Like with the human body, computer viruses are almost invisible when they first start attacking. By the time there are signs, significant damage has been done. Viruses can destroy computers, corruption and lost files and just overall privacy breach.
When dealing with a virus, you must know what kind you are dealing with. Different viruses have different solutions. Below are some of the types of viruses that you may encounter.
1. Direct Action Virus
This type of virus is the one that goes directly after the files in the hard drive and destroys them. They often include a line of code that will say that “All your computer files are being destroyed,” and in the end, if a computer gets infected with this virus, it will be rendered useless.
2. Boot Sector Virus
Boot Sector Virus is embedded in the disk’s master boot record. This refers to the hard drive’s boot sector, where the operating system is loaded. This virus is tough to detect and repair because when the infection is on your computer, the virus will not be recovered from the hard drive. The only way to get rid of this virus is to replace the hard drive.
3. Multipartite Virus
This virus can be found in files, boot sectors or disk sectors. This virus has two parts. One part stays in memory, and the other remains on the hard drive. This type of virus can be very destructive because it can spread quickly and multiply.
4. Resident Virus
This type of virus stays in the computer’s memory even if the system is turned off. This is the most destructive virus because it can survive from one computer to another and always be on standby.
5. Polymorphic Virus
This is one of the most dangerous viruses because it constantly changes its form. Because of this, antivirus programs will no longer detect and remove the virus.
6. Macro Virus
This type of virus replicates by attaching itself to existing files. The antivirus program will have to go through the entire hard drive and check for any infected files to remove the virus.
7. Browser Hijacker Virus
Some internet browsers are victims of viruses. This virus will change the computer’s browser settings to a different search engine and homepage. Usually, users will not notice this until they have had a browser hijacker for a long time, and the search engine you are using does not provide the results you want.
8. Web Scripting Virus
This is the one that will attach itself to web pages and directly infiltrate your web browser, possibly endangering any personal data. These viruses are more challenging to remove because they have ties to the server-side, and they invade your computer through the internet browser.
What to Do About Viruses
Since viruses are becoming more and more dangerous, it is essential to know what you can do about them.
Back-Up Your Data
The first step is always to back up your data. Viruses usually attack essential files, and by always having your files backed up, you will save yourself a lot of stress and a lot of time and money.
Be Careful When Installing Programs and Files
The second thing you can do is be more careful when installing programs and files. Many viruses come with infected files. If you are not careful, you could easily install a virus onto your computer.
Be Wary of Clicking on Links
Lastly, do not click on any links or download any files you are unsure of. This is the most common way that viruses are spread.
If you suspect that your computer has a virus, immediately call a professional. Many programmers are trained to deal with these issues and should help you.
Conclusion
Viruses are a real threat to computers. If you do not take precautions, your computer can get infected with a virus, and it can cause significant problems. Always back up your files and always be careful when installing programs. To learn more on how to protect your computer, contact a professional.
