What is a computer virus?
In fact, computer virus is a type of programming that if it can bypass the host's security system, it would eventually infect the whole system by inserting its own code and fast replication, profiteers can access various information from the host system by importing the virus into the host’s system, and they also make many changes to the systems of different users in order to achieve their desires.
There are three types of computer viruses:
1- Macro viruses:
A macro virus can attack various applications and eventually cause a sequence of actions to start automatically when the infected program is opened, the virus is written in macro language and can infect different types of systems due to having different operating systems, as we mentioned, this type of virus causes malicious programs to run once the infected documents are opened, in fact they do this process by entering malicious code into macros that are associated with documents, spreadsheets, and other data files, these types of viruses can eventually send infected emails from the infected system, so that lots of different users’ systems will be infected once they open those emails, and viruses continue to multiply just like biological viruses and infect the whole system, as a result, they are able to infect more and more users’ systems day by day.Also, when this macro is executed in the system, usually all the documents that are in the user's computer are infected and can cause disorder in the existing documents, the first macro virus was spread in 1995 through Microsoft Word and has finally been able to continue to spread and infect various systems to date, there are different types of macro viruses including, the concept virus and Melissa virus, which we are going to describe in the following.
The concept virus:
The first macro virus to be introduced was the concept virus, which targeted Microsoft Word.
Melissa virus:
This virus spread in March 1999 through infected emails and was able to infect many systems in a very short while, so these abilities caused a lot of worries and turned this virus into a huge danger for every user, this type of virus was distributed as an email attachment, and as we mentioned, it was able to spread quickly among different users’ systems, these emails were distributed to the users in such a way that the users thought they had requested the submitted file and opened it quickly, by doing so, their systems would be infected, this type of virus has caused a lot of economic losses, especially to Microsoft.
