Ain't no joke: viruses/trojans/ransomware etc do exist & can infiltrate your PC, and savvy users act to guard against them with AV software as the foundation of a layered protection scheme & also with sensible behavior online. Malware relies heavily on users doing stupid stuff. Most of the time you know when you are straying into the murkier waters of the internet. Do you ever think that your sensible behavior is enough to protect you from attacks, and that antivirus software is not necessary?

Malware can be acquired by something as simple as searching for a battery for a digital camera - this happened to me, and I thought I was careful.

I now have antivirus, antimalware and antiexploit software, I changed browsers, and I got rid of Adobe Reader, Flash and Java.

AntiVirus software is an essential part of a complete security model.

You can be as careful as you want, but a hijacked advertisement ('malvertisement') can infect you.

 

Common Sense ('sensible behaviour') is essential, but part of that sensible behaviour is to keep yourself protected electronically as well.

 

Uninstall anything you don't need: Java, Flash and Adobe Reader have all been mentioned as they are the prime targets.

 

Also, use an adblocker such as AdBlock Plus - you'll need to install it individually on all your browsers but that provides another layer of protection.

NoScript is another one - I think NoScript and AdBlock Plus play nicely but I've not got any experience of that so can't comment with any degree of authority.

 

Keep your browsers updated to the latest-and-greatest as well so any known exploits are patched.

I have both in Fire Fox and no problems.

Adblock Plus - Chrome Web Store - Google

Common sense is necessary, but you will need some sort of safeguard at your door - in this case, antivirus software - as well.

Criminals are trying their hardest to infect users that do not "do stupid stuff" as you say, mainly via drive-by downloads.

You can use uBlock Origin which blocks both ads and scripts. No need to use Adblock Plus and NoScript at the same time.

I would not recommend anyone use a computer without anti-virus protection regardless of what other security protection is installed.. Security begins with your computer and it must be safeguarded at that end.
 

Among the ~800 pages of new threat intelligence is a new study that attempts to quantify the benefit of running up-to-date anti-virus (AV) software. The study leveraged data from over a billion systems worldwide and it turns out that systems that do not have up-to-date AV are 5.5 times more likely to be infected with malware than systems that are protected...

Anti-virus Software is DeadReally?

Why should you use Antivirus software?IMO, not having an anti-virus working in real-time in the background defeats much of its intended purpose...to protect a computer and prevent malware infection BEFORE it can damage your system.

How do folks who claim they do not use an anti-virus and never get infected know for certain that their computer is malware free? Many of today's attackers employ advanced techniques which involve sophisticated Botnets, Backdoor Trojans and rootkits to hide their presence on a computer. Without proper security tools including an antivirus which can detect such malware, you can never be absolutely sure your computer has not been infected.

Further, using unprotected computers on the Internet is a security risk to everyone as they are prone to attack from hackers, Botnets, zombie computers and malware infection. When infected and compromised, malware spreads faster and more extensively, distributed denial-of-service attacks are easier to launch, spammers have more platforms from which to send e-mail and more zombies are created to perpetuate the cycle. Using anti-virus software will help minimize the risk and help to prevent the computer from being used to pass on infections to other machines.
