Viruses, worms trojan horses, etc. can be removed by using special computer programs. These are called anti-virus or anti-malware software. Although most anti-virus software is effective against various malware, it is known as anti-virus software from the beginning. Almost all anti-virus software available in the market is effective against viruses and other malware. All virus programs have certain patterns. Antivirus software stores a list of these patterns. This list is usually made by research. When antivirus software is allowed to run, it looks for specific patterns in various files on the computer system and compares them to its own list. If it matches it identifies it as a virus. Since most viruses only infect executable files, testing them can go a long way. However, a major drawback of this method is that if the list is not updated regularly, it becomes difficult to detect viruses. That's why many anti-virus software tries to detect viruses by examining the behavior of all programs on the computer. The problem with this is that the anti-virus software doesn't know about the software in advance, it identifies it as a virus, which is harmful. For this reason, the world's most popular anti-virus software uses the first method. Some of the popular anti-virus software are Norton, Avast, Panda, Kaspersky, Microsoft Security Essential, etc.
