Trojan Virus known simply as "Security Suite"

A few days ago, my laptop was infected with "Security Suite."  Norton Int Sec did not catch it and could not find it during a thorough scan.  The virus would not let me access the internet except to go to their site to purchase a "solution" to the problem.  It would not let me use System Restore.  I had to use the recovery CDs and start all over from scratch.  Had a a similar occurence last Oct when a different computer was hit by "Cyber Security;" however, it did not block my access to the internet and I was able to kill it through StopZilla.  Anyone else experience these problems?
