South Korea, 4th in the Olympic 2012 Medal Ranks, But 1st in the Infected Computers Table - According to PandaLabs Q2 Report

- Over six million new malware samples were created in Q2 2012 - Three out of every four malware infections are caused by Trojans - New variant of the "Police Virus" emerges

Berkshire, United Kingdom, August 10, 2012 --( PandaLabs, Panda Security's antimalware laboratory, today published its Quarterly Report for Q2, analysing the IT security events and incidents from April through June 2012. In the second quarter of 2012 alone, more than six million new malware samples were created, a similar figure to the first quarter.

South Korea Tops List of Infections per Country for First Time Ever. The average number of infected PCs across the globe stands at 31.63%, falling almost four percentage points compared to Q1, according to Panda Security’s Collective Intelligence data.

South Korea led this ranking (57.30% of infected PCs) for the first time ever, up by almost three percentage points compared to Q1. China took the second spot (51.94%), followed by Taiwan and Bolivia. The list of least infected countries is dominated by European countries occupying nine out of the first ten places, with the other being Uruguay. The top-ranked country is Switzerland (18.40%), followed by Sweden (19.07%) who are the only two nations with fewer than 20% of computers infected. Norway, United Kingdom, Uruguay, Germany, Ireland, Finland, Hungary and Holland are the other eight countries with the least malware infections.

Luis Corrons, technical director of PandaLabs, states: “The list of least infected countries is dominated by some of the world’s most technologically advanced nations, with the sole exception of South Korea. Even though there may be other factors that influence these results, there seems to be a clear connection between technological development and malware infection rates.”

Countries with the most malware infections

Trojans continued to account for most of the new threats created this quarter (78.92%); worms took second place, comprising 10.78% of samples; followed by viruses at 7.44%. The last place was occupied by adware/spyware at 2.69%.

Interestingly, viruses continued their decline, moving from second place in the 2011 Annual Report (14.24%) to third place (7.44%) this quarter. Worms maintained their second position, rising from 9.30% last quarter to almost 11% this quarter.

When it comes to the number of infections caused by each malware category, Trojans once again topped the ranking, accounting for more infections than in the first quarter (76.18% compared to 66.30%). Viruses came second (7.82%), followed by worms (6.69%). “It is interesting to note that worms have only caused six percent of infections despite accounting for almost eleven percent of all new malware,” says Corrons. “The figures corroborate what is well known: massive worm epidemics have become a thing of the past and have been replaced by an increasing avalanche of banking Trojans and specimens such as the Police Virus.”

The Quarter at a Glance
In the report, PandaLabs highlights several top security incidents that occurred during Q2: the proliferation and evolution of the so-called "Police Virus" from scareware to ransomware, and Flame, a cyber-espionage virus that has become one of the highlights of the year.

The report also covers the latest cases of cyber-crime, such as a hacker attack on Wikipedia users, the exploitation of a major security hole in Iran’s banking system, and the new ways found by law enforcement agencies to fight cyber-criminals - including locating a US hacker through a twitted photo of his girlfriend’s breasts. Finally, it includes information about the latest attacks on mobile phones and social networking sites, the cyber-espionage operations between nations such as the United States and Yemen, or the traditional cyber-conflict between North and South Korea.

PandaLabs ( advises all users to keep their computers adequately protected. With this in mind, Panda Security offers its free tool Panda Cloud Antivirus (

About PandaLabs Since 1990, PandaLabs, Panda Security’s malware research laboratory, has been working to detect and classify malware in order to protect consumers and companies against new Internet threats.

To do so, PandaLabs uses Collective Intelligence, a cloud-based proprietary system that leverages the knowledge gathered from Panda’s user community to automatically detect, analyse and classify the more than 73,000 new malware strains that appear every day. This automated malware classification is complemented through the work of an international team with researchers specialized each in a specific type of malware (viruses, worms, Trojans, spyware and other attacks) to provide global coverage.
