Install an antivirus program, is it really necessary?

Yes and no.
In other words, an anti-virus program is useful, but it may not be paid.
Also, always keep in mind that any antivirus, even the best, can never guarantee 100% that you are not the victim of a hacker, scam, etc.


Global network security systems, including Google and other search engines, are always very vigilant in fighting Viruses, Malware, Worms, Trojan horses, Spyware, Adware, Malware contained in images, etc.

On the other hand, even those who produce viruses and invent scams are always looking for new forms of microprograms to deceive the protections.
