Signs of a virus
The presence of viruses or malware in a system or program manifests itself in different ways, so go right here and find out more. First of all, there is poor performance, crashing of some applications and sometimes even freezing of the computer.

How to prevent and fight a virus
The first thing you should think about to protect yourself from viruses is installing a powerful and effective antivirus software. The latter helps you to detect the presence of viruses in your system. Moreover, the effectiveness of an antivirus is measured by its ability to detect viruses quickly and to eliminate them. You need an antivirus that can destroy even the most sophisticated viruses.
It is also necessary to think about restoring the system and updating the drivers. Updating should be done on a regular basis as it not only improves functionality but also includes security patches that close security loopholes.
Another way to combat the effects of viruses is to back up system data, as sometimes removing viruses can result in the deletion of some important data on the system. Finally, one should avoid suspicious websites as there are a plethora of virus-ridden web pages and online websites that upon being visited spread viruses throughout the system.
