It reveals that in the second quarter of 2015 there were an average of 230,000 new malware samples detected each day, which means a total of 21 million new types in these three months. Compared to the same period last year, where there were 160,000 registered samples, this is an increase of 43 percent.
The majority of these samples are variants of known malware, mutated by cybercriminals to try and stop the antivirus laboratories from detecting the infections. Trojans continue to be the most common source of infection, with 76.25 percent of users infected by this type of malware. This quarter also saw the proliferation of PUPs (Potentially Unwanted Programs) which accounted for 14.39 percent of infections, placed just behind Trojans.
