Cyber Security in an Online World

You may use the internet all the time but do you really know what protects you against viruses, malware and malicious software? Some people devote their lives to create deadly software that can actually deem a machine unusable.

At the bottom of this article, there are some links to official software for your protection.

What Is A Virus?

Computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation. A virus might corrupt or delete data on your computer, use your e-mail program to spread itself to other computers, or even erase everything on your hard disk.

There are protection methods, however, like AVG and Norton security that block malicious connections from the dark web (not accessible via any search engine or many web browsers) that spy on you collecting every keystroke1. These keystrokes can be passwords, bank details, online shopping or even those embarrassing pictures hidden in that folder in documents.

Unfortunately, these types of spyware are just the beginning, Ransomware is another big problem for it encrypts all the data except the boot files and makes you pay a sum of money, iusually n a Cryptocurrency2 before your files are decrypted. It’s ok if your files are decrypted but if you leave it more than a specified time limit, the unlock key is destroyed and your data is lost forever. This would, in turn, destroy all removable media and network drives attached to your computer(s) at the time.

Beware though as sometimes you can download innocent-looking protection software for your computer but it then plants itself into many places so opening a file would ask for money, shutting down the computer would ask for money and it would be very hard to remove. These are called Trojans, sometimes referred to as Trojan Horses and most anti-virus with a live scanner can stop these from even executing their tasks.


You can get free security trials from AVG and Norton that protect you from most types of malicious software. Remember on Norton to find a version with Firewall3 protection.
