I have investigated this. It uses a Java exploit which affects 6 Update 30 or lower using "Pol.jar" on the same IP.

Once that executes the Java downloads a .exe from the same IP and steals passwords and stored certificates on the infected computer. It may do other things but it also appears that the .exe is blocked from running in a Virtual Machine so is making investigation more tedious.

Done more investigating.

Breaking out of java with no user interaction:

It is the Zbot trojan that steals passwords stored on the system such as Outlook, VPN, internet explorer saved passwords etc.

It modifies your internet settings to reduce security levels.

To check if you have this bit of junk look in:
C:\Documents and Settings\USERNAME\Application Data

Using "dir /a" so you see hidden files.

Then look in each sub folder for a single .exe with a random name:
Directory of C:\Documents and Settings\example\Application Data\Arovo

20/01/2012 12:33 DIR .
20/01/2012 12:33 DIR ..
20/01/2012 12:33 262,696 epawsa.exe
1 File(s) 262,696 bytes
2 Dir(s) 11,232,079,872 bytes free

In my case, this was the junk.
Rename this file.


Re-scan with AV software.

Ask an expert if you are unsure.
