I can imagine that you are overloaded with various types of malware. Be wary of computer infections like viruses, trojans and worms which can invade your computer without your consent. W32.Netsky.D@mm is one of the many computer diseases out there nowadays.
It is a mass-mailing worm. Netsky.D propagates through e-mails with spoofed “from” addresses. It sends copies of itself to addresses collected from an infected machine’s local and mapped (C: through Z:) network drive. This threat also tries to eliminate Mydoom infections. To protect yourself from this danger do not open or execute unknown email attachments. And of course keep your antivirus up to date. It is notable that most updated antivirus programs are able to detect and clean Netsky. Additionally, online scanners and removal programs can also be helpful.
