Letter from Virgin

Just received a letter from Virgin Media to inform me that my "Financial Transactions and Personal Data could be at risk" as my email address has been sending out a high number of SPAM emails Reading down the letter it tells you how to fix the issue and then at the end it says you can get a programme called F-SURE SAFE which is free (for 12 months) and then £25.00 a year after that. Has anyone else had one of these I presume it is just a ploy for people to sign up to this F-Secure programme?
