What Is A Virus?
A computer virus is a malicious software program that designed to self-replicate by copying itself to another program without the user’s knowledge.

10 Most Common Types of Viruses Affecting Computers
Through the years, cybercriminals and even unwary programmers have intentionally and unintentionally created different computer viruses with varying impacts on systems across the globe. Here are some of the most common types that are affecting computers today.
Boot Sector Virus
This virus infects floppy disks and spreads through removable media. It often requires you to reformat the drive to get rid of the virus.
Direct Action Virus
This non-resident virus stays hidden in the computer memory infecting .exe and .com files. There’s no effect on user experience and system’s performance, but it affects files and folders that it’s in.
This virus alters its signature whenever it replicates, making it difficult to identify with signature searches.
This virus gets installed on the computer and lives in the RAM. It interferes with the system’s operation and corrupts files.
This virus overwrites the content of the file causing you to lose the original content. You will also have to delete the file to get rid of the virus.
This virus lives in executable programs and once you run these programs, the virus gets activated causing your computer to slow down.
This virus appears like a normal file or a program. It can temporarily remove itself from the program, so some antivirus software can’t detect it.
This virus uses codes making them hard to detect and the only way to track them is during replication and decryption. Encrypted viruses badly affect PC performance.
This virus brings you to different infected websites infecting your web browser. Most trusted browsers have tools to block these types of viruses.
Web Scripting Virus
This virus carries malicious codes and directs you to malicious websites.
Top 10 Most Popular/ Dangerous/ Widespread Computer Viruses
Some of the most dangerous and widespread computer viruses were not intentionally made to cause harm. However, their rapid spread caused panic among companies, resulting in operational disruption that valued millions of dollars spent to control them.
The ILOVEYOU virus affected almost 10% of the world’s computers, forcing the government and big corporations to pause their mailing system to prevent infection. The creators of the ILOVEYOU virus, two Filipino programmers by the name of Reonel Ramones and Onel de Guzman, used social engineering, a case of love confession to trick people into clicking on an email attachment. Once a user clicks on the TXT file, which is a script, it can send the script to the user’s mailing list.
#2 CODE RED
They named code Red as two digital security employees were drinking Code Red Mountain Dew when they discovered the virus. The worm runs on memory and has only 3,569 bytes, leaving very little trace but can double itself with a bug in the programming. It affected a whopping two million servers out of six million ISS servers.
Cryptolocker is a Trojan horse ransomware that spreads itself in different ways and encrypts files on the hard drive. People who paid to get their files decrypted amounted to three million. Eventually, they charged the creator Evgeniy Bogachec and made him release the encryption keys that affected the computers.
The Israel Defense Force worked together with the American government to create Stuxnet, a virus for cyber warfare that they created to disrupt Iranians’ nuclear efforts. They have successfully done so, ruining one-fifth of Iranian centrifuges.
#5 SASSER AND NETSKY
Sasser and Netsky were created by computer science student named Sven Jaschan. These viruses took advantage of a buffer overflow in the Local Security Authority Subsystem Service on Windows, leading to millions of computer infections that affected airlines, news agencies, hospitals, public transport, etc.
#6 STORM WORM
The Storm worm posed as a news-containing email with a subject line “230 dead as storm batters Europe.” Again, intrigued by the news, people will click on the email and once they do, they will receive a huge amount of spam emails.
#7 THE MORRIS WORM
Robert Morris, who at the time was a graduate student at Cornell, created the first worm that distributes via the Internet. He was also the first to get sued under the Computer Fraud and Abuse Act.
MyDoom has been the fastest spreading virus next to ILOVEYOU. The creator is unknown and with a message containing, “andy; I’m just doing my job, nothing personal, sorry” seems like the creator was just paid to do it. Aside from spreading itself to the user’s mailing list who clicks on the email like ILOVEYOU, it also opens a backdoor for remote access. A McAfee employee discovered it with a line in the code containing ‘mydom’ in the script. Predicting that it would be big, they later named the virus as ‘mydoom.’
#9 ANNA KOURNIKOVA
The tennis player Anna Kournikova had nothing to do with the creation of this virus, but tennis sports and Kournikova were such a big hit and were the most searched term on the Internet. Jan De Wit, a 20-year-old Dutch, took advantage of this and created a virus joke. People click on anything that relates to the name. He eventually turned himself in. The town’s mayor though had a different plan for him in mind, offering him a job as a techie after he graduates.
The WannaCry virus only lasted for days but spread across 200 to 300 thousand computers worldwide. It uses backdoor exploitation to spread to computers, and then hold files for ransom.
Things To Consider When Choosing Antivirus Software
Whether you’re a typical consumer or an IT professional who’s managing a company’s IT network, you must take into account some pointers when buying an antivirus software solution. Here are some factors to consider before making a decision and shelling out that hard-earned money.
It’s not enough that you find antivirus software that performs scheduled scans to look for unsafe programs you might have downloaded and installed on your PC. What you should look for is the one that prompts that you might be vulnerable to some threats.
Some antivirus software solutions aren’t compatible with every operating system that you are probably using. Best to check the compatibility of the software with your device before you decide to buy one.
A virtual private network (VPN) uses encryption to hide you from cybercriminals when you are connecting to and browsing the Internet. What a VPN does is mask your identity and location to make you safe from any threats.
DNS hijacking directs you to an inauthentic website when you visit an authentic one. You should also look for DNS protection so you know you’re safe from sharing your info in an almost similar website that you thought was the real one.
Camfecting is widespread, and it’s been a persistent problem as these are attacks that don’t invade your bank info but your privacy, taking whatever footage they like for their amusement.
Anti-phishing software has programs that identify phishing content in websites, emails. Having this feature gives you a warning when you are about to give out information from phishing.
When you encounter some issues with the software, you will want to call for support from the solution company. Some software solutions won’t offer this and you are better off finding a product with additional help.
It’s also worth weighing the prices offered as some will be cheaper than others but will require additional bucks to maintain or to have as many features as you needed.
