I am currently having a bit of a nightmare with my phone/tv/internet provider...they have charged me nearlly 200 quid for premiun rate calls which i definately have not made...what can i do????
you can get BT to block premium rate calls 090 free of chage and for a quarterly chage they will block international calls.
quick fix: unplug you computer from the telephone line when you are not using the net.
its almost certainly a dialer do the following two steps
install/update your antivirus and do a full system scan.
Install Spybot search and destroy (google for spybot) update it and scan your pc with this as well - this will remove a lot of spyware and probably speed up your machine as well.
some shareware software needs its spyware to run correctly if after running spybot you find something is not working and you are sure you really need it just reinstall it
in regards to the above question there is not very much that can be done. as advised in some of the above answers all you can do is get bt to put a premium rate call barring, which is free and does work on the 090 numbers. then you needs to contact icstis who is the governing body of the premium rate calls, to get these looked into.
