Ok I wrote this guilde for the mmorpg called "Tibia" but this will work just as well for protecting your computer and just making it a tad bit faster hopfully it will help out.

Well lets start this off first thing is to open internet explorer and then go to this site http://www.mozilla.com/firefox/
Once there download fire fox and install it this will be your new browser to use the internet on. It is faster and easier to you and understand its a combination of Netscape and Internet Explorer. So after that to make you fire fox go faster follow this guide
Here's something for broadband people that will really speed Fire fox up: 1.Type "about:config" into the address bar and hit return. Scroll down and look for the following entries: network.http.pipelining network.http.proxy.pipelining network.http.pipelining.maxrequests Normally the browser will make one request to a web page at a time. When you enable pipelining it will make several at once, which really speeds up page loading. 2. Alter the entries as follows: Set "network.http.pipelining" to "true" Set "network.http.proxy.pipelining" to "true" Set "network.http.pipelining.maxrequests" to some number like 30. This means it will make 30 requests at once. 3. Lastly right-click anywhere and select New-> Integer. Name it "nglayout.initialpaint.delay" and set its value to "0". This value is the amount of time the browser waits before it acts on information it receives. If you're using a broadband connection you'll load pages MUCH faster now!

Ok now that is done your internet should be going a lot faster so next is to get off all those pesky viruses and spy ware
For spy ware use this program it is free and works 100% guaranteed
Click on " USA Major Geeks TX - |USA| "
After you download and install it donít run it yet because you need to get a new virus protection I use AVG Free Edition 7.1.375
Click on " USA Major Geeks TX - |USA| "
Install that and you are almost ready to start running the stuff
the last thing you need is a fire wall I would use this Outpost Firewall Free 1.0.1817
Click on " USA Major Geeks TX - |USA| "
Install that and you are ready right? No you are not you must do a few other things before you run anything.
One thing is to open add or remove program files to get there go to
start>control panel>add or remove programs
once that is open look for programs that you do not use and that you installed. Make sure you don't delete a windows file or there goes your computer and I will not take responsibility of you deleting a windows file when I said not to.... so anyways deleted everything that you donít use or never plan on using it. Then close that window and go to this
start>run>type in "msconfig">startup
after you are there look for programs like windows messenger, yahoo messenger, or msn messenger or any other type of messenger. Also close real player and any other bs programs that you see running when you turn on your computer. Then press ok and you will be asked to restart your computer just press exit without restart for the time being.
--Update-- Another thing you can do is go to start>control panel>performance and maintenance>system>automatic updates and switch it to notify me but do not download or install them cause if windows just starts downloading 100 mb for the newest update ya you will massive lag no matter who you are so just be on the safe side and let them notify you when a update is ready so you can safly log off and be ready.

If you are using internet explorer you can clean your cookies to do this open internet explorer, tools, internet options, open the general tab, and select delete cookies. ( it is almost the same in any type of web browser you choose using internet explorer cause everyone has it)
credit for ie cookies goes to -----Great lord of . . .

Now you are ready open up ad-ware se personal and update it and run it after its done (will take some time) press next and click on the little box so it puts a check by the red or orange bubble make sure you get all of them especially the red ones. Then click next and your spy ware is gone. For avg follows the same steps almost so just follow it. and for the fire wall just set it up. So now all you have to do is restart your computer and see how much faster it runs with all that stuff off of it.

Warning-if you deleted something that you shouldnít then its your own fault and you can not blame me or try to sue me cause I won't pay for something that you did on your own. So ya hope you guys like this guide and if you screw your own computer then its your own fault.
