First let's determine what both can do for you and the benefits of having them. With these two kinds of programs, your computer will run fast and free from Trojans and Malware.
An Anti-spyware program is simply a program that detects and removes any virus, Malware, Spyware and Trojans on your computer. Some common type of problems with spyware are pop ups, home page keeps changing and programs that track where you go and can get sensitive material from you like credit card numbers. With an Anti-spyware program it can find these Trojans and Malware and remove them safely from your computer for you.
Here is list of the top ten common types of Trojans and Malware that infect your computer:
1. Trojan-Downloader.Zlob.Media-C
2. Trojan.FakeAlert
3. Virtumonde
4. Zango.CommonElements
5. WinSpy
6. Zango.SearchAssistant
7. SpySheriff
8. Command Service
9. 180solutions.SearchAssistant
10. Trojan-Downloader.Gen
If you have any of these programs than I highly recommend you get a Anti-spyware program to remove these programs before something bad happens.
Now with a Registry cleaning program it cleans and removes and unneeded entries in the Windows registry. What is the Windows registry? It is like a set of instructions that Windows looks to when starting and running software and hardware. And when this becomes corrupt and full of useless entries overtime it can bog down a computer or even worse it can crash a computer. With a Registry cleaning program you don't have to worry about these problems. It's a very good type of program to tune up your computer especially with an older computer.
When both a Registry cleaning program and Anti-spyware program are used your computer will run faster and more importantly safer than ever before.
