Java stuff

Useful for WindowsXP when the system requires quick-start access to Java operability. That's what JQS means: Java Quick Start! It was added to Java in release Java SE 6 update 10. Not harmful but probably pretty pointless for Windows7 and above, as these newer systems come with their own Java prefetch anyhow. On WindowsXP, if you're tight for CPU cycles or the extra 20MB RAM just deactivate it... START CONTROL PANEL (you might need to "Switch to classic view" in the top-left) JAVA (click on the icon) ADVANCED (click on the tab) MISCELLANEOUS (you'll need to scroll down) JAVA QUICK STARTER ...simply uncheck the box! You may want to restart your system once this has been done, just to be clear. Hope this helps any confusion and makes you feel safer about this JQS.EXE file. It's not harmful, just a bit of a performance drag if you're not on the web.

Another automatic annoyance, but seems little more than that. Any Java update/upgrade will bring it back, and you have to go kill it again from the autostarts and Java controls and Explorer autoloads.
   
jqs.exe is the Java quick starter. It doesn't do much harm, but it does access the disks a lot. How to disable jqs.exe for all users of a computer: Press the Windows and R keys at the same time to bring up the Run command (or click ‘Start’ and then click ‘Run’) Type services.msc and press OK to load the Services configuration window Scroll down the list of services until you find ‘Java Quick Starter’ and then double click it to open the Java Quick Starter Properties window In the General tab, change the ‘Startup type’ from ‘Automatic’ to ‘Disabled’ then press the OK button Close the Services window – after you next restart your computer jqs.exe will be disabled and will no longer run, whereas doing this via control panel doesn't always work.

According to Oracle and java.com, Java Quick Starter pre-loads about 20Mb of files in memory, which makes Java start-up considerably faster. If you visit web pages that use Java -- like many games, multimedia sites, etc., such as RuneScape or the U.S. government's official time page -- jqs.exe will help these pages and applets load much faster.

Also, this link will tell you how to disable JQS, if you really want to -- if you are running on Windows Vista/7/8 (or better, in the future), these versions of Windows have their own pre-loader for Java and other programs; however, Windows XP and 2000 benefit a great deal from JQS, and it doesn't take up very much space, so I'd recommend letting it run.

stepped into a smelly exe, and next thing I see is a brand new jqs.exe hitting 95% cpu. Removing it seems hard. Removed Java altogether, disabled java browser plugins, removed all related files.. Keeps coming back. Quiet when network is disabled, very busy when not. Do not know about your file, but mine is definitely a virus. 1.114.112 bytes on disk.

I got qurious when I saw in the task manager that it had accumulated a very high count of bytes read. More than 30 times more than the second ranking process
