Safety on the Internet: To click or not to click
Every day the “bad guys” come up with more ways to prey on our computers.
They develop new viruses and new programs that at worst, steal our personal information, and, at best, slow our computers down.
Both PCs and Macs are victims to malware; it’s a myth that Macs are immune.
Here are some tools you need to keep your computer safe while you use the Internet.
The first step is to make sure we are all speaking the same language, so here are some definitions of all the bad stuff that’s out there in the cyberworld.
– Malware: This is a general term which includes any type of virus or malicious software. Any program whose purpose is harmful in any way is a malware program.
– Virus: A virus is malicious code that can spread to new disks or programs.
– Spyware: Spyware can monitor your computer tasks and steal your passwords and other information.
– Adware: Adware pops up unwanted advertisements. Sometimes these ads target your interests by using information stolen by a spyware program.
– Dropper: Some malicious programs can be tiny programs specifically designed to funnel a stream of other malware into your computer.
– Bots: A bot doesn’t usually harm your computer, but it makes your computer a robot to harm others by sending malicious programs or spam to your email address list.
– Ransomware: Holds your computer or data ransom and demands payment before it will release it. Of course, there is no guarantee that paying the money will get your data back since the program is designed by unscrupulous people.
– Rootkit: This technology attaches to the operating system to hide the malicious program. Sometimes your anti-virus program may remove parts of it, but as you reboot your computer the virus comes back.
– Scareware: Some free “anti-virus programs” you may download from the Internet may actually be rogue viruses that will look and act like real Anti-Virus programs. They may diagnose a myriad of “problems” on your computer. These programs will then try to scare you into buying their “full version” so you can “clean up” your computer and “remove viruses.” Sometimes Scareware will run when your computer starts and it doesn’t offer a way for you to stop them.
– Junkware: Last, but not least, we have what we call “Junkware.” These are programs that we see over and over again in the shop. They may not actually be malicious, but they are programed to start every time you turn on your computer and usually are not anything you want running. A lot of anti-virus programs will not catch these because they are not considered viruses. The majority of these programs come packaged with other useful free programs from the Internet.
In an upcoming article I will explore anti-virus programs and tell you how you can protect your computer for free.
