Viruses: How They Can Harm Your Computer

By Frankline Bell


We all have heard of computer viruses and, of course, we know they aren't a good thing to have on one's computer, but most of us don't really know how a virus works. Here is some basic information about computer viruses and some helpful tips for preventing viruses and even finding a cure.

Basically, a virus is a computer program and like all programs, it is created with code. Within the code, there is a piece of it that is designed to attach to files or programs and replicate. This means it keeps replicating and attaching to more and more files or programs or begins to clog up your hard drive space or slow down the CPU or central processor of the computer. There are even viruses that are designed to seek out and steal passwords. Many viruses are spread via email, and the virus gets into your email and begins sending out emails to all of your contacts. These emails also contain the virus and it just spreads further and continues to infect more and more users.

Microsoft Windows, which is the mostly widely used operating system, is most often the target of those who create these viruses, and that is simply because there are more people to infect. Apple Macintosh users, Linux users and those who use other operating systems have often felt immune to virus and malware attacks, but this is not necessarily true. While there are certainly fewer viruses out there written specifically for Macs or Linux, they do exist. Also, if you use a program that was created to emulate a Windows operating system, you often can be at risk for various Windows viruses.

The good news is that with a bit of caution, you can avoid many viruses. For instance, resist clicking on those pesky pop-up ads, especially the ones that say things like "your computer is at risk," or "virus detected." These ads often contain a virus, and when you click on them or click and download something, generally you are downloading a virus or other malware. Pop-ups are not just pesky; they can be hazardous to your computer's health. You also need to be wary with email. Delete emails from unknown senders and if a contact sends you an email that looks odd, maybe it has misspellings in the subject or no subject, just delete it. If you see an odd post on social media, the same rule applies. Many people get "hacked" on sites such as Facebook simply by clicking on a link, so always be careful when you click.

Having a good antivirus program installed on your computer can be an excellent way to protect your system. Installing an antivirus program with a firewall can provide even more security. Make sure that you allow the program to make updates, as these help make your computer more secure. Updating to the latest version of your favorite browsers is also a good way to help prevent viruses. Antivirus programs cannot protect you from everything, but if you are cautious and have antivirus software in place, you are much less likely to become infected.

While no one wants a computer infected with viruses or other malware, it happens. When your system has been compromised, simply contact the computer repair specialists at GeeksAKnockin. They have a comprehensive virus and spyware removal service and for one flat fee, they generally remove all malware within 90 minutes or less. The service includes the removal of malicious software, a security audit to check for areas of vulnerability and a system check to make sure the computer is running normally. In addition, they will check and see that all Microsoft and third party security patches have been installed and provide you with information about how to keep your PC protected.
