Here's something I just found out recently. I use Advanced System Care. It has a feature with its Uninstall Programs that let's you see the add on's used in each browser that you have. I noticed I had 5 or 6 versions of Java. I uninstalled all of them. ASC does a power sweep of Registry and gets rid of all of that too. So now I have no Java at all and meter was smooth on any browser I used. Most people don't know that now a days you don't need any type of Java Program at all. If you do need Java for something, it will tell you that you need it. This was confirmed by a friend of mine that does support for Microsoft. Just an FYI.
Something else I found out when I did this was I had 2 versions of Shockwave Flash Player as an add on in Firefox. If I disabled 1, the other would automatically disable too. So that was no good. And you can't have both enabled or they will conflict and you get a terrible meter. Then the thing was, I couldn't uninstall them either. I had to go to the Adobe web site and download an Uninstall program for the flash player. Here is link:

Another FYI there are 2 types of Flash Player. One is, Active X version and the other is a Plug In Version. Depending on what Browser you use, only one or the other is used with that browser. And the only way to get the right version Flash, is to download Adobe Flash Player with that browser. That download will recognize what browser you are using and give you the correct version, either Active X or Plug In.
Make sure you download it from the Adobe website. And if you do download from their site or any other site, make sure you read what you are downloading. They all try to add another program or tool bar with the download. Read and uncheck them.
One thing that they like to get you to download with their software is a free anti virus. If you already have an anti virus program, having 2 will cause conflicts and really mess up your meter.

Look at this link. This is where you would want to download from. But look in the center where it says optional offer. They already have it checked for you to make Google Chrome your default Web Browser and giving you a Google Tool Bar For Internet explorer. At least that is what I see because I am using IE. There might be something different there if you are using a different browser. Make sure you uncheck that. That one way they try and trick you into downloading other junk. If you've got a bunch of toolbars at top of your browser, those are all processes running and will take away from he performance of your PC and specially your meter.
Be careful downloading. Always do the custom download. And read each page as the download goes on. when you do the custom download. Uncheck and decline any other program or software they are trying to include until you get to the install button.
