Your system was found to have the ATT Yahoo client software installed. The ATT/Yahoo software uses alot of system memory. Especially if you use their online protection software which is just rebranded inferior software made by a 3rd party company. System performance can be increased by removing the ATT/Yahoo software if you no longer use the ATT/Yahoo internet service. This software can be safely removed by using the <b>Add/Remove Programs</b> feature in the Windows Control Panel.
