Brief Description

Widow.5741 prevents access from programs to websites of several companies related with security tools (antivirus programs, firewalls, etc.).

Widow.5741 redirects attempts to access several web pages to a specific IP address.

 

Widow.5741 does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc.

 

Widow.5741 uses the following infection strategies:

  • Encrypted: it encrypts its code in order to make it difficult to detect. In order to carry out its infection, the virus decrypts itself and, once infection has been carried out, it encrypts itself again.
