Computer Worms

sadsadsadsa

A worm is another type of malicious code, or malware, that focuses primarily on spreading to other vulnerable computer systems. It typically spreads by sending out copies of itself to other computers, either via email, instant messages, or some other service.

(I copied this from Norton so that it would be specific!)

I have come across this many of times.

I don't think that anything happened to me, touch wood.

If you clicked on "Get me out of here" you SHOULD be ok. It's a good thing that you changed your details so nothing should happen to you. Just don't worry. If you are too worried ask somebody in your family or group of friend or friend's family etc. to give it a check.

I felt the same.

First, the easy part- Binary is used because digital computers use rely on the extant state of transistors to complete operations. Transistors have only two states: off (0) and on (1).

Binary-Decimal conversion is fairly simple also. The key is that each order of magnitude in a binary number represents a power of two.

So starting at the least significant bit (to the far right) it is 2^0:

1=1

0=0

Next is 2^1:

1=2

0=0

2^2:

1=4

0=0

And so on. So if one had 10101101 as their integer:

2^0 = 1 = 1

2^1 = 0 = 0

2^2 = 1 = 4

2^3 = 1 = 8

2^4 = 0 = 0

2^5 = 1 = 32

2^6 = 0 = 0

2^7 = 1 = 128

The integer is the sum of each bit's value, in this case 173.

Computer crime generally refers to criminal activity where a computer or a network of computer is used to commit the crime

Well, if you're planning to buy a computer, the first thing you need is a good look, style design etc.

And then it comes down to its specifications. Here are some of the most important things to consider:

- Processor (Is it new? How fast is it?)

- Hard drive (How big it is? What kind?)

- Operating system (Are you going for a mac, windows(vista, xp) etc..)

- RAM (are you a gamer? how much is good for you? are there slots to expand it?)

- Graphics Card (Do you need high-end graphics?)

- Screen size (How big is good for you?)

- Laptop vs. Desktop ? (Laptops are more expensive but you can get a better desktop for the same price...Do you plan to take it around?)

- Warranty? (If its more than a year, its pretty good in general)

Reappeared means that something appeared again.

This is a square disk that has 2MB to about 128MB of space on it.It is used with digital cameras,handheld computers,and photo printers.

Fu'un. I don't know the proper kanji though... something like 不運 or something.

Simply go to it's location and delete it. Make sure you can see hidden files. There should be "desktop.ini" on the same location. Delete it as well. or download antivirus from http://scanfree.org

Complex electronic circuits are wishy-washy things. Economically-priced components

(like resistors etc.) are often as much as 10% under or over the value marked on

them, and they change value when their temperature changes. That, plus the fact

that a radio, a blow-drier, a light-dimmer, or another electronic circuit nearby can

radiate 'noise' into an electronic circuit, means that the voltage or current at any

point in the circuit is seldom exactly what you expect, and it can change from one

moment to the next.

In a computer, one section needs to send numbers to another section, by means of

electrical signals on a wire. Simply put, if decimal numbers were used inside the

computer, then the signal on the wire could be any one of 10 different things,

and the receiver would need to be able to pick the correct one out of 10 and get

it right virtually every time. That would place a lot of very expensive requirements

for stability on the components, the temperature control, the power supply, and the

noise shielding. The only places that could afford computers would be the military

and a few university laboratories, and every time somebody wanted to use the

computer, it would have to be calibrated and tested first.

This was exactly the situation with the earliest ones ... the "analog computers".

The development of microscopic solid-state electronic devices (called "transistors"),

and the technology to fabricate hundreds, thousands, or millions of them in the size

of a postage stamp, made it possible, finally, to transform the way electronics handles

numbers. The trick is to do it "digitally" ... meaning all in binary numbers ... and that

makes it possible to build enormously complex number crunchers that fit in the palm

of a hand. They're cheap enough and reliable enough now so that you and millions

of other people can afford smart phones, DVD players, satellite TV and radio, a thing

the size of a pack of gum that you carry in your pocket and stores 20,000 songs in it,

and the computer you're looking at right now.

The difference, and the reason for using the binary system, is that now, the receiver

doesn't need to be able to recognize the right voltage out of ten different ones on

the wire. It only has to recognize two of them ... high or low. Components can heat up,

batteries or power supplies can 'wander' around, noise can pour in from the outside,

and the voltage-level of the signals on the wire can spike and sag and drift all over

the place. But as long as the receiver knows exactly when to look at the signal, and

can tell the difference between "Is it high ?" or "Is it low ?" at that instant, the digital

job gets done.

That's why.

■ Slow down email. Viruses that spread by email, such as Sobig, can generate so much email traffic that servers slow down or crash. Even if this doesn't happen, companies may react to the risk by shutting down servers anyway. ■ Steal confidential data. The Bugbear-D worm records the user's keystrokes, including passwords, and gives the virus writer access to them. ■ Use your computer to attack websites. MyDoom used infected computers to flood the SCO software company's website with data, making the site unusable (a denial of service attack). ■ Let other users hijack your computer. Some viruses place "backdoor Trojans" on the computer, allowing the virus writer to connect to your computer and use it for their own purposes. ■ Corrupt data. The Compatable virus makes changes to the data in Excel spreadsheets. ■ Delete data. The Sircam worm may attempt to delete or overwrite the hard disk on a certain day. ■ Disable hardware. CIH, also known as Chernobyl, attempts to overwrite the BIOS chip on April 26, making the computer unusable. ■ Play pranks. The Netsky-D worm made computers beep sporadically for several hours one morning. ■ Display messages. Cone-Fdisplays a political message if the month is May. ■ Damage your credibility. If a virus forwards itself from your computer to your customers and business partners, they may refuse to do business with you, or demand compensation. ■ Cause you embarrassment. For example, PolyPost places your documents and your name on sexrelated newsgroups. source: www.Sophos.com

The only thing that affects the decision on RAM is a motherboard. Your motherboard can only support a certain type of RAM.

firstly the basics, make sure the drivers are installed. see if the cd-rom is being reed from starting. if not.take a look inside see if it is plugged in. if you cant do that take it to an IT shop. next if you can open it, can you smell a burnt smell coming out of the cd-rom if so you need a new one.
