Hi and welcome to the Daniweb forums :).

==========

Go to add/remove programs and uninstall every entry for Java Sun that is there. When done, go HERE and install the latest version.

==

Please download ComboFix by sUBs from HERE or HERE

• You must download it to and run it from your Desktop
• Physically disconnect from the internet.
• Now STOP all your monitoring programs (Antivirus/Antispyware, Guards and Shields) as they could easily interfere with ComboFix.
• Double click combofix.exe & follow the prompts.
• When finished, it will produce a log. Please save that log to post in your next reply along with a fresh HJT log
• Re-enable all the programs that were disabled during the running of ComboFix..

Note:
Do not mouse-click combofix's window while it is running. That may cause it to stall.

CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run. If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.

This worked thanks for your help

I need to see the log. There is more to do. Combofix makes changes to your system that need to be changed back when it is no longer needed.
Instructions are for a reason :)
