General Information About Computer Viruses

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.

A virus is simply a piece of code that is placed into a data file. In our bodies, a virus attaches to cells and replicates inside of them, spreading the virus from cell to cell. It works much the same way in a computer, replicating itself and infecting many parts of a computer. It might affect different computer programs or perhaps corrupt data files or even steal CPU time or hard disk space. Sometimes, a virus can actually steal your passwords and usernames. Sometimes, they will access the contact list in your email and send out emails from you containing the virus. This has the potential to spread the virus to other computers.

The vast majority of computer users in the United States use a computer with a Windows operating system. For instance, many people have a PC with either Windows 7 or Windows 8. Because so many people use Windows, most viruses are created to attack these operating systems. So if you have a Mac or use Linux as your operating system, you are far less likely to encounter a virus simply because those creating viruses tend to focus on Windows where they ostensibly get more bang for their buck, so to speak. However there are viruses that attack Macs or Linux users, and those using software to emulate Windows might be susceptible to a Windows virus.

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.

If you have not installed antivirus software on your computer, you should, even if you have a Mac or another operating system. An antivirus combined with a firewall is even better. Your antivirus program often will ask if it can make updates, and you definitely should let it do so. You also need to update your browser, such as Explorer or Firefox, when updates come up. These often have important security updates that will help make your computer more secure.

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.
