From the browser's settings menu or options, look for the add-ons section to disable or tweak some or remove them completely. Do you have a particular issue with your computer? Ccleaner is mainly use for clearing your temp. files and could also be helpful in removing programs, no other. If you want to disable startup programs which are not needed during booting, you can try MS autoruns or startup lite by Malwarebytes.
Well, I don't have much issue about my laptop, but it is old so I want to close some useless programs that I don't need because when I use the internet it starts to lag and when I check the Window task manager, I see a lot of program running so I thought maybe closing some of them would help.
Adobe didn't support Reader and Acrobat together on the Windows platform until both were at version X (10). There are reports of conflicts running the two previous to version X.
Just to clarify, it's bad to have Adobe Acrobat 7 pro with Adobe Reader X unless Adobe Acrobat is version X?
