I uninstalled WeatherChannel for Desktop, which was taking 30,000 K. Hopefully, that will help. Firefox is taking 552,000+, but I assume that's normal. Other items are much smaller.
My OS is Windows 7. Not only is web browsing slow, but even when in documents such as Word and Xcel. It also takes a long time to close tabs in my browser.
Maybe clearing the cookies and ininstalling WeatherChannel will help. Thanks!
