Viruses are a persistent problem. A single mistake, such as clicking on a
dodgy link or opening an unknown file, is all it takes for your
computer to become infected.
Once a virus is on your system, it can
steal personal data or even lock your files entirely. Fortunately,
there are some simple steps to remove it. Plus, we've got some top-notch antivirus recommendations to prevent it from happening again.
