My post of two weeks ago has received no replies for about 10 days now, so lets start over. I'm running Windows 7 in a Dell Optiplex 320. It is slow and I get a lot of "Not responding" messages. My antivirus is Avast; I run Spybot S&D, Malwarebytes, Superantispyware, and McAfee Stinger as on-demand programs fairly frequently. I use CCleaner. It is still slow etc. So I would like Bleeping Computer to take a look at it. You guys have always been good in the past.
