There are quite a few ways for Computer viruses, worms, & Trojan horses to deliver their payload or instructions. The main one is from downloading things form the internet, so if you download a lot of things you should always scan the files before installing or opening them, especially executable files (do not download from dubious sources).
Running infected programs, which is the second common way for network attacks to act usually happens when one does not check the file or program with computer security program. One of the most commonly heard of way how people have their computers attacked by computer virus, worm, or Trojan horse is by email attachment. Another is from infected files transported by flash drives from one computer to another.
