Malware Removal - W32.Downadup/Conficker

Background Information

According to this IT security firm, this high-threat worm exploits the vulnerability MS08-067 in the Windows Server Service in order to spread itself. It also spreads through shared and removable drives. It reduces considerably the protection level of the computer, modifies the security policies of the user accounts and attempts to download another type of malware to the affected computer.

The worm is known to activate on April Fool's Day (April 01), and affects all Windows platforms.

Since it is difficult to recognize (it does not display any messages or warnings that indicate it has reached the computer), it's vital that computer users run the following utilities to scan (and cleanse) their computers.
