This is indeed a virus program specifically written to block the browsing to certain sites.
I would like to mention here that any online transaction, made on other than direct bank sites are not advisable as the system files are infected.
Please see the address bar when you type the URL of your bank site, you will be able to see "https://www.banksite.com " rather than " http://www.banksite.com". Please make sure that you access your bank site if you see https in the beginning of the site rather than http. You should also check verisign symbol and lock symbol prior to proceeding any money related transaction.
Above checks will ensure you that your transactions are safe.
