If humans suffer from viruses, computers also have their own version of computer viruses. This is the reason why computers that are sold have preinstalled antivirus programs. Experts view computer viruses as real threats and you will lose thousands of important data if you underestimate these threats. For those that don’t know the effect of viruses to our computers, here are some concrete examples.
You might be surprised because your computer has hung up or is slowing down. Your computer can usually run any program but all of a sudden will hang up when you try to run one program. This may be caused by a computer virus. The computer virus will usually run an illegal program in the background and takes up the computer memory. This is the one that causes the computer to hang. This will create a problem especially if you have some urgent tasks to finish. You must remove viruses so you will not encounter lags.
There are also viruses that turn your files into a different file extension. For example, if you have a word file that was saved in a .doc format. When the virus attacks, all your .doc files will be changed to .exe files. These are one of the common effects of viruses and will become a burden to those who are not familiar with viruses. In reality, the virus hides the right files and creates a .exe file using the filename of your original files. You should know these effects so you’ll not underestimate computer viruses.
