What do other computer users say about jqs?
|This is a valid program (further information...) |
|Just Java stuff |
|Java Quick Starter. Generally speaking it's not needed at all by normal users and is really only of benefit to people if you're using Java regularly, i.e: more than once per day. Basically it's aimed at those who use Java almost constantly for whatever reason. There is no harm in doing an 'End Process' on it or alternatively under Start Control Panel Java then Advanced tab and the 'Miscellaneous' section it can be disabled there by un-ticking the relevant tick box. Saying that, it was found to be running as a system process even though I didn't have the box ticked to enable it. |
