And on top of all: MS Windows is the only systems I know of whose vendor
tells you, it is not safe to run without 3rd party software (antivirus).

Antivirus itself is fundamentally flawed idea: you can not enumerate bad.
You can enumerate good and prohibit everything else. So, antivirus is like
thinking backwards. (But given long record of MS in building poorly
architectured system, doing antivirus is sort of job security ;-)
