Slow Internet Connection / Netstat Extreme Stats / Loops

Avast Free Antivirus / Premium Security
1

Hi,

Recently, I have been experiencing slow internet connection and noticed it was only an issue on my computer. I have Cable connection with a router setup. My main computer is directly connected to the router and have one desktop and another laptop.

My two other PCs don’t have Avast installed and the internet from those PCs works fine.

However, my main PC where I have Avast installed is giving me this issue. And the strange thing is, I didn’t experience anything like this until recently.

I looked at /netstat and all these connections just threw me off. I read in another post at this forum that the Web Shield module uses port 12080 proxy or something like that.

I tried turning off the web shield but my speed did not improve. I also did a Virus scan/Spyware scan but still no luck.

Here’s just part one of the /netstat output.

I have Avast Internet Security / 5

Any advice? I could not post the whole netstat output because there’s 10,000 character limit

If all of your netstat traffic is basically the same it is all localhost 127.0.0.1 and not connected internet traffic (other than the last bunch which are local network).

So if this is the general format of the netstat entries, posting more is unlikely to give any more information. If it does, you can pipe your netstat command output to a .txt file and attach the file to the post using the Additional Options, in the Reply window.

The web shield uses localhost port 12080 so that it can scan http port 80 traffic.

As you say this wasn’t previously an issue, so I wonder what has changed. Unfortunately this isn’t something I’m very familiar with
