Windows Defender and McAfee Security conflict?
Some months ago My HP laptop suddenly made a plaintive squeak and died or so I thought. I realised there was a strange glow from the now blank screen. Eventually I turned it off after trying to restart it,then started my quest for information as to what had happened. Nearly everyone I spoke to concluded the graphics card had died even, an HP technician on the helpline.When I was told the repair could cost £200 I became depressed and stuffed the laptop in a case hiding it in a corner and going back to the old steam driven time machine embarked on another adventure. But that is a different story.
Recently I sent the laptop to the workshop of the brother of one of my friends in a vain hope of help. When it came back I took it out of the case blew all the dust out of every cavity I could open and switched on, not really expecting anything but the backlit blank screen. Miracles the machine started normally. How clever of me I thought and bragged to all my friends how I had cured the ill machine. A scan started automatically. Nothing was found. When discussing the problem, the following day, with my friend she mentioned security conflicts can cause problems. At this time Windows Defender had brought up a security alert, I investigated and found the virus detector was invalid. Funny I thought so is the McAfee one. Still I will run the scans that it can do. Wrong Move. while it was doing this a McAfee warning came up just at the point where I had to leave the room to deal with someone who had called. by the time I got back the screen had died again!
The problem seems to have been caused by a Windows update which happens automatically. The update could not download the day before because I had changed my BT. home hub and the laptop had not been reconfigured and tuned in. Now the REAL question is do I have to wait for months again for the problem to resolve or is there a magic formula that I inadvertently used while cleaning the keys that got the machine to start up normally. I have tried pressing Fn+F4 and everything else that I could think of that might help. Maybe you have the answer. Anyway the one thing I have done is to switch of the wireless connectivity so the problem cannot recur but have I done the right thing there would the problem have righted itself while the machine was switched off or possibly while plugged in at the workshop it went to when another update might have downloaded automatically the machine then switching itself off as programmed to when not used for a certain time?
