not trying to get into a pissing contest, but you only get that message when some external program is trying to access the IB system on your computer. Look at what the question asks : Do you want to accept an INCOMING connection, not do you want to connect with an external source, in this case you mean the IB servers.
And if it not a program you are running, then something you are unaware of is trying to access your TWS on your computer.

I see! Thanks for your help.The only program I can think of is Avira anti-virus,could it be that?

It is not Avira, as I run Avira and TWS with no problem.
As ctsfx said "you have an external program trying to access IB's API functionality". If you don't know what software is running on your computer you need to bring up the task manager and verify every process running until you find the problem software.
