IrcContact Backdoor

Removing IrcContact
Categories: Backdoor,RAT,DoS
Backdoors are the most dangerous type of Trojans and the most popular.
Backdoors open infected machines to external control via Internet.
Often the backdoor will not be visible in the log of active programs.
Many trojans and backdoors now have remote administration capabilities
allowing an individual to control the victim's computer.
Many times a file called the server must be opened on the victim's computer before
the trojan can have access to it.

These are generally sent through email, P2P file sharing software,
and in internet downloads. They are usually disguised as a legitimate program or file.
Many server files will display a fake error message when opened, to make it seem like it didn't open.
Some will also kill antivirus and firewall software.

Some RAT trojans are pranks that are most likely being controlled by a friend or enemy on
April Fool's day or a holiday. Prank RATS are generally not harmful, and won't log keystrokes or hack.
They usually do whimsical things like flip the screen upside-down, open the CD-ROM tray,
and swap mouse buttons. However, they can be quite hard to remove.
DoS programs attack web servers by sending numerous requests to the specified server,
often causing it to crash under an excessive volume of requests.
