Virus fra Microsoft?

Hej.

Jeg får hele tiden mail fra "Microsoft" med en vedhæftet exe-fil, som angiveligt skulle være en q-artikel-opdatering. Så vidt jeg ved har Microsoft aldrig udsendt exe-filer til opdatering og adresse, IP og Return-Path er dog også langt forskellige fra MS. Pt. læser jeg kun post i webmail. Men hvad kan jeg gøre? Jeg læser post et sted, hvor det ikke er forsvarligt at hive den ind i et beskyttet post-program og lade antivirussen identificere den. Så jeg aner ikke hvad det er.

Følgende tekst i mailen:
============================

Det ser jo overbevisende ud, men:

-----------------------------------------------
Warning !!! The attachment's filename has been changed!
-----------------------------------------------
Anti-Virus Scanner of Wirtualna Polska mail system has changed
the name of attachment, which can contain a virus. The last dot
character in its filename has been changed to underscore, in order
to avoid automatic execution of the attachment included in the mail
message.


Kan nogen identificere denne virus? Og kan jeg gøre andet en at skifte mail-adresse for at slippe af med den?

Med venlig hilsen
Per

PS: Vedhæftet til mailen er som regel en exe-fil (de seneste er dog omdøbt), som hedder q######.exe, hvor # er et ciffer. Artiklerne findes sjovt nok IKKE hos Microsoft :)
