Malware is a malicious software that damages the computer operation. It is usually installed automatically or without the user’s consent. Malware is sometimes mistaken for a virus, but computer viruses are just one form of malicious software.


Computer Viruses

Computer viruses connect themselves to legitimate software programs or apps, such as operating system email client, word processor or any other software installed on your PC.

Upon using legitimate software that is virus infected, you are also running a virus code. This will then find other application and software and link itself to those.

It is substantially important to know that any antivirus does not guard you against all threats. It is still needed to be on your guard and avoid to open any email attachments or to download files if you do not know the source.


Worms are like computer viruses that they imitate spreading out infection very quickly. They allow themselves to spread from computer to another computer through the built-in code. They can duplicate themselves without you knowing it.


These are the most hazardous type of malware since their outcome can go further than your computer files and system. Trojans pretend as gentle software that is why it is so easy to download them by a fault.

Usually, Trojans are used to hijack a huge number of systems to begin cyber attacks on banks, email services, and internet service providers among others.


Adware is designed to show unnecessary advertising on your PC, frequently in pop-up forms in your web browser. It can affect other apps too. Ads lead to false websites that contain serious forms of malware.


Spyware is a more sophisticated form of adware that follows your computer usage, monitoring the email you send and the websites you visit. It intends to build a profile that you are interested in so that more ads can be sent to you.

Protecting Against Malware

Get a very good antivirus software and make sure you keep it up-to-date. Change your wrong style of browsing habits. Just open the email attachment from the trusted source. Also, make sure that you only visit highly-regarded websites.

Good browsing habits together with a good anti-malware package will keep you secure most of the time. But you should also create backups regularly. You should also need to wipe your disk drives after a serious virus infection. By doing this, you will be able to bring back a copy of your data.
