What is Computer Viruses and How to Avoid Them – Best Information

What is Computer Viruses and How to Avoid ThemComputer viruses can infect any computer and cause serious damage. The best way to protect your antivirus from viruses is to install an updated antivirus program. There are many types of computer viruses prevalent around the web and computers. Computer viruses spread over a network by infecting network file systems or file systems that are accessed by another computer.

Types of Computer Viruses

Simple Virus – Simple virus targets the program file and when you run that program it gets executed itself. This virus automatically attaches itself to other programs.

Encrypted Virus – Antivirus software can easily track most of the viruses on the computer. An encrypted virus is a virus that cannot be trapped by antivirus software because of its encrypted code.

Polymorphic Virus – The evolution of polymorphic viruses infects the virus’s sign, making it more difficult for antiviruses to detect the virus. Polymorphic viruses can only be detected by special codes written specifically for polymorphic viruses.

Macro Virus – Macro virus as its name suggests is a mini-program that runs inside other programs. Basically, macro viruses are scripts that are written specifically to infect computers. They can spread quickly as they infect popular applications used in daily computing activities.

Trojan Horse – A Trojan horse is a type of virus that is embedded in an application or software, and is installed on your computer along with the installation of that program.

Warms- Worms are self-replicating and can spread to multiple computers connected in a network. You need software along with antivirus and firewall to protect your PC from worms.

Common Types of Computer Viruses

There are four different types of computer viruses classified on the basis of the parts of the computer that cause damage to them. So let’s know in detail about all these types of viruses –

Boot Sector Computer Virus – These viruses are the most common. They damage the boot record on any type of digital storage device, including the computer’s hard disk and all peripheral disks used on them, including DVDs, CDs, and generally floppy disks. These viruses can be loaded onto the computer at any time, but they become active after the computer has used the boot record, that is, the next time it boots.

Once they become active, it becomes very difficult to remove them. The redundancy of floppy disks today has reduced the presence of boot sector viruses.

Master Boot Record Computer Virus – These viruses are special versions of boot sector viruses, in that they primarily affect the computer’s master boot record.

File Infector Computer Virus – File Infector viruses are present on files which are known as executable files. These files contain what they are, such as the extension.exe and.com. Most of these viruses attach themselves to files and then download these files to other users’ computers. With the increasing use of the Internet among computer users, the presence of File Infector computer virus has become quite rampant today.

One of the most difficult aspects about these viruses is that they are retained in the computer’s memory and continue to do their damage on the machine for a long time, perhaps until the entire computer is repaired.

Macro computer virus – These viruses are present on macros, which are data files, usually associated with MS Office programs. Because these viruses are more or less specific to MS Office programs, they are built with the Visual Basic language, which is an inbuilt language for many Office applications. Viruses that have more than one of the above symptoms are called multipartite computer viruses.

How To Protect Yourself From Computer Viruses And Malware

Protecting your data from hackers and other online criminals is becoming more important. New viruses are created daily and many of them are fraudulently targeted to access your personal information.

Computer viruses are software programs designed to invade your computer and delete files, folders, and other data, causing havoc to your operating system. Malware is a type of virus that invades your computer without your consent and causes problems with your files and operating system. Spyware is another type of computer virus designed to retrieve information from your computer without your knowledge and consent.

Fortunately, careful planning and practice can protect your data. Here are some tips to prevent computer viruses, malware and spyware from getting into your computer.

Be careful while surfing the internet – When you are online, be careful about the files and programs you download. Avoid pop-ups and free downloads. Many of these are linked to viruses. Games and social sites are common hangouts for viruses. If you’re not sure about the security of a particular site, it’s a good idea to avoid it.

Do not open unknown emails and attachments – Another very common place for viruses to pick up is email attachments. If you don’t know the sender of the email, don’t open the attachment. All attachments that aren’t unnecessary are malicious, but it’s better to be safe than to regret.

Make sure that the anti-spyware and anti-malware programs are installed and updated – A quality anti-spyware and anti-malware program is well worth the cost, but there is also a free version available to do the job. Make sure you have some form of protection against spyware and malware and update them as needed.

Install a firewall to protect your computer from unauthorized access – Firewalls prevent anyone from hacking your computer, stealing your personal information, or causing other problems. Make sure the firewall is installed and working properly.

Scan your flash drive and external drive before opening the file – Be sure to scan any type of external drive for viruses before you open the file. Please download the information on the CD and DVD before scanning.

Be Careful – If your system is slower than normal, files are missing, or your computer appears to behave abnormally, run a virus scan to see if you can determine the cause. Most often, these issues are caused by some malware.

In addition, we must do our best to keep you up to date with the latest virus and security alerts. There are many internet sites that publish computer virus information, security alerts, and security patches, such as Microsoft.com and cert.org.

Do not use multiple antivirus programs at once – You don’t need multiple antivirus programs at once. Attempting to do more than one will cause a conflict and prevent your computer from working.

Do not click on the suspicious desktop icon – Clicking on an unfamiliar desktop icon can infect your computer with a virus. If you see a suspected icon, perform a full scan for viruses, spyware, and malware.

Use your computer to stop the virus until it is cleared – If your computer is infected with a virus, you may want to keep clicking on different things to use your computer or get rid of the virus. If your computer is infected and you cannot access the antivirus program, turn off your computer and ask a computer expert to remove the virus. The more you try to use your computer, the more the virus gets embedded in your system.

Do not download the executable unless you understand what the executable is – Downloading a program that runs automatically, that is, a file with a .exc file extension, is a very common way for viruses to infect. Know exactly what you are downloading and avoid what you think is suspicious.

When it comes to protecting sensitive data from computer viruses, spyware and malware, the best defenses are prevention and awareness. Unfortunately, new security threats are occurring every day, and protecting your computer with the latest antivirus protection according to secure internet practices is the only way to avoid costly and frustrating virus and malware issues on your computer.
