The company ESET has released a list of hazards that often infect users' computers in October this year. The first three items took risks, which invariably led to this year's rankings, and only in October were the cause of almost 24% of all detected infections.

The October list of threats opens recognized by almost every surfer Conficker worm, such as penetrating a computer through vulnerabilities in Windows (patched by Microsoft over a year ago). New mutations Conficker can also infect files via automatic start of the media. After implanting the system retrieves from a network worm malicious adware, disables the Windows firewall, HTTP server runs on different ports and allows you to gain control over an infected machine.
The second threat is from the October list of family programs, INF / Autorun attacking undetected through the files of various types of automatic take-off media.

These programs to steal logins and passwords online players MMORPGs such as Lineage, World of Warcraft or Second Life. These three threats for several months is the largest number of infections. Just last month Conficker, INF / Autorun, and PSW.OnLineGames were the cause of almost 24% of all detected infections.

Probably contributes to the fact that the use by many users of pirated copies of Windows. Cut off from the site update and are often deprived of any anti-virus protection are easy targets for Conficker and other threats. Such users often unknowingly become dealers of viruses, worms, Trojan horses, etc., building further statistics on the most active threats in the network.

Changes made by Qhost very often prevent successful connection to a computer server manufacturer's security software (eg antivirus software) to download from the current database of signatures.

The list of risks created by the community ThreatSense.Net over 10 million users who send samples behaving suspiciously applications to ESET labs. Where they are subjected to analysis on the basis of which creates the necessary signatures of new viruses, and reports on the risks existing in the network.
