The term "computer virus" is sometimes used as a catch-all phrase to include all
types of malware, adware, and spyware programs that do not have the reproductive
ability. Malware includes computer viruses, worms, trojans, most rootkits, spyware,
dishonest adware, crimeware, and other malicious and unwanted software, including
true viruses. Viruses are sometimes confused with computer worms and Trojan horses,
which are technically different. A worm can exploit security vulnerabilities to spread
itself automatically to other computers through networks, while a Trojan is a program
that appears harmless but hides malicious functions. Worms and Trojans, like viruses,
may harm a system's data or performance. Some viruses and other malware have symptoms
noticeable to the computer user, but many are surreptitious and go unnoticed.
Viruses are executable files that once activated are able to do catastrophic damage
to your computer. They can often be found in email messages with attachments that
are inadvertently opened as they appear to be genuine, instant messaging, files/programs
downloaded from the internet or by pirated infected software.
Some signs that your computer may be infected are:-
- The computer runs slower than usual.
- The computer stops responding, or it locks up frequently.
- The computer crashes, and then it restarts every few minutes.
- The computer restarts on its own and the computer does not run as usual.
- Applications on the computer do not work correctly.
- Disks or disk drives are inaccessible.
- You cannot print items correctly.
- You see unusual error messages.
- You see distorted menus and dialog boxes.
- An antivirus program cannot be installed or the antivirus program cannot run
- A program disappears even though you did not intentionally remove it.
- You may get constant pop-ups advertising various products, including pornographic
websites.
Once a virus has infected your computer how it got there is not as important as how
to get rid of it and prevent further infection. Prevention is always better than
a cure, but if you do suspect you have a computer virus it is vital that you ACT
FAST to prevent further infection and damage to your computer. Once a computer has
been compromised by a virus, it is usually unsafe to continue using the same computer
without completely reinstalling the operating system. However, there are a number
of recovery options that exist after a computer has a virus. These actions depend
on severity of the type of virus.
