As many peoples “Computer Guy” I get to see a lot of PCs in very bad shape. Most of them are totally filled with Malware. Here is Wikipedia’s definition of Malware:
Malware is software designed to infiltrate or damage a computer system without the owner’s informed consent. It is a portmanteau of the words “malicious” and “software”. The expression is a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software or program code.
In other words; it is stuff on your computer that you don’t want and that can make your life miserable.
I am often amazed in these times how many computers I sit down to that have absolutely NO protection from the poo-poo that you can get from the internet. I try not to lecture people about going to websites that are bad or downloading whatever, but if you’re going to play in the places that can do your computer harm PLEASE take something to protect you.
Many, many people will say they have virus protection, but I’ll look and see that their subscription ran out a year ago. Let me explain how an antivirus application works:
1.A bad guy writes a program that is harmful to your computer.
2.They release it to the world, usually through the internet or e-mail.
3.Somebody gets the virus on their computer (usually several people).
4.The virus gets reported to the people who write the antivirus software.
5.The Antivirus software people write code for their product that looks for and protects you from this virus.
6.The Antivirus people put their code up on their server for you to download.
7.Your machine downloads the code from the server.
8.Your computer is protected from the Malware.
Understand that the time between steps 6 and 7 can sometimes be a whole week. The time between steps 2 and 3 can be a lot longer. So until you actually get to step 8 you are NOT protected. And if you are not currently getting updates for your antivirus program you will never make it to step 7. You must realize that there is a period of time with any virus that you are not protected, and if you do not have an updated program you are NEVER protected.
Scared? Good!
So what should you do about it? The best defense is safe computing practices, but I’ll save that for another post. Mainly, get an antivirus program. Secondly, make sure it is getting updates regularly. I cannot recommend one program over another because they are constantly changing. One week one is better and the next week another one is better. Of the ones I have used and feel confident with are (in no particular order):
Symantec (Norton) (www.symantec.com)
McAfee (www.mcafee.com)
Panda (www.pandasecurity.com)
Tend Micro (www.trendmicro.com)
AVG (www.grisoft.com)
There are probably others, but like I say – these are the ones I personally have had good experiences with. Another one that I have heard a lot of good things about is NOD32 (www.eset.com), but I haven’t had a chance to use this yet.
If you are trying to find one that works for you shop around. See what prices work for you, and most of them will allow you a trial period. If you download a trial remember two very important things: 1) When the trial runs out you must pay for a subscription to continue to get updates 2) If you install a different antivirus program be sure to uninstall the old one first. It’s a good rule to never have more than one antivirus program installed on one computer.
If you are squirming about paying for software you don’t want to have to buy check out AVG. They have a free version. There does not seem to be any catch to this and I have installed it on many machines. It is a basic antivirus application. It scans files as you access them, scan e-mails and does a complete scan every day. One thing I really like about this program is it updates every day instead of once a week.
Other tools that can help remove malware from your machine are AdAware (www.lavasoftusa.com) and SpyBot (www.spybot.info). Spybot is totally free and AdAware has a free version for personal use. Both of these programs will scan your system for potentially harmful or annoying programs. You will have to update and run these manually. In other words just installing them on your machine does absolutely nothing. You have to run the application, get the latest updates, run the scan and remove the problems.
IMPORTANT! I only recommend these two programs, and you MUST get them from the websites above. There are other applications that have the same or similar names. Most of these are phonies and actually install malware on your machine. Do NOT install a spyware program that you find on the internet unless you are ABSOLUTLY sure of what it is and what it will do. You are doing more harm than good by installing unknown spyware, antivirus, malware, registry cleaner or whatever. Just because it says it is going to fix your problems does not mean it will. Have I made this clear? I don’t know what else to say about this….
Another application that has to be mentioned is Windows Defender (http://www.microsoft.com/athome/security/spyware/software/default.mspx). This is Microsoft’s antispyware application. It is free. I do believe it is good and worth installing, but it’s one of those applications like Malicious Software Removal Tool that seems to be working, but I can never verify that it is or it’s not. The price is right, but I wouldn’t rely on this solely.
So, you are probably reading this because I sent you to it. Right now look at your machine and see if you have any antivirus program running. If you do check that the definitions are up to date – no more that 7 days old. If you need to update, do so. If you need to renew your subscriptions, do so. If you don’t know what to do, then call a computer guy to help you. I’ll be glad to help if you are in my area. If you are somewhere else then I’m sure you can find a geek out there that will help you out.
Just be safe!
