I live in Australia, where there is a monthly usage limit. Recently, once in a few days (around 5) there would be a huge upload, ranging from 1GB up to 10GB. Now it got even worse, and there's an upload nearly everyday. I now plug out the modem when the internet slows down (as bandwith is being used). I am using a wireless network. A few days ago, while the internet slowed down I checked the DHCP Clients Table, which showed only two computers connected, which is the amount there should be.

I have one suspect, gdrhost.exe, which HijackThis didn't recognise and it's marked by some websites as a backdoor virus. In cmd, I entered a code (I believe it was netstat) and it showed it was connected to some IP address.

Thanks!

P.S. McAfee scan clean, no p2p software, no torrents

Also, I am unable to get new Microsoft Updates. I'm not sure since when it's happening, since I just tried updating now. [Error number: 0x80070424]. No automatic updates as well.
I looked it up, and I was able to fix it (Look here for instructions).

This is starting to get interesting. Windows Malicious Software Removal Tool removed Backdoor:Win32/Rbot.gen. Could've this been the cause of all this?

Windows XP SP3, mainly using Firefox 3.0

It certainly sounds like you have malware on your system. Perhaps you could run HijackThis and post to that forum thread?

Hello,

I see that you have now posted a HiJack This log here: http://www.bleepingcomputer.com/forums/t/235565/huge-upload/ Now that you have a log posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond. Please be patient. It may take a while to get a response but your log will be reviewed and answered as soon as possible

To avoid confusion, I am closing this topic. Good luck with your log.

Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
