Remove Worm.Conficker

Win32/Conficker is a worm that infects other computers across a network by exploiting a vulnerability in the Windows Server service (SVCHOST.EXE). If the vulnerability is successfully exploited, it could allow remote code execution when file sharing is enabled. Depending on the specific variant, it may also spread via removable drives and by exploiting weak passwords. It disables several important system services and security products and downloads arbitrary files.

Conficker.C is the latest modified version of notorious Conficker worm. This dangerous worm can cause serious damage to the system, that’s why it should be avoided at all costs. Especially users have to be very careful on April’s All Fools’ Day, because Conficker C is scheduled to perform it’s malicious actions on this day. As we have already mentioned, Conficker.C is a very dangerous worm. Detection and removal of this parasite might be very difficult.

Once installed and active, Conficker.C may perform many harmful acts on user’s computer. It will probably disable security software and processes, restrict access to security-related websites and block online anti-spyware scanners. What is more, Conficker.C can disable Windows Automatic Update and block access to Windows Security Center. But the worst news is that Conficker.C may download and install additional malware, spyware or similar infections. System security could be seriously comprimised. Private information can be stollen or deleted without user’s permission and knowledge. It should be already obvious, that Conficker.C must be removed as soon as possible.
