Panda Anti-Rootkit has been chosen as the most popular free software tool in Europe.

The German IT magazine PC Welt organised a tournament to choose the continent's most popular free software tool, selecting one solution per participating country. Panda Anti-Rootkit represented Spain (where Panda Security has its global headquarters) and won the title after beating Switzerland in the final.
Panda Anti-Rootkit is a solution designed to detect hidden processes on the system easily and transparently, and identify known and unknown rootkits.
Unlike other anti-rootkit tools that "reveal" hidden objects, Panda Anti-Rootkit positively identifies known and unknown rootkits and gives the option of disabling them (including their associated registry entries, processes and files).
Rootkits are designed to hide objects such as processes, files or Windows Registry entries. This type of software is not malicious in itself, but is used by malware creators to cover their tracks in infected systems. There are types of malware that use rootkits to hide their presence on a system.
In 2005, the first examples of malware that used rootkits (as external tools or techniques within its code) emerged in order to evade detection. Bots, adware and spyware added these characteristics to their own, a trend that has continued to increase.
"Rootkits are a symptom of the new cyber-crime malware dynamic: for malware to be exploited for financial gain, stealth is of vital importance," says Jeremy Matthews, head of Panda Security's sub-Saharan operations. "Rootkits enable malware to remain hidden on a computer for much longer without being detected so it is an absolute necessity that users are able to detect and delete them as soon possible."
