If the user runs the attachment and Outlook is installed, then W32/Caric-A sends itself to the addresses in the user's address book. The worm also displays a cartoon of a man wearing a "Bill" badge and playing a saxophone.

The worm saves a copy of itself in the Windows system folder and adds the following value to the registry:

HKEY_CURRENT_USER\Software\Microsoft\Windows\
CurrentVersion\Run\win = "C:\Windows\System\cari.scr"

W32/Caric-A has a payload which is activated at 8am every day. It attempts to delete C:\*.*, D:\*.*, E:\*.* and F:\*.*. It will also try to remove files with the extensions SYS, VXD, OCX and NLS.
