msMpEng.exe "Bob Darlington" <bob[ at ]notheredpcman.com.au> 10/31/2008 1:00:47 AM I'm running Windows XP Pro (SP3) with 3GB RAM , Intel Core2 2GHz CPU and Windows OneCare installed. Recently performance has slowed when running programs (esp MS Access with up to 25 seconds to open screens). This performance hit hasn't coincided with any program changes, except (perhaps) the change of OneCare from the trial to licensed version. I notice that MsMpEng.exe is running in Task Manager with memory usage between 50,000 and 69,000 K. I understand that this is related to Windows Defender, but can find no trace of that program on my PC. If I turn off the Virus and Spyware option in OneCare, MsMpEng remains (but at a slightly reduced Mem Usage of 45000), but Access performance improves. Am I right in assuming that if I have OneCare enabled with Virus and Spyware, then I shouldn't need Defender? Is MsMpEng part of Defender AND OneCare? How can I stop OneCare slowing down my Access programs? -- Bob Darlington Brisbane -- Bob Darlington Brisbane

Any ideas as to why OneCare should be slowing down an MSAccess application? -- Bob Darlington Brisbane "StephenB" <sboots[ at ]mvps.org> wrote in message news:vookg4losa6j8ka8dk4cm057u4j65qg1dm[ at ]4ax.com...

I'll try excluding that folder and see what happens. -- Bob Darlington Brisbane "StephenB" <sboots[ at ]mvps.org> wrote in message news:b4hlg4l8ep3ka39jtnid0bafqqamg1tj1p[ at ]4ax.com...
