In today’s digital world, computers are key to our daily lives. They help us manage money and stay in touch with loved ones. But, they also face threats like computer viruses.
Computer viruses are harmful programs that can damage or steal from your computer. They can sneak in through downloads, links, or email attachments. Once inside, they can harm your data, steal information, or even make your computer unusable.
Knowing about different viruses is important to keep your computer safe. By understanding these threats, you can protect your device and know how to fix it if it gets infected. This article will cover five common viruses, their effects, and how to prevent and remove them.
5 Types Of Computer Viruses You Need To Know
1. Trojan
Trojan viruses are very dangerous and often trick users into installing them. They pretend to be safe software to get downloaded. This makes them very dangerous because they need your help to spread.
Once a Trojan gets into your system, it can steal your personal info without you knowing. It can also let hackers control your computer. They might use it for other cybercrimes or turn it into a botnet.
To avoid Trojans, stay safe online. Don’t download from unknown sources, be careful with emails, and avoid suspicious links. Using antivirus software, like Trojan Remover, can also help protect your computer.
If you think your computer has a Trojan, act fast. Use your antivirus to scan and remove it. Also, change your passwords and watch your accounts for any odd activity.
2. Worm
Worms are viruses that can spread on their own. They find weaknesses in systems to move from one computer to another. This makes them good at spreading fast.
Worms might not be as harmful as some malware, but they can slow down your computer. They can also use up a lot of resources, leading to crashes. Some worms can even bring in more dangerous malware.
To stop worms, keep your system and software updated. Use security patches to close vulnerabilities. Also, install a strong antivirus program, like Avast or Bitdefender, to catch and block worms.
If you get a worm, act quickly. Turn off your internet to stop it from spreading. Use your antivirus to scan and remove it. Then, update all your software to avoid getting infected again.
3. FAT Virus
The File Allocation Table (FAT) virus is a sneaky malware that targets older Windows versions. It corrupts and deletes files on infected devices. This makes it a big threat to your data and computer.
When a computer gets infected with a FAT virus, it can hide or delete files. Losing important documents or photos can be very bad. Unlike some viruses, the FAT virus directly attacks your files, leading to permanent loss if not fixed fast.
To avoid a FAT virus, you need to be careful and use good antivirus software. Tools like Malwarebytes, Norton AntiVirus, or Kaspersky Anti-Virus can catch and remove the virus. Also, don’t use old software or operating systems to lower your risk.
If you think your computer has a FAT virus, act fast. Run a full scan with your antivirus to find and remove the virus. If you have backups, use them to get back lost data. Always keep backups and update your system to prevent future problems.
4. Memory Resident Virus
Memory Resident Viruses live in your computer’s RAM, staying active all the time. They slow down your computer by using a lot of memory. This can make your computer slow and crash a lot.
Unlike other viruses, Memory Resident Viruses work all the time. They can mess with your computer, making apps not work right. They are hard to find and remove, needing special tools and scans.
To fight Memory Resident Viruses, use strong antivirus software like Malwarebytes or Avast. Keep your antivirus up to date to protect against new threats. This helps keep your computer safe.
If your computer starts acting weird or gets slow, it might have a Memory Resident Virus. A deep scan with your antivirus can find and remove it. Also, keep your system and drivers updated to stop viruses from getting in.
5. Multipartite Virus
Multipartite Viruses are very dangerous because they can attack your computer in many ways. They can harm your operating system and executable files. This makes them hard to get rid of.
A Multipartite Virus can really mess up your computer by damaging important files. This can make your computer slow, have errors, or even stop working. Because they can spread in many ways, removing them can be tough.
To stop Multipartite Viruses, keep your computer and software up to date. Use good antivirus and scan regularly. Also, be careful with what you download and avoid bad websites.
If you think your computer has a Multipartite Virus, act quickly. A full scan with your antivirus can find and remove it. Sometimes, you might need to restore from a backup or reinstall your system to get rid of it completely.
Preventing and Removing Computer Viruses
To keep your computer safe from viruses, you need a solid plan. Here are key steps to protect your device:
- Install Reliable Antivirus Software: Pick trusted antivirus programs like McAfee, Malwarebytes, Norton, or Kaspersky. They guard against malware, including Trojans and worms. Make sure to update them often to fight new threats.
