I'm sorry to report that my computer was infected
with a mass-mailing worm program called W32.Navidad, which replied to
every inbox message with an attachment and replaced it with a copy of
itself (you may have seen an eye icon or "navidad.exe"). Hence the
proliferation of old messages and virus warnings. If you were unfortunate enough
to open the attachment, you can download a repair command from www.symantec.com/avcenter/venc/data/w32.navidad.fix.html.
Sorry to clog up your email and waste your
time. I hope any damage done is minimal and reparable. I repaired my
own computer as soon as I could figure out how.
The lesson here? Be wary of ever opening an
attachment, especially one with an .exe extension. Many, many apologies for your
