After serious research on the best way to define Computer Virus, I realized that one of the most appropriate description was the one i found on Wikipedia “computer virus is a malware program that, when executed, replicates by inserting copies of itself (possibly modified) into other computer programs, data files, or the boot sector of the hard drive; when this replication succeeds, the affected areas are then said to be "infected". Viruses often perform some type of harmful activity on infected hosts, such as stealing hard disk space or CPU time, accessing private information, corrupting data, displaying political or humorous messages on the user's screen, spamming their contacts, logging their keystrokes, or even rendering the computer useless. However, not all viruses carry a destructive payload or attempt to hide themselves—the defining characteristic of viruses is that they are self-replicating computer programs which install themselves without user consent’’.
Hmm, even with all these scary features of computer Virus, I still do not use Antivirus on my Laptop and Desktop and I have never had any course to try to install one. "

I didn’t use Antivirus (AV) because I felt windows already has its inbuilt security platform and I don’t want any software that will always consume my Data couple with other irrelevant reasons…..Do you think its ignorance?.

What I control is my activities and how I interact with the Internet. But it still does not come without system restore on few occasion and not accepting USB. Presently my computer runs Windows 8.1, as secure an operating system as Microsoft has ever released. In addition to its built-in firewall, the OS offers anti-virus protection in the form of Defender (formerly the standalone Security Essentials), plus SmartScreen for protection from malware and phishing scams.
In recent times, the news of virus attack (Spyware, unwanted AD, Malware, Phishing and even the one I read about recently –Ransomeware) is so much that I had to tell myself that there is need for me to get an antivirus ASAP so as not to fall victim with respect to what I use my PC to do.

The puzzle is now how to know the best Antivirus software and how to get the paid version because anything free with respect to software is always a problem.

I have read so many articles on different antivirus, but I felt experience is the best teacher, then, the need for me to ask the technophiles on Nairaland the type of Antivirus they would recommend and why it’s preferred over others.
Kindly note that your sincere and reasonable answer will not only be of help to me, it will also be of great service to others in my shoe and all antivirus users.

Thanks.

I use ESET, its very effective..

I still trust my Security Essential working alongside Defender in Windows 10. USB Security guard protect me from flash related malwares.
