A computer virus works similarly to the flu virus: it’s highly contagious, you feel
run down, you need more sleep and rest than usual and it’s difficult to perform
even the simplest of daily tasks. Likewise, a computer virus interferes with the
performance of your device by replicating itself and spreading throughout the
operating system. A virus can damage programs, delete files and reformat or
erase your hard drive, which results in reduced performance or even crashing
your system entirely. Hackers can also use viruses to access your personal
information to steal or destroy your data.
As society becomes more dependent on technology, it’s important to educate
yourself, family, friends, employees and co-workers about safely navigating the
internet. Here’s a quick guide on everything you need to know about computer
viruses – from what they are and to how to spot one, to what you should do if
your device is infected.
