The 5 Most Common Types of Viruses
Computer viruses are those malicious programs that once they infect your computer, they will start causing mass destruction to your PC. Similar to biological viruses, they can multiply in various ways and develop from one type to another. Since there are hundreds of viruses out there, here are the five basic types of viruses that people are most likely to encounter, in order to make the identifying process easier.
Trojan Virus
Worms
Macro Virus
Boot Sector Virus
File Infector Virus
Trojan Virus – This virus appears to be nothing more than an interesting computer program or file of a user who’s interested in collecting audio files. Once this virus enters your computer, it doesn’t reproduce, but instead makes your computer vulnerable to malicious intruders by allowing them to access and read your files. A Trojan horse must be sent by someone or carried by a program or software of some sort. The malicious functionality of a Trojan horse may be anything undesirable for a computer user, including data destruction or compromising a system by providing a means for another computer to gain access, thus bypassing normal access controls.
Worm A Worm is a virus program that copies and multiplies itself by using computer networks and security flaws. Worms are more complex than Trojan viruses, I should say, and usually attacks multi-user systems. It can spread over corporate networks via the circulation of emails. Once multiplied, the copied worms scan the network for further escape and will then cause errors on the network.
Macro Virus – This type of virus usually comes as part of a document or spreadsheet, more often found in an email. Many of the current macro viruses are written in this language and attached to Word documents. This capability is powerful, but allows viruses to be written and executed much more easily than by using other methods.
Boot Sector Virus – A virus which attaches itself to the first part of the hard disk that is read by the computer upon start up, which are normally spread by floppy disks. In time, they can spread to other readable disks. Booting problems and start up problems, problems with retrieving data, computer performance instability and the inability to locate hard drives are all issues that may arise due to a boot sector virus infection.
File Infector Virus As the name indicates, this type of virus was designed to avoid detection by antivirus software by changing itself internally. Upon running a program that has been corrupted by a file infector, the virus copies the malicious code and applies it to other executable applications on the computer. Files that are the most vulnerable to this type of infection have the extensions of EXE. and .COM, though any file is capable of execution can be infected.
How to fight some of these viruses is still completely a puzzle for anti-virus makers. However, knowing a little about your enemies could be an advantage to get vital information on how to defend your computer from those threats. Read on Virus Removal Help – How to Remove Viruses Easily From Your PC? in order to become more familiar with the steps on how to remove the common types of viruses from your computer.
Handling Viruses with PC Support Provider
Way back into earlier years of computer, when mostly used was DOS command to operating system, viruses on these days has some ways not to be detected. Specifically the “Stealth” virus, which it is capable of hiding itself from the computer users, and most likely to the anti-virus. Through intercepting to the system calls which are responsible for the file reading. They can successfully give you fake information which is becoming legitimate codes for the computer system. Anti-viruses were useless then.
Evolution of the computers comes. With the presence of viruses, Technical Computer Supports dont stop discovering solutions to this problem. They come up with the discovery of Windows. They replaced the use of DOS command to Windows. Bur of course with the computer evolution of computers comes with the evolution of the virus too. Some viruses still have the capability of hiding themselves even with the presence of Windows. They can efficiently hide themselves and can work with the Windows this virus are called “rootkits”
Technical Computer Support used some tricky actions to overcome the rootkits and to save computers from menace. Rootkit mainly attacked the system, install it there and hide itself. The work of anti-virus then was to detect the virus, but before they can detect the virus, they are already moving actively to the software, and after they knew it, the rootkits already intercepted with the programs used to detect them. Using anti-virus then doesnt guarantee a complete protection of computers, especially if rootkits virus was the one intercepted with you software.
Rootkit Revealer was invented. But cannot totally eradicate the rootkit, can only detect that something is hiding within your system. This program was designed to destroy the rootkit, but fails to do so. This was called Microsoft Rootkit Revealer. It does gives a little help, further management with the Technical Computer Support is necessary. UnHackme or other anti viruses with rootkit detection was advice by the Technical Support Group to be installing in computer because it does help. UnHackMe are designed compatible with other anti-virus and also designed not to fight with the rootkits so it can work nicely with another anti-virus. Sort of back-up to each other so system can be of less exposure to viruses. UnHackMe should be installed before anything else, serves as a guard to the system and it watches the system process, taking all controls to the system before others. It can maliciously fools the virus, can detect and destroy rootkits attempts. Thats what Technical Computer Support was suggesting during those days.
By blocking the rootkits before it gets loaded to the memory and passing the control to the anti-virus, the attempts of the viruses becomes easier to detect and remove any further intrusion. UnHackMe are capable of removing rootkits who tries to intrude the software. A nice work-up with Technical Support and installation of UnHackMe and other anti-virus was the remedy before in order to prevent viruses from further intrusion, for experts cant find a way to directly fight the rootkits before.
