Computer Virus and its symptoms

A computer virus is a malicious program that self-replicates by copying itself to another program. In other words, the computer virus spreads by itself into other executable code or documents. The purpose of creating a computer virus is to infect vulnerable systems, gain admin control, and steal user sensitive data. Hackers design computer viruses with malicious intent and prey on online users by tricking them.

How a virus can enter our device?

One of the deal methods by which virus spread is through emails- opening the attachment in the email, visiting an infected website, clicking on an executable file, or viewing an infected advertisement can cause the virus to spread to your system. Besides that, infections also spread while connecting with already infected removable storage devices, such as USB drives. 

There are two types of ways in which viruses operate, as soon as they land on a news device they begin replicating, while the second type plays dead until a particular trigger makes the malicious code to be executed. Thereby it is highly important to stay protected by installing a robust antivirus program.
