It’s totally naive to think that installing antivirus is merely an option these days. Responding to dynamic propagation and continuously increasing sophistication of cyber threats at large, necessity of having an AV program at one’s disposal has definitely become an inalienable attribute of a modern user and is not up for discussion. Viruses are literally everywhere, thriving in the depths of the worldwide web and never abandoning the attempts to infect computers, which is actually what they are intended to do in the first place. Moreover, you don’t necessarily see obvious signs of their activity as they may reside latently in your system and gradually destroy it from the inside or stealthily harvest your private data. This is another relevant reason why it’s critical to have a reliable antivirus installed, because otherwise you cannot possibly spot and handle these infections. The present-day antivirus programs efficiently address some of the issues that used to make people doubt about reasonability of using them: they are no longer affecting PC performance nearly as much and can even contribute to optimizing and improving computer usability. The latest cutting-edge antivirus trends are about proactive defense, heuristic virus detection and cloud computing security.
Whereas different antivirus clients may provide specific sets of functions, there still are the common ones that are mandatory for this sort of software. Along with high virus detection and removal scores, the best antivirus application should be intuitively simple to use and ‘light’ enough for the average computer. The most relevant criteria we take into account when rating antivirus software are as follows:
