Indexing services in Windows VISTA

Disable search indexing
The indexing service in Windows Vista is a lot more useful, given the presence of the searchbar. It's still not essential though, and it still uses up hard disk and memory resources. Disabling the indexing service does not disable the search or search bar functions of Vista, but it will slow down the results a bit. Disabling it will speed the rest of your computer system up a bit, so the trade off is up to you.
To disable the Windows Vista Indexing service:
Open the 'start' menu and type 'services' in the searchbar. Hit Enter.
In the services window, scroll down until you reach the 'windows search' service. Right click it and hit 'properties'.
In the 'startup type' dropdown box, change the value to 'disabled', then click the 'stop' button below to stop the service immediately. Hit 'ok.'

How to tell if your computer is infected with spyware
Spyware is a type of software that is installed on your computer to watch and record your activity. Some types of spyware record your keystrokes and information that you type into websites or other programs and then use that information for targeted advertising or identity theft. These programs can be installed on your computer in many ways but often they are hidden inside of software such as free games, screen savers, or animated cursors.
Here are some signs that your computer might be infected with spyware:
You notice new toolbars, links, or favorites that you did not intentionally add to your web browser.
Your home page, mouse pointer, or search program changes unexpectedly.
You type the address of a specific website into your web browser, but you are taken to a completely unrelated website.
You see pop-up ads, even if your computer is not connected to the Internet.
Your computer suddenly starts running more slowly that it usually does. Not all computer performance problems are caused by spyware, of course, but spyware can cause a noticeable change in processing speed.
Sometimes your computer will show no symptoms, even if a spyware program is running. To help protect your privacy and your computer, we recommend that you run Windows Defender or another antispyware program at all times.
