If you are using any version of Sun Java that is prior to JRE Version 6.0,
then you are strongly urged to remove any/all versions.
There are vulnerabilities in them and they are actively being exploited.

It is highly suggested that you update to the latest version which is Sun Java JRE/JSE
Version 6.0

Simple check, look under...
C:\Program Files\Java

The only folder under that folder should be the latest version.

Such as...
C:\Program Files\Java\jre1.6.0

For non-viral malware...

Please download, install and update the following software...

* Ad-aware SE v1.06
http://www.lavasoft.de/
http://www.lavasoftusa.com/
http://www.lavasoft.de/ms/index.htm

* SpyBot Search and Destroy v1.4
http://security.kolla.de/
http://www.safer-networking.org/microsoft.en.html

* SuperAntiSpyware
http://www.superantispyware.com/supe...freevspro.html

After the software is updated, I suggest scanning the system in Safe Mode.

I also suggest downloading, installing and updating BHODemon for any Browser Helper Objects
that may be on the PC.

* BHODemon

http://www.majorgeeks.com/downloadge...4332b4b8b8442d

For viral malware...

* Download MULTI_AV.EXE from the URL --
http://www.ik-cs.com/programs/virtools/Multi_AV.exe

To use this utility, perform the following...
Execute; Multi_AV.exe { Note: You must use the default folder C:\AV-CLS }
Choose; Unzip
Choose; Close

Execute; C:\AV-CLS\StartMenu.BAT
{ or Double-click on 'Start Menu' in C:\AV-CLS }

NOTE: You may have to disable your software FireWall or allow WGET.EXE to go through your
FireWall to allow it to download the needed AV vendor related files.

C:\AV-CLS\StartMenu.BAT -- { or Double-click on 'Start Menu' in C:\AV-CLS}
This will bring up the initial menu of choices and should be executed in Normal Mode.
This way all the components can be downloaded from each AV vendor's web site.
The choices are; Sophos, Trend, McAfee, Kaspersky, Exit this menu and Reboot the PC.

You can choose to go to each menu item and just download the needed files or you can
download the files and perform a scan in Normal Mode. Once you have downloaded the files
needed for each scanner you want to use, you should reboot the PC into Safe Mode [F8 key
during boot] and re-run the menu again and choose which scanner you want to run in Safe
Mode. It is suggested to run the scanners in both Safe Mode and Normal Mode.

When the menu is displayed hitting 'H' or 'h' will bring up a more comprehensive PDF help
file. http://www.ik-cs.com/multi-av.htm

I have found the process responsible for the Port 53 traffic.
Suspending this process in Process Explorer stops the network activity.
Resuming it restarts the activity. Below are the details.

Stop spreading FUD!
1.5.0_10 as well as 1.4.2_13 have no known vulnerabilities!

It's completely sufficient to have the latest version of 1.5.0 or 1.4.2
installed and all previous versions (manually!) removed.
There are still quite some applets and java applications out there which
won't run with JRE6 or even JRE5!

When will you learn to use "%ProgramFiles%"?

Alun already gave the ONLY CORRECT advice: flatten and rebuild.

You should replace the six with a nine or ten.

I'm sorry Gabriele but Sun is f'd up and confusing.

v6 is the latest and based upon ALL the problems with Sun not being forthcoming with
Vulnerability statements, v6 is the suggested version. It is a complete re-write.

I did have older versions of JRE, J2SE and J2ME SDK and uninstalled
them as well as deleting all related folders. The problem is still
there.

As I mentioned before, I have run a few anivirus and antispyware
programs both in normal and safe mode and they haven't identified any
issues. Of course all software were properly updated before running.

At this poing I'm starting to consider reinstalling Windows XP.

Replacing Sun Java was NOT part of the solution for you.

Since there are so many vulnerabilities in older version, upgrading and replacing them with
the latest version will help mitigate malware which may exploit those vulnerablities and
help prevent future problems.

Plaese run the anti malware scans and software I suggested.

I'll run all the scans you suggested later today and post the results.

OK, I downloaded and ran all the software. While Ad-Aware was running I
get a warning from AntiVir that it had found a virus called
Run_it_xxx.exe. I deleted it. Other than that, they came up with a few
minor viruses on some files that have been on my PC for ever. I
quarantined them. I also made sure I have all the Windows security
updates, and I do except for a RAID driver. I also upgraded to IE 7
just to be sure. The problem still persists.

I installed a program called Prevx1 which seems to be a nice program.
It tells you when an application starts ends etc. Every time I
disconnect and reconnect the network connection, it tells me that a
program called MOBSYNC.EXE has started. I'm not sure if this is
related.

Also, the network connection seems to be active only at certain times
and inactive otherwise. When it's active it goes like crazy. I'm
suspicious that the PC is being used for DOS attacks or SPAM etc.

I'm still at a loss and any help will be appreciated. The only way I
can fight this is by unplugging the network connection.

Also, I recently configured reverse DNS lookup for my static IP address
through my ISP. Can this be related to the network activity?

MOBSYNC.EXE is most likely legit and OK.

This may have to do with the RDNS service.
