A computer virus is a piece of code that is capable of copying itself and typically has a detrimental effect such as corrupting the system or destroying your data contained in the computer. Similar to the flu virus, a computer virus can be quickly replicated, and attaches to programs, documents, Internet downloads and files, and can be spread by opening e-mails, attachments, downloads and scam links. Mobile devices are also susceptible to viruses via app downloads.
A good rule of thumb is to never download programs, apps, or attachments that you are not familiar with, are not expecting or don’t come from a trusted source, and never click on links you don’t recognize.
It's essential to have virus protection software to protect your computer or device from incoming threats, which will also in turn provide a warning when a potential threat is detected. Below is a partial list of security vendors who offer anti-virus software to help keep your computer and mobile devices secure. Be sure to keep your security software updated to ensure maximum protection and performance.
