Malware, the Web Bots and Trojans is equal to the fall of DSL speed?

Ive been having some trouble DSL speed and my ISP suggested that my computer had been compromised, so I downloaded Microsoft Security Essentials and of course after a 5 hour scan he found a Trojan horse and removed, although later that night, I continued to have speed issues, the provider advised me to use CMD and run a Netstat to see what was using my DSL if anything. Im not for techies, but I found these lines a bit curious to say the least:

(TCP 192.168.254.1:49263 yx - in - f139:http TIME_WAIT)
TCP 192.168.254.1:49266 lasvegas-nv - UNOFFICIAL datacenter:http
TCP 192.168.254.1:49268 213.174.154.144:http CLOSE_WAIT)

I googled the lasvegas and the yx but I have found no information in their regard. Any help to what they are or how to fix this would be appreciated.

Hello

The suggestion recommended for this problem would be to perform a new installation.

Important: Data and the applications on the computer will be lost after a clean install. Make a backup of your data before performing any installation.

The following steps are worth a try:

Method 1: Disable the firewall (security software) software and then test to see if the problem persists. Follow the steps mentioned in the link below

Disable antivirus software

Enable or disable Windows Firewall

 

If you use a non-Microsoft security software, you can check the documentation provided with the program to achieve this.
 
Important:
Activate the Security (firewall program) software once everything is done.

Method 2: Put the computer to point earlier in time where everything worked well until the computer has been infected by the virus and then run a virus scan again and check if that makes a difference

Follow the steps mentioned in the link below to complete the restore of the system
