Computer viruses are common and can affect your computer in many ways depending on how they spread. Viruses spread around the internet through email attachments, downloads, or even online games. There are also viruses that infect other computers on a network, which is why it’s important to keep your antivirus software updated with the latest virus definitions so you’re protected from any new threats! Besides, so it is important to be aware of the different methods that you can employ to protect yourself from them.
Let’s role it down;
More often than not, when we are performing some work or research on our personal computer and suddenly we are overwhelmed with anti-virus alerts or even worse, a screen locker virus that is blocking accessibility. In any case, as unimaginable as that sounds, we encounter computer viruses that perform those crippling functions. A computer virus in simple terms referred to as a type of malicious software program that when executed, duplicates by multiplying itself or infecting other computer programs by transfiguring them.
Computer viruses usually have some adverse effects on the host computers including corrupting of data, accession of hard disk space, spamming of email contacts, logging keystrokes as well as declaring the computer useless. Remarkably, computer viruses are self-replicating computer programs that install and reinstall themselves without the user concession. Subsequently, just like the same way viruses require a host cell to replicates itself, computer viruses may not reproduce and spread without programming particular files or documents. The other technical terms, computer viruses are maliciously designed code or programs drafted to alter the functionality of a computer to eventually spread to other computers.
Typically a computer virus attaches itself to a legal program or documents that probably support macros so that it can execute its code. The moment a virus successfully attaches itself to a document or file, it would stay dormant until situations cause the computer to administer its code. With that respect, a computer virus would overwhelm your computer the moment one runs the infected program, eventually causing the virus program to be administered.
Incidentally, computer viruses can predominately stay dormant in the computer, but the moment the virus infects your computer alongside others in the network. Further, over the period of time, it is evident that computer viruses may spread in several ways, some more pronounced than others. Computer viruses can spread from downloads off the internet; social media scam links, e-mail attachments, or removable media. As a matter of fact, computer viruses usually disguise as attachments shared on social platforms such as comical images, special greeting cards, or audio as well as video files.
Meanwhile, there are varying effects of computer viruses manifested on computer systems ranging from more pronounced or complex while others are simple. The effect of computer viruses depends on the severity of the computer that has been infected. In any case, computer viruses impair particular programs and applications leading to the inability of the computer to function or access the programs efficiently. In other instances, the programs may provide incorrect output.
On that account, computer viruses may infect the data stored in the hard drive resulting in its crashing. As such, the effect would lead to the formatting of the hard drive. Needless to say, the file is also a prime target for computer viruses, and what actually happens is that the viruses modify, delete, or even corrupt the files causing inaccessibility of the files. One of the fundamental concepts about computer systems is the level of integrity. With respect to that, computer viruses pose great harm to a computer system’s operations thereby jeopardizing its integrity.
Subsequently, some computer viruses may not necessarily have an effect on the system integrity but in certain instances consume the computer’s memory slowing down the computer. Computer viruses have the capabilities of damaging the BIOS a system program hardcoded within the motherboard that is bestowed with the responsibility for the more basic function of a computer.
In conclusion, Computer viruses have been around since the late 1980s and they’ve evolved to grow with the digital age. They now affect more than just computers, but smartphones, tablets, smart TVs—any device that can connect to a computer network or other devices through WiFi. There are several ways in which these bugs spread from one machine to another including email attachments, malicious websites, USB drives and even social media sites like Facebook. To help protect your computer system against malware attacks we recommend downloading antivirus software as well as installing an anti-malware tool on your mobile device such as Malwarebytes for Android or iOS security app. It is also important not to click on links within emails coming from unknown sources; don’t visit suspicious websites
