According to the PandaLabs Quarterly Report [PDF] for Q2 2013, malware creation reached record levels in the second quarter of the year, with 12 percent more malware created in Q2 2013 than in Q2 2012, and 17 percent more malware created in the first half of 2013 than in the first half of 2012 (h/t Softpedia).
The report also states that Trojans accounted for 77.2 percent of all new malware created in Q2 2013, followed by worms at 11.28 percent and viruses at 10.29 percent.
Similarly, Trojans accounted for 79.7 percent of malware infections, followed by viruses at 6.71 percent and worms at 6.06 percent.
"Cybercriminals use Trojans as a key tool to infect users, continually introducing changes to avoid detection and in many cases, automating the process of changing the Trojan," PandaLabs technical director Luis Corrons said in a statement. "They use scripts and special tools in order to change the binaries run on victims' computers to evade the signature-based detection used by anti-virus firms."https://o1.qnsr.com/log/p.gif?;n=203;c=204650394;s=9477;x=7936;f=201801171506010;u=j;z=TIMESTAMP;a=20392931;e=i
