have i done a stupid thing

[mandimoo]

found a bargain norton 360 2 year subscription for £20. phoned the number, gave the credit card details. they sent me an email with a link in it. i had to run the norton removal tool to remove norton internet security, download a download manager (?), then install norton 360. when it asked for the product key, i had to phone them again and they gave it me over the phone and i activated norton there and then. thing is, i never wrote the product key down and when i asked them to confirm it by email they said it was a one off activation and if i have any trouble with it i am to phone them. the company seems to be selling on ebay with lots and lots of very positive feedback, but have i been stupid? im very concerned i could be being keylogged but dont know if im being paranoid in my ignorance. the company are select it solutions uk

Check with the Credit card Co to see if it's not being misused.
I dont know if this would help but I would remove the Norton program{it means you loose your £20}.
Also remove it from your files & folders. go to START>SEARCH>for files and folders>all files and folders>more advanced options{tick top 3 boxes}>search. Delete all results.
Install Free Microsoft Securities . Google it
