Is it a cold? No, it is a computer virus.

How many times did you yell at you computer because it behaved odd?
Now, how many times did you notice some new programs or toolbars or add-ons?
Well folks, it looks like you might have a virus. Your PC might be sick :(

                 In order to proceed with the story, let's define computer virus. Similar to any disease virus, computer virus is designed to spread all around from host to host, and even worse – it replicates itself. Be aware that computer virus can not reproduce and spread without an according programming in form of a file or a document. If you want a more techy explanation – than computer virus is a malicious code or a program written with the purpose to alter the way your computer works and is designed to spread from one computer to another.

History has recorded some serious viruses that really shook the entire world, so let me just give you an example of few:
  • ILOVEYOU: This virus was created by two Filipino programers. The attachement that was sent was named ILOVEYOU which made a lot of users to click on it. The Windwos would then become unbootable. It became so bad, that governments and corporations took their mailing system offline to prevent the further infection.
  • Code Red: Code Red was active in 2001 when the worm (virus) targeted computers with Microsoft IIS web server. Once infected, it would replicate itself in several hunderd of copies, but due to the bug in programming it even replicated more, which end up in „eating“ a lot of system recourses. After that it would launch a denial of service attack on several IP addresses  (White House was one of them). Total 1-2 million servers were affected causing $2 bilion cost of lost in productivity.
  • CryptoLocker: This virus used several methods for spreading, and once the PC would be infected, it would proceed to encrypt files on the hard drive. Even though it was easy to remove this virus from the computer, the files would remain crypted and the only way to unlock was topay a ransom by a deadline ($400 dollars). If you wouldn't pay by the deadline, the ransom would increase or the decryption keys would be deleted.

But, how did I get a computer virus?

Well, most efficient way is through e-mail, text messages, social networks and downloads. Next time you get an e-mail from sender that is not in your mailing list, think twice before opening the attachment. However, the sender can be somebody from your mailing list that you contact often, but you gotta ask yourself – „Why is he sending me an e-mail with this super-shady subject and an attachment that has some random generic name?“

I'm pretty sure all of us received some random Facebook message from a friend saying „I can't believe somebody posted a video of you: XXXXXXXXXXXX (link)“.
For the love of Internet, please don't click on that link. Even better, delete the message and warn your friend he has some suspicious behaving on his account.


Prevention

Well kids, the first rule of safe sex is: „Always use protection!“
The very same rule applies here – antivirus program! There are a lot of free ones that are really good like:
There are also ones for which you need some cash like (pretty sure all of the above can be paid too, like upgrading to the full and maximum protection):

At home, we use ESET NOD32, but I also tried AVG and Avast and all of them did a pretty good job (never had any serious troubles with viruses)!
 
                Most of these programs have a feature to run a check of your PC to find any hidden viruses and to clean them immediately – beware that might include deleting some of your files which are infected. If not even that is enough, you might wanna consider taking your PC to an authorized service provider to clean it or even to install new OS from scratch.

Oh, and next time your OS gives you a message to update - don't ignore it, because you're putting yourself at risk. Most of the OS update are security patches, that would protect your computer from the vicious attackers to use a bug or an oversight to launch their virus programs.

What are your thoughts on this topic - is your computer protected or are you living on the edge, walking freely without any protection? Love your computer - protect that little thingy!

(Sorry for I don't understand some words or phrases here!) Malicious code is created by computer programmer just for fun among themselves as what I have learned from a programmer friend. And business company has thought something that it could benefit from it. Thus, computer virus started to gain popular use and demand.

THanks a lot for this post. I am a bit careless in that field to be honest. Like I don't give much attention to make sure my laptop does not get infected. Now I'll be more cautious

Having a computer with an internet has become an integral part of every households and businesses, so protection is a must. I just couldn't understand why people have to create these viruses.

We are now more careful to download anything because of these pesky viruses. My sons used to download games left and right, but when the computer got bogged down because of viruses, they are now more careful and discriminate.

It's really important to update software. Virus can really be a problem. It's also good to avoid unusual links.

You should be more cautious, as the virus can also get to your blog site and take everything down. :/

To gain popularity perhaps? 5 minutes of fame? To access other people's data and bank information? Lots of different reasons :(

Parents that allow their children to use computer and Internet should think about "nanny" software. Such software has special permissions and setting so your kids can not go on non-verified sites or download just whatever they want to.
