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.
While there are millions of viruses out there, preventing them is not as difficult as you might think. Take email, for example, which is where we encounter many viruses. Often a friend or contact will send an email with a corrupted link on it. Click on this link and you are downloading a virus to your computer. The virus will then attach to your entire contact list and send the email to each one of your contacts. So, it is wise to not click on any email or link within an email unless you trust that it is legitimate. If an email looks odd, it probably is, so just delete it rather than risking infection. Pop-up ads are another hot spot for viruses and clicking on these can definitely cause a virus to get downloaded to your system. Anytime an ad promises something too good to be true or claims that your computer is infected, it's all a scam.
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.
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.
