Pls advice as since my last update by mcafee i am getting this error " mcagent.exe - Application Error. The application was unable to start correctly (0xc000009a). Click OK to close the application." I am using Mcafee Anti Virus Plus since november 2011. My laptop is Lenovo G460 with windows 7 and core i3. Though i can access net and also other applications on the laptop are working properly as usual.
Try running the Virtual Technician to see if it will fix whatever it is: http://mvt.mcafee.com/
If not then try a complete uninstall via Control Panel > Programs > Uninstall a Program
Run the MCPR cleanup tool listed under Useful Links at the top of the page and reboot.
Install the software again from your online account.
If it happens again I would contact Technical Support - it's a free phone call or online chat and also linked under Useful Links.
Last thought, if you are using registry cleaners/optimizers, don't. This is the sort of thing they cause.
Glad you are OK. Have a good weekend. ;-)
