How can you improve my CPU usage percentage?
The question is not how to lower cpu usage but to either use less cpu (close background processes) or to smooth it out (I cannot find a way to do that no matter how hard i search). I find that it is not always the amount of cpu usage that is the problem but the way it is used. Windows has many pointless services built into every PC that runs it and they are all automatically set to run (such as wmpnetwork, etc.) if you want the best out of your computer i recommend following theese steps:
1. download a registry cleaner (I use CCleaner)
2. clean all temporary files and defrag, obviously :P.
3. disable unused appearance and ui features (you should know how to do this if not google it), i only disabled the shadows and animations because the rest just looks cool.
4. REGISTRY TWEAKS/MODS (google search it and you should come up with tons, they almost all improve performance or ui).
5. delete unused programs (we all have them, you can't deny it).
6.go to %temp% every once and a while and clean out what is left behind by the temporary file cleaners, if any file cannot be deleted then just click skip.
7. if you run firefox then this tip will really speed up your browsing... just as an extra tip. google for about:config mods/tweaks.
8. I reccomend this program by bitstrum called Process Lasso, it monitors every process, how much cpu usage, ram load, and virtual memory your computer is using and allows you to set permanent priority levels and throttles for every one. it also has a process watchdog allowing you to say if _______ is using ______% of ________ then ________. it comes witbh a tool called probalance witch sort of can try to work to balancing your cpu usage and responsiveness too!
9. This tip really helped me make my laptop so much more responsive, but it changes windows default memory usage. go to command prompt and type FSUTIL BEHAVIOR SET MEMORYUSAGE 2 (this will require a restart)
as some extra tips i will say right click your hard drive and go to properties, go to tools and start a disk check. it will prompt you to postpone it to the next startup and on the next startup it will open all MSDOS style and take a bit of time to do a full checkup. I find that this is not often usefull but you can try it if you want. another is to make sure your computer is NOT indexed... indexing may increase speed of searching but it deteriorates speed of the overall pc.
I hope this was helpful and i would like to note that this is my first time using answers.com...

What is a Trojan horse virus for computers?
When downloading Trojan into your PC, it would be would present itself as a useful software at the start. This will literally damage your computer as soon as it has been installed into the system. Some people would receive and start installing the software; this is tricking the user into opening the program. What this does is, it could automatically change your desktop, putting unnecessary icons up. This software can fatally affect your computer by deleting files and damaging your files and folders on your system.
The term Trojan Horse for malicious software comes from the legend of the Battle of Troy. The city was impenetrable, so the enemy could not get in the conventional way. The gates were guarded and the guards would never knowingly let enemies inside. So the enemies got clever. They created a huge horse statue which they hid inside, and the city thought it was a gift and brought it inside. Then the enemy soldiers climbed out of the statue at the right moment and started killing. Then they probably opened the gates and let the rest of their men inside. So just like this legend, malicious software authors would create something that seems useful or entertaining, and the users would run or install it and either lose files or get infected with a computer virus.

2 examples of way in which computer and people are effected when computer are hacked?
Depends on what kind of hacker you are. There are three types of hackers: white hat, grey hat and black hat.
White hat hackers are hackers you are given permission by people to test the security of their computer systems. For example, the government or some important business might hire a hacker to see how vulnerable their computers are. The hacker is given the permission to run some tests and that is all. These hackers know when to stop and NEVER do anything criminal at all.
Black hat hackers are the hackers who are malicious and evil. They are the people who write viruses and other types of malware to deliberately enter someone's computer system illegally and steal their confidential information like bank account information. Being a black hat hacker can get you into some serious trouble if you are caught. The Computer Fraud and Abuse Act has the authority to prosecute black hat hackers and sentence them to prison. This act not only makes it a crime to attempt to hack into someone's computer without permission, but also to conspire to do so.
Grey hat hackers are a mixture of both a white and black hat hacker. Grey hats are generally good people, but they will also do bad things time to time. They are hired by people to test their computer systems, but will do malicious things to run tests like infecting the system with a virus or such. Sometimes they will deliberately leave the virus there on purpose just so they can monitor the computer even though the client hired them out of trust. Grey hat hackers can be prosecuted just like a black hat hacker.
