SG Browser Hijacking Protection is a part of SpywareBlaster and SpywareGuard (sgmain.exe) which are mostly free utilities that enable users to automatically block undesirables from effecting the computer. If set to automatically update, a small annual charge will be incurred, also some users/groups do not qualify for free use. SpywareBlaster may disable, not remove, some pre-existing spyware applications but its purpose is to protect the computer from Active-X based installation of undesirables, block tracking cookies, and control available actions of specified (potentially undesirable) web sites.
