Virus going nuts uploading data?

[antonycarthy]

My Telkom ADSL at the new place I'm staying at is running pretty hot - check it out:

Monday 01/02/10:
Uploaded 397.4663 MB
Downloaded 77.1329 MB
Combined Total 474.5992 MB

As you can see the uploads are unusually high, especially as I've just been browsing the net - nothing unusual and no VOIP or anything.

This has been going on for the last month or so - since I moved in. I have 1 PC connected to the Netgear router and have the latest version of AVG Free, which scans nightly and hasn't picked up any viruses. I have tried to use Wireshark to pick up on what is doing the uploads, but there is just too much happening and I don't have time to try to understand what traffic is legitimate and what isn't.

Any ideas? Are there any nasty viruses out at the moment?

Download and install PeerBlock.

Download and install MalwareBytes.

Check active programs on firewall and stop all unknowns!

Any P2P software installed?

It's pointless running a scan once you've already been infected, as the AV may already be compromised. Run an ESET online scan and see if it picks up anything.

I just took someone else's infected hard drive and installed it in a external USB drive bay. AVG Free, Malwarebytes, Microsoft Security Essentials and some manual removal enabled me to kill the b@stard. It continually reinfected the original drive and any USB stick or network drives. AVG/Malwarbytes/MSE kept the virus at bay and stopped further infections whilst only a manual search and destroy killed the actual source generating seeds. I found the source seeds by looking at the key virus files in notepad and saw what the bugger was doing!

Anyway maybe use ProcessExplorer (Windows tools free) to determine who the culprit is.
