1.7 percent of Windows PC were infected with malware in Q4 2013Written by Mark Wilson on May 07, 2014 - 07:41AM @MarkWilsonWords
Microsoft has published its sixteenth 6th Security Intelligence Report covering the period July through December 2013. The bi-annual report shows that there has been a general increase in security problems across the technology industry, with the number of vulnerabilities jumping by 12.6 percent compared to the same period last year.
This can be attributed at least in part to an increase in transparency, meaning that more application vulnerabilities are now being reported -- it is difficult to guage what the increase is in real terms (or even if there has been one). Things start to get interesting when looking at "exploits", which Microsoft defines as "malicious code that takes advantage of software vulnerabilities to infect, disrupt, or take control of a computer without the user’s consent and typically without their knowledge".
Malware appears to be on the increase. In the third quarter of 2013, an average of 0.58 percent of Windows were infected with malware, but by Q4 this increased threefold to 1.7 percent. The increase is being partly attributed to the prevalence of the Rotbrow malware, and Microsoft expects infection rates to drop again in 2014.
Every version of Windows saw a marked increase in infection rates between Q3 and Q4. XP from 9.5 to 24.2 percent, Vista from 5.3 to 32.3 percent, Windows 7 from 4.9 to 25.9 percent, Windows 8 from 2.1 to 17.3 percent, and Windows 8.1 made its first appearance with 0.8 percent.
