Hence, computer users need to understand the most common computer security threats and take appropriate measures to protect themselves. Here are some of the most common computer security threats and what they can mean for you.

Ransomware is one of the most dangerous threats out there. The word “ransom” means “give up.” Hence, a hacker sends a message demanding that you give him sensitive data if he does not destroy his rival’s computer. Thus, the most common computer security threats become even more sophisticated as time goes by. Indeed, all people play a crucial part in securing their information.

Identity Theft

Identity theft is perhaps the most common and the most dangerous among all computer security threats today. This is because identity theft involves false claims made to your creditors about your financial status. It is a crime of deception. As soon as your identity is stolen, all your personal belongings and other properties are used to settle the score with your creditor. From thereon, your identity is misused to pay bills and buy expensive items that you did not have access to before.

Viruses and malware are also very common as well. Some of the most harmful cyber threats include worms, Trojans, spyware and adware. Worms are usually sent via emails, where they infect your computer through a download. Trojans are installed on the infected computer and allows hackers to access and utilize your system resources. Spyware is installed on your PC without your knowledge and once installed, monitors all actions taken on your system.

Viruses Are Spread Through Programs

Other malicious codes like viruses are spread through programs. The most common viruses are viruses, worms, Trojan horses and even spyware. The latter are spread through files, websites and email attachments. You will never know that you have been infected until your PC crashes or you start to suffer from strange symptoms. Unlike worms and viruses, malware does not harm your computer. They only give you trouble by slowing down your system, forcing you to constantly reboot or track down your CDs or DVDs and blocking your programs from running.

Phishing is yet another type of computer security threats wherein hackers use fake security certificates to obtain your passwords and personal data. Most phishing attempts are done via email, since most people check their emails. Most phishing attacks happen when a scam artist crafts an email asking for your bank account numbers, passwords or any other information that can grant him access to your finances. Most victims are unaware that they have been victimized until they receive phone calls or messages from someone claiming to be a bank or asking them to click on a link in an attempt to get their passwords. Once this happens, your bank account details have been stolen and your privacy has been compromised.

Phishing Scams Are Email Campaigns

Other common computer security threats include phishing scams and identity theft. Phishing scams are email campaigns that look very professional, resembling legitimate emails from your bank or credit card company.

In reality, however, they are sent out by hackers who obtain your personal information so they can steal your financial information. Cyber-security firms have developed security software that can detect these types of phishing attacks and block them.


Identity theft, on the other hand, is a malicious attack whereby hackers take advantage of your personal information and use it for their own personal gain. This most common computer security threat is done through Internet scams. Hackers gain access to your private information by posing as a legitimate business such as PayPal or your bank. Once they have obtained this information, they use it to access your bank account and transfer funds to another location. These types of attacks are extremely damaging and they can cost you a great deal of money to restore your financial standing.
