Security software firm Kaspersky Lab has predicted a ten-fold increase in new malware for 2008.
Such an increase would mean an extra 20 million malware programs on top of the 2007 year-end figures, said Kaspersky.
Kaspersky Lab said that in 2007, the number of new malicious programs recorded on the internet - including viruses, worms and Trojans - amounted to 2,227,415, a four-fold increase on the results for 2006.
David Emm, senior technology consultant at Kaspersky Lab, said, "in addition to the quantity, the quality of malicious programs is also improving. New and more complex samples, such as the notorious Zhelatin (aka the Storm Worm), are emerging that demonstrate a wide range of hostile behaviour and distribution methods".
