Defender should most definitely be off in Windows 8 when you have a 3rd party antivirus such as McAfee installed as running 2 antivirus application could cause security problems.
What does McAfee SecurityCenter say, are both firewall and antivirus turned on?
By the way you say you restarted the laptop. In Windows 8 if Fast Startup is turned on the OS in fact doesn't reboot, it simply goes to sleep and wakes up again which is bad if a major update has occurred.
You can turn that off here: http://www.eightforums.com/tutorials/6320-fast-startup-turn-off-windows-8-a.html ?ltr=F
If there's a problem try running the Virtual Technician once or twice to see if it fixes things: http://mvt.mcafee.com/
mcafee security center says that firewall and antivirus is on. i've tried to turn windows defender off in the task manager but it doesn't work. also before windows defender was always off when mcafee was running.
i'll try the methods that you've shown me. thank you
thanks your advice helped me alot and the problem is fixed. but i have 2 questions that doesn't have to do with the topic
1. Is the "mcods" (mcafee scanner) something essential for mcafee to work?
2. i've installed mcafee virtual technician when i've first used it, it went fine and fixed my problems. i closed it then i wanted to re-open it but it seems that i can't and i don't know why. the program icon is just a white file and when i click on it it doesn't open mvt so i'm wondering if this is a problem or not
thanks in advance
1. mcods.exe is the McAfee On Demand Scan and is essential to keeping your system safe so don't alter it or disable it in any way.
2. There are two ways of dealing with this. a) Uninstall McAfee Virtual Technician from the Program list http://www.sevenforums.com/tutorials/77761-programs-features-uninstall-change-pr ogram.html
or..b) reinstall it and it should detect the previous install and up date it and make the icon active http://mvt.mcafee.com/ - then you can choose to keep it for future use or uninstall it as above.
thanks for anwsering my first question and for the second one i uninstalled it and reinstalled it and the program icon hasn't changed and i found out that for mvt to work anytime you have to go to "services.mcafee.com" plus yesterday when i ran mvt it only found 2 problems but when i tried it again this morning it found 13 problems in the registry. is it because of a virus that myy registry is weird or maybe it's because i ran ccleaner and it deleted some of the mcafee files?
Don't alter the settings of services.msc, obviously you or maybe an infection have and now things aren't working properly, plus the software wont work as expected if you remove parts of it, why would you even try to do that? You will most likely have to uninstall, cleanup using MCPR, reboot and reinstall.
Are you using CCleaner as a registry cleaner? If so stop as it's work is NOT reversible.
You may also have to end up doing a repair installation of the entire operating system, which is beyoned the scope oi these forums. Technical Support may be able to assist you and avoif that but I can't guarantee that.
OK, but I wondered why you needed to go to services for MVT, seems rather weird, unless maybe you are using a user account that is standard rather than adminstrator-level?
