How do I avoid downloading toolbars/add-ons?
Many toolbars and add-ons can be avoided by opting out of extra software included in a program’s installation. Read each dialog box carefully and uncheck any extra install box options.
Using strong antivirus software and safe internet browsing practices will also protect your computer against these annoying downloads. Running regular antivirus scans will alert you of downloaded toolbars and add-ons which are potentially harmful, and give you the option to remove them.
