Just found a severe virus

I just ran a boot scan, after a few hours it found 7 infections. They all had very strange names.
And they were all in C:\Users*****\AppData\LocalLow\Sun\Java\Deployment
(The **** is my name)

Names like “padle.class”,“hubert.class”,“CusBen.class”,“Trollllllle.class”
And there was 3 others. They were all listed as severe and I moved them to the chest. Did I do the right thing?

(This is my first avast! forum post, sorry if it isn’t the way it should be or something.)

you can use secunia online scanner to check for outdated software with security risk

Uninstall Java.
Delete anything in C drive — WINDOWS files---- Downloaded programs.

Then reinstall Java .

The name given by avast! was:
Java:Agent-GP[Expl]

Now, it found 7 things like I said. And where it says “GP” was different on each one. E.g, the “Trolllllll.class” one was “EN” I don’t know much about this, hopefully you understand.

Java:Agent-GP[Expl]
GP is the version they found. Today we found a java exploit an we call it A, next day a new version is found and they call it B an when the hole alphabet is used the start from the beginning again, AA - AB - AC...... The Expl means it will exploit vulnerability in the java system and that is why you need to have latest version of java where those security holes have been fixed, then the bug cant do anything even if not detected

here is one example
