How to remove Web Bar

Using NIS 2014. Web Bar malware or whatever has been installed on system. Instructions to remove just say to go to control panel and uninstall which doesn’t work. Says " unins000.dat" does not exist and can’t uninstall. Went to Users/local /app data folder which I had to unhide and can see Web Bar folder there with a file named unins000 but clicking on it doesn’t work (this maybe an exe extension and not dat extension). Not much inf on th Internet on how to fix this. Anyone got an idea.
