how to detect a system is hacked (and now,is a zombi)

[saeidmscs]

Hello every one.
nice job.
I use 128kbps ADSL to connect to the Internet .About one weeks ago,every thing was O.K. and download speed was as usual.
But now,the download and surfing speed is significantly reduced and the download speed is 48kbps
I don't know why,but I think because of using torrent protocol(to download a file),my system is hacked and is a zombi,now.
I have checked all process by Spyware Process Detector,but nothing is unusual(at least,as i know).

Any ideas about such reduced speed,friends?
If the system has become a zombie,how can i rescue it?

Thanks in advanced

You may want to have a in depth look at your internet connections with this tool & do some investigating.

TCPView for Windows

TCPView is a Windows program that will show you detailed listings of all TCP and UDP endpoints on your system, including the local and remote addresses and state of TCP connections. On Windows Server 2008, Vista, and XP, TCPView also reports the name of the process that owns the endpoint. TCPView provides a more informative and conveniently presented subset of the Netstat program that ships with Windows. The TCPView download includes Tcpvcon, a command-line version with the same functionality.

Download/upload speed can fluctuate due to other problems. The speed for my entire area was reduced to a crawl a while back for about 3 days until they fixed a server problem in the next town.

The tool is free, use it see if you have an excessive amount of connections.

Also, it wouldn't hurt to run a scan with Malwarebytes:

Dude using torrenting software/torrents doesn't give you any problems or viruses. It what you download that puts you at risk. Try running a MBAM scan for any viruses.
