Computer viruses are nothing to sneeze at. They can range from somewhat annoying to extremely destructive. A virus can arrive into a computer’s system as easily as slipping in through an email attachment.
It can also be loaded through software and downloads from the Internet. Like the biological virus, it is easily passed from one computer to another and can lead to an epidemic.
Imagine now that some person, a hacker, is trying to get your personal information; your social security number, your phone number, address, even a computer copy of your signature. They could use it to go shopping, but it is doubtful. He or she may be getting it to sell it to someone else so they can use it. Any information that is in cyberspace can be tampered with or collected.
There are many different types of viruses that can affect computers and each is different in the damage it may cause. For example, a resident virus can do damage such as corrupt files and programs on the computer, whether or not the applications are open or closed. It dwells in the RAM or random access memory.
Basically, a computer virus is a software program that spreads from one computer to another. This causes interruptions in the computer’s systems. It can corrupt or delete information stored on the computer. Some use email to transfer viruses from one computer to another.
The scary part of this is that a government computer was affected as well. If cyber-terrorists want to get control of a country’s communication, transportation, electricity, water power and any other important industry, it is not completely out of the question.
Symptoms of a computer virus are slowing down of the actions you are performing, locks up frequently or freezes up while working on it, crashes and restarts on its own, and you may receive strange error messages. Those are only a few of the signs that point to a viral invasion. It is important to keep antivirus software running on your computer to protect it from most hazards.
Luckily, there are also people that spend much of their time combating these viruses as they are spread or about to be spread. Hopefully, they will triumph and put an end to the evil viruses.
