    I have win 7 and Outlook 2013. I find that fairly often my system slows to a crawl. When I check Task Manager I find CPU is 100% even though I am doing virtually nothing. The main culprit seems to be Outlook. If I close Outlook the CPU usage drops down to around 10%
    My anti virus is Kaspersky Internet Security 2013
    Any adice greatly appreciated

    If Kaspersky is set to scan e-mails, try disabling that feature, as a test.

    Thank you Phantom010 Just a quick question. Would that not defeat the purpose of having an anti virus? Or am i misunderstanding?

    also, after Phantom's suggestion, you can start outlook in safe mode. start > run > outlook.exe /safe. That will run it without any add-ons.

    Thanks Valis. Are you saying I should always run it in safe mode or just to see if it helps?

    It's a temporary test to determine if Kaspersky is responsible for the high CPU usage. Furthermore, even if the e-mails aren't scanned, your antivirus will still stop threats as they're trying to infect your computer.

    You could try updating Kaspersky to the very latest version. Maybe it won't affect CPU usage?

    Or, you can ask their technical support for advice.
