Win 7 Java issue

Greetings have an issue that NEEDS professional opinion!

In the past, I've had little errors here & there but didn't do anything but slightly annoy me. Once again Java tries to start up using something from a random site an keeps saying "could not start" an below it is just a png file or something else, I always thought nothing of it. An every time I did get any real problems, I'd just run Combofix to fix the problems. But now, just recently Java tried to start again an failed again an instead of immediately pressing "ok" so the java thing will turn itself off, I opened taskmanager > Processes and found a very weird named exe file running in the background called "ajnkyhusjmo.exe" an I found it by right clicking it > Properties an looking at it's stored location which was "AppData\Local\Temp\fueyjpfvk" before I deleted it from my computer.

Yeah I got rid of a minor problem that had potential to kill my PC, but do you guys think I'll have more problems like this?
Also, in an effort to stop Java from launching another random program, I deleted the file javaw.exe (it was in taskmanager when the other exe was there).
my current Java is Java(TM) Platform, Standard Edition Runtime Environment V6.

So any thoughts on this would be helpful, I am going to run Combofix again just to be sure there is no viruses or whatever on my computer.
