A computer virus is a malicious code that alters other computer programs and files by infecting them with the viral code. The more the infection, the more the virus replicates and multiplies. Depending on the viral code, viruses can range from an annoyance to very destructive entities. The latter is more common and comes in various types.<\/p>\n
What Types of Common Computer Viruses Are There?<\/h2>\n
Viruses come in many variants, each designed for a specific destructive function. The most common types that require a virus cleaner to remove include:<\/p>\n
\n- Boot Sector Virus<\/strong> \u2013 This is a virus of the early days, and its infection is not common on the latest devices. This virus infects the MBR or the master boot record. It gets its way into a system by first infecting the boot sector on a disk or the executable boot file on USB drives.<\/li>\n
- Cavity Virus<\/strong> \u2013 This virus fills empty spaces of code in applications with its code. Since it utilizes empty spaces, this virus does not affect the size of the file or program it infects. This makes it evade antivirus scans that look at the size and date of modification of files.<\/li>\n
- Non-resident Virus<\/strong> \u2013 also referred to as direct action virus, this virus is designed to infect files and then delete itself. It does not hide in the computer’s main memory and does not affect the performance of the system. This is the easiest virus to create and to get rid of. It is also one of the most common virus.<\/li>\n
- Resident Virus<\/strong> \u2013 this is a type of virus that hides in the computer\u2019s main memory. This virus infects targets such as files by intercepting operating system requests and directing them to the replication module. This type of virus is hard to detect and find since most antivirus software does not scan the main memory.<\/li>\n
- Macro viruses \u2013 <\/strong>also known as document viruses, these are viruses that embed themselves in documents that support Macro programs. The virus infects targets after the document is opened. This virus is common in email attachments.<\/li>\n
- Multipartite Virus<\/strong> \u2013 most viruses operate in a single-mode but multipartite viruses operate in multiple modes. That is, they spread through various ways and infect both files and the master boot record. They are also known to deliver multiple payloads. Multipartite viruses are too hard to get rid. If you clean the infected files, the virus still replicates from the boot sector.<\/li>\n
