McAfee analyzed data from voluntary scans of 27 million machines in 24 countries. Finland, Italy, New Zealand, Germany and Denmark were most likely to be protected. Singapore had the least secure computers as well as the highest percentage of users with disabled security protection. The study counted as unprotected machines those that had no antivirus protection installed, or whose antivirus subscription had expired. The U.S. outpaced the average with 19 percent of PCs unprotected, according to McAfee’s study. Users may believe their software subscription is still active when it has expired, McAfee says.”]
