I have a problem

My computer seems to be downloading on it's own. I've been downloading a torrent, it was averaging on 20KB/s, which was adequate, but now averages on 2KB/s

Watching the bytes downloaded in task manager, it seems to be downloading at 25KB/s, and I am on a a less than speedy connection, so this seems to take over my internet.

I recently discovered that I had a worm called 'sasser' so to be cautious I did a complete reformat, but backing up important files beforehand.

But since the reformat, it seems to have gotten even worse. I have Zonealarm in place, and in 2 days, it has blocked over 16,000 access attempts.

I have run AVG, bazooka and adaware, and they've returned nothing. I was wondering what the best tool/method would be to work out what I have, or how to go about beginning to correct it.

Try this, Download Avast Free to your desktop, disable your present AV, install Avast and let it do a bootscan on reboot. Move all it finds to the chest.
There are also lots of good free programs in the red link listed on 1 page with basic instructions. I would suggest running those also.

Some HELP in posting on Cnet plus free progs and instructions Glad to Help!

Last night, in waiting for a reply, I started having a look at other posts, and have already installed all those programs. But I'll definitely try a bootscan on reboot.

Thanks

Done, and unfortunately, this too returned nothing

This free online scan might help you:

I ran the scan, and it picked something up, something called Switch Dialer. I got rid of it, and restarted the computer. Comodo is still reporting access attempts though.

As a matter of fact, this is one of them. Im not sure wether it is to be trusted or not:
