In more technical terms, a computer virus is a type of malicious code or program written to alter the way a computer operates. It’s designed to spread from one computer to another. A virus operates by inserting or attaching itself to a legitimate program or document that supports macros in order to execute its code. In the process, a virus has the potential to cause unexpected or damaging effects, such as harming the system software by corrupting or destroying data.

How does a computer virus attack?

Once a virus enters into your system, it stays dormant until circumstances cause the computer or device to execute its code. The virus reacts whenever you (unintentionally) run the infected program that matches the code. Once the virus explodes into your system, it starts stealing passwords, data, logs keystrokes, corrupts files, spams your email contacts and even sometimes takes over your system, which can be devastating. Keep in mind that a virus can remain dormant on your computer without showing major signs or symptoms.

How do computer viruses spread?

In today’s constantly connected world you can get a computer virus in many ways. Viruses can be spread through email, text message, social media scam links, file downloads and even your mobile devices and smartphones are prone to get infected with viruses through App downloads. To avoid contact with a virus, it’s important to exercise caution when surfing the web or downloading anything. As a general rule, never download text or email attachments that you’re not expecting, or files from websites you don’t trust.

How to protect your system?

It is often said that whenever you buy a computer, consider to hire a computer installation company in Bunbury, as they can install protective and safe software that runs your system efficiently and saves it from severe virus or malware attacks.
