tools and do a disk cleanup, and if you have a registry fixer run it.

Also it could be your isp, it's hard to tell but I really think you have too much junk running in the backround slowing down your machine.
you didn't mention doing a defrag of your system or a disk cleaning...you can find those things by clicking start, all programs, accessories and then in the dropdown you will see both the defrag and disk clean...once you run those, your speed should pick back up...
