There are multiple risks that come along with using the Internet on devices such as the PC and mobile phones. Each individual using the Internet needs to be aware that there are risks and the multiple threats lurking around that we are vulnerable to when we use the internet, which is why internet security is so important. Most of the time when we communicate using a computer, we are unaware of the fact that we are taking these risks.

Internet security is more of a consideration for IT professionals who do most of their work on computers and store their entire databases on computers. However, simply storing data is the death knell for them because cybercriminals know that attacking IT computers can be very profitable. This applies to all business users who need to be aware of the attacks they may come across. Talking about how to find a solution to enhance the system, you need to be optimal with your requirements. Before you install an Internet security on to your device, you need to make sure that they are effective on three major aspects which are: incidence response, intrusion detection, and penetration testing.

There are various types and kinds of programs and apps which may have hidden malicious content in them. These are some of the topmost ones that PC and mobile users need to be aware of:

Virus
A computer virus is a program that can replicate itself and can infect a computer without the permission or knowledge of the user. A computer virus has two major features, it can replicate itself and it can attach itself to another system file. There are quite a few signs of a virus-infected computer. A few indicative signals that your computer may have been infected by the virus include extensive pop-up ads, random hard drive crashes, and slow responses.

Malware
Short form for malicious software, malware is a software used to gain access to private computer systems, gather sensitive information, destroy computer operations, or pop up unwanted advertisements. Malware is defined by its malicious content acting against the requirements of the computer user.

Trojan
Trojans might initially appear to be a beneficial software but will actually inflict damage once installed and run on the system. Users are always tricked to open them because it wants to steal information, alter it and cause difficult problems on your computer by just pretending to do nothing.

Botnet
A botnet is a network of computers that are infected with malware. Cybercriminals use special Trojan viruses to breach the security of multiple user computers and assume control of each device. They then set about organizing all the infected devices into a huge bot network which can be managed remotely and used to inflict damage.

Spyware
This is a software designed to gather data from your device. It can share your personal information with a user who has malicious intent. Hackers can get spyware onto your device in many ways. It can enter your device in the form of a trojan, when you interact with legitimate programs. They also exploit and compromise tracking cookies and infest your devices through system monitors. Once the spyware gets onto your device, it can cause many issues.

Worm
A computer worm is a self-replicating standalone malware program which spreads to other computer systems. It usually uses a computer network to spread itself by relying on the security failures of the target computer to access it.
