In modern day life, many people find themselves being too busy to properly maintain their PCs, or simply expect the PC to automatically run through the maintenance. Although PCs have become a lot more self-sufficient, they do still require some chores to ensure they are completely protected from any threats. One of the most important chores that must be kept on top of is running regular virus scans and keeping your anti-virus completely up to date. New threats are being released multiple times per day and so even if your anti-virus is out of date by 1 or 2 days, you leave yourself vulnerable to many types of threats. Even though your anti-virus is up to date, the viruses will not be detected if you have them on your system unless you run regular virus scans, which could lead to major problems.
