Depending on your preference, you can purchase a corded mouse or a wireless mouse. Wireless mice run on batteries and during heavy use, these mice can drain your batteries in a day or two.

Well I will try and answer this the best that I can. Basically a computer can consist of two broad categories, hardware and software and the way a computer works is between these two working together. I will oultine them both briefly below.
How can you protect the hardware? The first thing you can do is to purchase or download the reputable anti virus. It will be better for your computer. In fact, some companies provide/run the online virus scans for free. Some of the examples are such as Kaspersky and also Trend-Micro Housecalls. The important thing is about updating the anti virus. It is true that anti virus is created in such a way to guard your computers from the virus invasion. The anti virus companies update their software in a regular way. Please remember that the threats on the internet are really awful. You should never let your computer at home or everywhere are driven by Trojans, worms and even hacks.

While Macs are very good computers, there certainly is a premium to be paid for them. Is it worth the price? That really depends on the budget you have for a new computer.

Then again, a non-technical person that often has their computer infected with viruses, the cost of technician fees may make up the difference.
Another option available for you is to store some of your games directly to the Xbox. The Xbox hard drive is just a basic 2.5-inch SATA drive.

So It is really not recommended to backup lots of games on your Xbox 360 system.

The last resort is to reinstall your operating system, because you will lose all your saved files if you do this. However, this often resolves all your problems, especially if you have a particularly nasty computer virus that you just cannot get rid of.
