• Worm

Answer explanation

A Distributed Denial of Service attack does need a group of infected computers to initiate the attack. Since these computers are spread out in many different locations this makes this type of attack more difficult to originate the source. All other types of attacks listed could originate from a single location.

This is the first thing that should be done if you suspect a computer is part of a botnet.

• Disconnect it from the network

• Run virus scans

• Run system updates

• Format the hard drive

These need to be updated or your anti-virus program is ineffective.

• signatures

• drivers

• passwords

• bookmarks

Answer explanation

Virus signatures are common blocks of code that help and anti-virus program detect viruses during scans. If your program does not have the latest versions it will be ineffective at detecting problems.
