Protect yourself

I’ve just spent the last few days at work fighting a nasty virus…several days and some long hours.  I thought I throw this post out there to help anyone who might be listening.  So what exactly is a virus?  Well that term is often used loosly to describe several different types of computer threats.

A virus is a computer program that attaches its self to another program or file allowing it to spread from computer to computer causing varying degrees of damage.  They ususally sit dormant until activated by someone.

A worm is similar to a virus, but can travel without your help….there’s no need to double click it to get it going…it goes all by itsself.  Some worms have been known to replicate themselves by contacting everyone in the users address book…and sending a copy of itsself.

A Trojan Horse is just like it sounds….its a program that caims to do one thing, but does something else.  I have seen some programs that claim to be virus removal software, but are actually programs that just open your system to more attacks from other nasties.

Spyware is software that usually does no harm to your system, but just tracks your actions…and sends that info to others.  This is where we get a lot of those anoying pop-ups, and this usually makes our computers run slower.

So how do you protect yourself?  It’s impossible to be 100% protected from everything that comes along, but there are a few steps you can take to eliminate a vast majority of existing threats.

1.  Don’t open attachments.  Never open an attachment unless you know what it is ahead of time.  Even emails from your friends can contain malware, and no you will not die if you don’t forward it to 10 others.

2.  Keep your operating system up to date.  If you’re a windows user, you can do this through Internet Explorer.  Those who create viruses look for vunerabilities in operating systems, and when found write harmful programs that take advantage of those loopholes.

3.  Keep your anti-virus up to date.  I’ve had a lot of people ask me which anti-virus is the best.  Honestly,  I think there all pretty good.  Trend Micro, Symantec, McAfee and AVG do a nice job of keeping computers clean.  To be quite honest….if you don’t want to use an anti-virus, then why spend your money on a computer?  It’s like driving your car without insurance….actually a bit worse.  If you don’t use an antivirus, and you connect your computer to the internet, you will become infected……
