24% de PCs en el mundo no tiene antivirus - Security Intelligence Report, volume 14

Today, Microsoft released new research as part of its Security Intelligence Report, volume 14, which takes a close look at the importance of running up-to-date antivirus software on your computer. The research showed that, on average, computers without antivirus software are 5.5 times more likely to be infected.
Antivirus software from Microsoft, McAfee, Symantec and others helps to guard against viruses, remove infections and protect your privacy. It can help protect your computer from malware trying to steal your credit card information, e-mail address book or even the files you’ve saved to your computer. It is one of the most crucial defenses computer users have to help protect against cybercriminals.

If you have been using computers as long as I have, long before almost every device was constantly connected to the Internet, you’ll recall the days when viruses were typically spread via sneaker-net, through infected floppy disks. You had little to worry about because the number of threats was miniscule and their payloads were typically benign compared to the threats we face today. The digital world has changed quite a bit since that time. In the past decade, Internet usage has gone from 361 million people online to more than 2.4 billion. People spend more time online than ever before and our reliance on computing has turned our tablets, phones and laptops into time capsules filled with confidential information about our lives.
The security of computers has also steadily improved. But cybercriminals have adjusted to this new norm and increasingly use deception tactics to trick users into installing malware on their computers. They bundle malware with illegitimate software activation key generators, spread malware through compromised websites and use social engineering to send malicious documents to potential victims via e-mail and websites. In the fourth quarter of 2012, Microsoft detected and removed malicious documents such as Adobe Acrobat documents (PDFs) and Word documents, commonly sent as attachments through e-mail, from almost 3 million systems.
