This is, in fact, quite a destructive virus. As InFinRetirement says, it sends mail to all of your contacts via Outlook. It composes a message using random words taken from .txt or .doc files on your PC and then searches for a .scr or .exe file of less than 128KB to infect and attach to the e-mail, so the attachment may vary as the e-mail is passed on.
The following is a brief extract of the virus description, with acknowledgement to Symantec. The full text can be found at

"If the computer has been infected for one month and at least 100 people have been sent an infected file, and if at least three files contain at least three examples from the following list:
sentences you
sentences him to
sentence you to
ordered to prison
convict
, judge
circuit judge
trial judge
found guilty
find him guilty
etc
then the virus will activate the first of its payloads which does the following:
Deletes the infected file
Erases CMOS (Windows 9x/Me only)
Erases the Flash BIOS (Windows 9x/Me only)
Overwrites every 25th file with the text YOUARE!!!! as many times as it will fit in the file
Deletes every other file
Overwrites a sector of the first hard disk
This payload is repeated infinitely."
