Let’s go easy, and start with the following…
If you have older and more vulnerable Java version(s) installed, you need to remove those and update to the latest version:
Before downloading, you need to know if your system is 32bit or 64bit:
To find out:
Click Start, and then click the key ‘R’
Type the following in the Open area: sysdm.cpl
Click the General tab.
The operating system is displayed under System as follows (examples):
For a 64-bit version operating system: Windows Vista Professional x64 Edition Version < Year>
For a 32-bit version operating system: Windows Vista Professional Version x32 Edition Version <Year>
Just note whether the system is 32-bit or 64-bit, so you can download the right file.
Now, go to:
Download the latest version of Sun Java [Java Runtime Environment (JRE) 6 Update 26].
Choose to download: Windows 7/XP Offline
Save to the Desktop, but do not run the file yet!
Now, go to Start > Control Panel > Add/Remove Programs and uninstall all versions Java/JRE (Sun Java Runtime Environment/J2SE Runtime Environment). You can only do this one at a time, if more than one entry is present.
When all done, restart the computer.
Then, right-click the downloaded 'Java Runtime Environment (JRE) 6 Update 26' file and select: 'Run as Administrator' to install the latest Java version.
Reboot when you are done.
Run your F-Secure viru scan, and see if it still picks up the malware.
Let us know.
