Hey Pazsion, Welcome to the forums.
What is your problem exactly?
igmp icmp. udp. aren't normally malware attacks.. they are a way of doing things.. I'll try to outline them for you.
IGMPThe Internet Group Management Protocol (IGMP) is a communications protocol used to manage the membership of Internet Protocol multicast groups. IGMP is used by IP hosts and adjacent multicast routers to establish multicast group memberships.
ICMPThe Internet Control Message Protocol (ICMP) is one of the core protocols of the Internet protocol suite. It is chiefly used by networked computers' operating systems to send error messages—indicating, for instance, that a requested service is not available or that a host or router could not be reached.
UDPUser Datagram Protocol (UDP) is one of the core protocols of the Internet protocol suite. Using UDP, programs on networked computers can send short messages sometimes known as datagrams (using Datagram Sockets) to one another. UDP is sometimes called the Universal Datagram Protocol.

If that doesn't answer your question, could you please post it more clearly

Hope this helps!
