No Adults do not need parental control software, but Parental Control/website category blocking software can block naughty sites which will reduce the chance of getting a virus, or spyware infection which naughty sites and file sharing sites are more known to have compared to Google.
Website blocking software can be useful if a site always try to infect your computer with a virus every time you visit the website, so you can easily block it.
Plus, it prevents adults from viewing illegal content "by accident" like "underage porn, bomb making, cults, terrorism sites and illegal material" which can land the viewer in jail for many years if the judge and jury don't believe they watch the stuff by accident by clicking a link by accident or mistyping a link.
I use the free OpenDNS account which I configure to block sites with these categories "academic fraud, alcohol, nudity, pornography, dating, p2p/files sharing, sexuality, tobacco, adware, drugs, gambling, parked domains, tasteless, and weapons." since they don't interest me much, and to prevent me from viewing the sites which I do not trust fully because of the category.
I also configure OpenDNS to block Malware/Botnet, Phishing, and Suspicious Responses to also block weird websites.
