Don’t get so nervous about viruses! While it’s true they are out there, they are not as omnipotent as you might think. A little prevention can go a long way.
One virus you might encounter is an executable virus. These live in the .exe files that we often click on without thinking twice. They are actually extensions of the executable files, and the virus loads itself into the memory and puts copies of itself into other executable files, thereby proliferating.
Another common virus is a Trojan virus. These are independent programs that disguise themselves as a program you might actually want to run.
You have probably also heard of worm viruses. These do not reproduce throughout your computer, but instead take advantage of a network connection to spread the virus to other computers.
Using an antivirus program on your PC will help keep you safe, as the program will scan your computer for viruses periodically. Human effort can also keep viruses out of your computer. Don’t download attachments if you don’t know where they come from, and know where your software comes from before you install it on your computer!
