Norton AntiVirus
Norton AntiVirus does not like ratrabbit.nl
When I publicised my tennis-scheduler, one of my tennis mates wanted to use it, but had to tell me that Norton AntiVirus procuced a large warning window with red background, stating that ratrabbit.nl is potentially unsafe to use.
Of course, I did not recommend to ignore that warning, after all she did not pay for the antivirus software to ignore it's recommendations.
BTW: Other antivirus software do not warn against usage of ratrabbit.nl.
I tried to convince Norton that ratrabbit.nl is safe
I went to the website safeweb, filled in the url ratrabbit.nl and the form and waited a week without getting a response.
So, I filled the form again, but on submission, I got the message that the "dispute" was already going on.
Still, ratrabbit.nl is "unsafe" for Norton AntiVirus users.
Conclusion
I understand that false positives are inevitable sometimes, but it is a pity that a well-known antivirus software supplier does not react to forms filled in on a page that specifically is designed to give feed-back.
The reason why Norton AntiVirus thinks that ratrabbit.nl is unsafe is a mystery to me.
Other websites will suffer from the same problem, so users will tend to ignore the warning from Norton AntiVirus, thereby exposing themselves to some risk.
