    The Different Types of Viruses in Computer

    There are many different types of Viruses in Computer Types and knowing which types to look out for is essential. Here are a few: Ransomware, Multipartite, and Resident viruses. These types of viruses can cause damage to your computer and can change the way other programs work. [1]They also change the start of the program and change control jump.

    Resident viruses

    Resident viruses infect computers by installing malicious code directly into the system’s memory. These viruses spread rapidly and can damage the computer if they’re not detected and removed early. [2]The two main types of resident viruses are fast infectors and slow infectors. The former can cause massive damage quickly and are more obvious, while the latter can be much more subtle.

    Resident viruses can also infect your system by making use of shared or downloaded files. Once activated, they spread to other files on your system, sending emails to contacts without your knowledge. [3]You may also notice strange desktop files or strange web browser behaviors. In some cases, you can detect a resident virus by installing a good anti-virus software program.

    Boot-sector viruses target the master boot record (MBR), which is responsible for booting your computer. They can also affect the partition table of your hard disk. [4]Once activated, a boot sector virus can cause boot-up problems, poor performance, and unreadable hard disks. However, modern computers are built with safeguards to protect the boot sector from infection.

    Another type of resident virus is a browser hijacker. It changes the home page URL and search preferences on your computer and redirects you to malicious websites. These sites collect your personal data and make money for the attackers. [5]Resident viruses can also sit in memory of your computer until the payload is delivered. They may remain dormant until a specific date or time, but that’s not a guarantee that they won’t infect your system.

    Viruses usually exploit vulnerabilities in the operating system or the application code. To avoid infection, keep your system updated and run free virus scans regularly. [6]Viruses can also infect devices connected to the internet, such as smartphones and IoT gadgets. For your protection, always update your operating system and make sure all hardware is up-to-date.

    Polymorphic viruses can change the way the computer runs. Viruses with these characteristics can evade the detection of antimalware programs by changing their code and changing their signature.

    Multipartite virus

    A multipartite virus is a computer infection that attacks several executable files at once. They are very dangerous because they can make a computer inoperable. These viruses first appeared in 1989. They spread via boot sectors and executable files. When a computer starts up, the virus attaches itself to the boot sector and executes destructive payloads across program files.

    The multipartite virus can cause major damage if it is not detected and removed on time. The symptoms of infection range from a completely blank screen to constant notifications about low memory. [7] Users may also have difficulty shutting down their computers or detaching the battery. The virus can even change the extension of files without their consent.

    Multipartite viruses are very difficult to remove. Depending on the variables present in the virus, they may infect the boot sector, program files, or both. Fortunately, there are several ways to remove these infections. [8]The first step is to install trusted antivirus software. Another method is to clean up the boot sector and the entire disk.

    Multipartite viruses have several different genetic structures. Some are similar to plasmids in nature. Some have RNA-dependent RNA polymerases. [9]These viruses may have shared genetic material with other viruses. They may display similar systems organization to cellular metabolism or gene regulatory networks.

    The first step in preventing multipartite virus infection is to install trusted antivirus software on your computer. This software will scan and remove the virus quickly and completely. It will also ensure the safety of your computer. [10]The best way to remove a virus from your PC is to use antivirus software and follow safety guidelines.

    Multipartite viruses have specific features that enable them to spread. For example, they infect certain sessile marine organisms like seagrasses. Positronia oceanic is one such type of sessile sea grass. [11]This plant has vast meadows of clonal individuals, which is perfect for spreading the virus from one host to another.

    Another type of multipartite virus is a web scripting virus. It targets popular websites and overwrites code, inserting links to malicious software, or posting on behalf of the victim. Once installed, a multipartite virus can infect hundreds or thousands of files on the computer. It is also known as a boot sector virus. [12]These viruses enter the computer’s memory without the user’s knowledge. They can bypass anti-virus software, because of the way they modify the code whenever they perform an action.

    File infector virus

    File infector viruses are among the most common types of viruses that infect computer files. They work by copying themselves onto executable files and overwriting parts of their code. In some cases, they can even reformat a hard drive. [13] Another example of a file infector virus is the Romeo and Juliet virus, which creates a duplicate virus file with the same name and extension as its original file.

    File infector viruses usually infect executable files and memory and stay in the system for a long time. The good news is that there are now removal tools that can detect these viruses and help you remove them from your computer. File infector removal software works by booting into a DOS mode and unlocking system files, including the infected ones.

    File infector viruses are a significant threat for computer users. These viruses can damage your system and steal data from your PC. Some of them will attach themselves to selected program files, while others will infect any program. Computer security experts have noted that computer infectors pose a significant threat to your system and should be eliminated as soon as possible.

    A file infector virus attacks a computer’s boot sector, which is responsible for pointing the computer drive to the operating system. Once infected, the boot sector will become corrupted, rendering the machine unusable. These viruses often spread through a malicious USB device, which a user plugs into their computer. [14]Fortunately, most browsers have built-in defenses against malicious web scripts, but older versions of browsers have vulnerabilities that allow attackers to run their malicious code locally.

    File infectors infect executable files by overwriting the code inside them. Some are designed to run only on a small number of times each day, which allows them to avoid detection. Some of these viruses can even remain undetected by the earliest detections. Virus researchers are now working to develop a countermeasure for these types of viruses.

    Infections from file infectors can result in a damaged hard disk. These infections can also cause a number of problems in the computer’s system. [15] These infections can render files useless and will eventually cause your computer to run slower.


    Ransomware is a type of virus that encrypts files on a victim’s computer. According to the InfoSec Institute, these encrypted files cannot be opened without a mathematical key known only to the attacker. Usually, ransomware presents a message to the victim explaining the situation and asking them to pay the ransom in Bitcoin.

    Initially, ransomware targets individual systems. But in time, cybercriminals began targeting businesses with the threat of ransoming critical information. By threatening to expose confidential data, ransomware can cause businesses to lose productivity and revenue. Fortunately, there is a way to avoid the majority of ransomware attacks.

    The most common way to get infected with ransomware is to open phishing emails. These emails impersonate a trusted contact or organization to trick unsuspecting individuals into downloading malware. They may even include fake invoices, order forms, and receipts.

    The Peaty ransomware is one of the most common and destructive ransomware infections. This virus encrypts the Master File Table (MFT) and the files stored in it. It spreads itself using a backdoor in Ukrainian accounting software. It then asks its victims to pay a ransom in Bitcoin to undo its changes.

    The earliest ransomware attacks appeared in the late 1980s. The first ransomware families included AIDS and PC Cyborg. The first versions of these ransomware were easy to reverse, and few variants emerged over the next decade. However, in the last decade, a few more variants have emerged. One of these, called Goede, used weak RSA encryption.

    Typical anti-virus software does not protect users from ransomware, and many developers continue to tweak and write new versions of the malware to avoid detection. Many ransomware signatures are so complex that traditional anti-virus programs fail to catch them. As a result, it is critical to have up-to-date endpoint protection.

    Advertising is another common way to introduce ransomware into a computer. Advertising is a method of spreading malicious code without user interaction. These malicious ads are distributed via criminal servers that catalog the details of a victim’s computer and choose the most suitable malware to deliver to it. This malware often uses an infected frame to redirect the user to the exploit landing page. Afterward, the malicious code will attack the victim’s system via an exploit kit.
