Downloading from Internet

[PBS]

I have no active applications that need to download from the internet, however there is constant traffic being downloaded.

the only active programs are those required by Windows XP Pro.  I have switched off Automatic updates for Windows and Avast.

I have the latest updates for both.  I did a scan but no viruses were found.

I use a Celluar connection for Internet access.  I have swopped with another user, the problem is only on the one pc.

I suspect a virus/malware, but as Avast does not find anything I'm a bit lost.

any ideas?

I suggest you use a two-side (inbound and outbound) firewall:

Online Armour
PCTools
Outpost Firewall Free
Comodo
ZoneAlarm

Personal Firewall Tests & Results. Firewall rating:

Also, you can use TCPView for Windows v2.54 to know what is running into Internet

You can upload the files that want to use the internet to VirusTotal to see if its a virus or not.
