In late 1975, Queen recorded and released A Night at the Opera, taking its name from the popular Marx Brothers movie. At the time, it was the most expensive album ever produced. Like its predecessor, the album features diverse musical styles and experimentation with stereo sound. In "The Prophet's Song", an eight-minute epic, the middle section is a canon, with simple phrases layered to create a full-choral sound. The Mercury penned ballad, "Love of My Life", featured a harp and overdubbed vocal harmonies. The album was very successful in Britain, and went triple platinum in the United States. The British public voted it the 13th greatest album of all time in a 2004 Channel 4 poll. It has also ranked highly in international polls; in a worldwide Guinness poll, it was voted the 19th greatest of all time, while an ABC poll saw the Australian public vote it the 28th greatest of all time. A Night at the Opera has frequently appeared in "greatest albums" lists reflecting the opinions of critics. Among other accolades, it was ranked number 16 in Q Magazine's "The 50 Best British Albums Ever" in 2004, and number 11 in Rolling Stone's "The 100 Greatest Albums of All Time" as featured in their Mexican edition in 2004. It was also placed at No. 230 on Rolling Stone magazine's list of "The 500 Greatest Albums of All Time" in 2003.

Historically, Mac OS X enjoyed a near-absence of the types of malware and spyware that affect Microsoft Windows users. Mac OS X has a smaller usage share compared to Microsoft Windows (roughly 5% and 92%, respectively), but it also has traditionally more secure UNIX roots. Worms, as well as potential vulnerabilities, were noted in February 2006, which led some industry analysts and anti-virus companies to issue warnings that Apple's Mac OS X is not immune to malware. Increasing market share coincided with additional reports of a variety of attacks. Apple releases security updates for its software. In early 2011, Mac OS X experienced a large increase in malware attacks, and malware such as Mac Defender, MacProtector, and MacGuard were seen as an increasing problem for Mac users. At first, the malware installer required the user to enter the administrative password, but later versions were able to install without user input. Initially, Apple support staff were instructed not to assist in the removal of the malware or admit the existence of the malware issue, but as the malware spread, a support document was issued. Apple announced an OS X update to fix the problem. An estimated 100,000 users were affected.

When did Mac OS X experience a large increase in malware attacks?
Answer:
early 2011
