A computer virus.

 It’s a computer program that can copy itself and infect a computer. The term “virus” is also commonly but erroneously used to refer to other types of malware, adware, and spyware programs that do not have reproductive ability.

A true virus can only spread from one computer to another (in some form of executable codes) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, OR USB drive.

Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer.

How to avoid Computer Viruses
  1. Don’t download anything from anyone you don’t know or aren’t expecting… EVER. For all you VAs, and publishers and whoever else out there is trading files back and forth with your clients… Stop and make sure that your client has a safe system before you start trading files with them. It’s worth the time.
  2. Turn off the autolaunch in your email client. I don’t even auto-launch graphics. Furthermore, READ YOUR EMAIL ONLINE! Don’t download the email until you’re 100% sure it is safe. 
  3. If your email has an attachment, go into your headers and look at it. If it’s got a pif or scr extension, chances are it’s a virus. If it’s any Microsoft program file, and you aren’t expecting it, it in itself probably isn’t a virus, but it could very easily have a virus embedded in it. The only things that hacker’s haven’t been able to embed viruses into, to my knowledge, are pictures. But just because it says it’s a picture doesn’t mean it is. Look at the attachment name. File names don’t lie. If it’s a .jpg.scr extension, it’s a virus.
  4. Antivirus protection programs are only ever as up to date as known viruses. They are also the first target of a virus, so don’t trust the antivirus protection program alone. If you’ve used your eyes and don’t believe it’s a virus, scan it anyway. I use Yahoo, because they keep Norton up to date and I don’t have to run it on my system. Norton in and of itself is a great antivirus protection program, but it’s not infallible.
  5. Set your computer so it doesn’t autolaunch files, updates, security checks, html pages, cookies, etc. without your permission!
  6. Get a quality anti-spyware program – They’re designed to get rid of programs on your system that send your data to the web and as such could be opening holes that you don’t know about.
  7. Set up a software firewall. If you don’t have a software firewall built in, upgrade your OS. And make sure everyone on your LAN is set up with the same firewall.
  8. Don’t rely only on the software; set up a hardware firewall. It’s called a router and it’s easy to set up and maintain.
  9. Take the time and make the effort to understand how viruses and worms get onto your computer and you can virtually stop them all in their tracks.
  10. Once you’ve got all your holes closed, get someone who knows what they’re doing to test it from the Internet side. If you don’t have someone, I can refer someone.
  11. Don’t let kids on the ‘Net on your system! I find it funny that businesses will spend billions of dollars on marketing and advertising, but they leave their computer systems open to hackers whose sole purpose in life is to take advantage of KNOWN cracks in the system. In my opinion, the only real hole is the User.
