I have just uninstalled an old Yahoo toolbar I had forgotten I had 'hidden' in IE 8. I actually updated it first, but decided it was pretty useless. As I was checking the add-ons manager in IE 8 (Vista HP) ~ Manage add-ons in 'All add-ons' mode & I noticed an add-on by SupportSoft Inc. called Symantec Script Runner Class version 6.9.26740 It appears to have been installed on April 9th, September 2007, which was before I actually bought the computer. It isn't a currently loaded add-on. I used to have Norton as my anti-virus program about a year ago but now I use McAfee NetProtect Plus which I get with my ISP (British Telecom). My computer is running fine & I have had no problems since uninstalling Norton, I just don't know what this add-on is or does. Any ideas?
