I use it every once in awhile , But I only use the Kaspersky antivirus online scanner , it will detect & remove certain viruses that others wont & wont remove some that others will .
If you download & run the online scanner its no more dificult to uninstall then any other , however if you purchase it & install it its much like norton & hard to remove all of it but posible . At least thats been my experience . I run Avast as well full time .
