Sophos Anti-Virus can detect members of the VBS/Haptime family generically as VBS/Haptime-Fam.
VBS/Haptime is a worm that spreads via Outlook Express version 5.0. It attempts to infect files with the extensions VBS, HTML, HTM, HTT and ASP. Most members of the VBS/Haptime family will also attempt to delete EXE and DLL files when the month plus the day are equal to 13 (for instance, June the 7th).
