Since the advent of the internet, there have been hundreds of types of computer viruses, each with different functions and purposes.
Some viruses spy on data, files, passwords, and everything typed on the computer's keyboard.
There are also other types of viruses that infiltrate DLL files to gain control over all computer services such as the keyboard, mouse, printer, camera, microphone, and even transfer or delete files! All of this happens without the user's knowledge.
In the following sections, the Tech Gena team will detail the three most dangerous and well-known types of computer viruses, the potential damages that may occur upon infection, and how to combat them:
1: Keyloggers
Keyloggers are viruses programmed to monitor everything typed on the keyboard, spying on personal communications, passwords, banking information, and sensitive work data!
Initially, the virus is embedded in a file, program, or game and sent to the target, known in cybersecurity as the "victim" — the owner of the compromised computer.
After deceiving the victim with a malicious program disguised as a game, application, or any file, everything typed on the keyboard is then monitored by the hacker who designed this virus!
2: Trojans
The Trojan virus ranks as the most widely spread virus globally and has a notorious reputation!
The hacker combines the virus with an image, game, program, or even a video file or song, then sends it to the target like bait for them to click on!
Once the victim's computer is compromised, the hacker can control all of the device's services to an extent unimaginable to anyone! The hacker will have more control than the computer's owner themselves!
Therefore, we highly recommend using the best free antivirus software such as Kaspersky, Norton, Avira, Avast, or ESET Antivirus.
3: Ransomware
Ransomware has emerged recently, targeting companies, government institutions, and high-profile individuals within countries, such as heads of state and business leaders.
This virus encrypts all files and halts all services entirely, then displays a pop-up window on all company devices stating, "To decrypt your files, pay the ransom now."
This virus is considered one of the most dangerous and aggressive types of viruses that are difficult to treat after infection, not before! You can protect yourself beforehand by installing one of thereputable paid antivirus programs.
However, if you have already been infected with this virus, recovering files becomes challenging and will likely require the assistance of experienced technical experts.
Unfortunately, there is only a 60% chance of successfully recovering files, and even then, not all files may be restored!
Scientifically Correct Treatment for Computer Viruses
- After installing Windows, immediately install an antivirus program!
- Do not click on any suspicious links sent to you via email.
- Ensure that the Windows Firewall is activated.
- Be cautious of adult sites and suspicious websites, as they may contain dangerous viruses.
- Avoid clicking on advertisement images on questionable websites.
- Use VPN programs to change your IP address to enhance your computer's security.
