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.
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.
If you have a computer that has been infected, it can be a good idea to call in a professional service to clean up your system. At GeeksAKnockin, for example, the spyware and virus removal service includes the removal of all malicious software, they perform a comprehensive security audit to identify any vulnerability, they evaluate your system to ensure it is performing normally and they provide information to help you make sure that your PC is protected against future security issues.
