Dell upgraded my system from Windows 7 to Windows 8.1before I purchased it: Now "tweakBIOsdriverfirmware "ChipsetIntelMgt.EngineInterfaceDriver is "incompatible and won't install.
2. I failed to turn the Firewall off, disable 3rd party apps, and pop up blockers, and McAfee malfunctioned when I restored computer to earlier state.
3. McAfee then used remote access to install and run MCPR tool to uninstall & reinstall it. Now I have duplicate McAfee icons running simultaneously in the TASK MANAGER: (2x) McAfee Core Firewall, (2x) Vulnerability Scanner, (2x)Process Validation, WMI Provider Host (3x), etc. They said to contact a tech. It's a OS configuration issue, not McAfee.
Q & A: How to end the duplicate tasks running processes. Will it turn back on reboot or crash? Is this an issue for Dell (Inspiron 3847)? 4. I can't restore to factory state w/ (W-7), because my System Recover Disk is for W-8.1. Any thoughts would be greatly appreciated. Sincerely, Kathie.
