Thank You for taking the time to read my post! :o)
I am 83 years old and have recently moved into a Senior Citizen (Community) home, hence prior too I had to engage in a great deal of downsizing & belt-tightning...
I saved some money (short term), yet also had to put up with trade-offs...
For one, there is only ONE ISP provider for the entire building (basic cable) and all of us share the Wi-Fi which slows down internet speed (obvious when watching streaming movies which stall/refresh dozens of times).
So, a few days ago I noticed that my curser was vibrating (shacking) and gradually slid down half an inch from where I had left it on screen (external, Samsung, compact mouse). I thought I had merely imagined my curser shacking, yet today I found out the hard way that was not the case.
Someone has partial control of my HP laptop...I had "parked" the curser...when someone else moved it...used it to rapidly open/close webpages in front of my eyes.
I could not close my laptop via startup/task bar, hence I had to hold down the power button for 20 seconds.
I cleared ALL browser data/made sure cyber security extensions were "ON" in Google Chrome web browser.
I ran MBAM Premium clean results (0 threats).
I ran ALL Norton scans clean results (0 threats). I also used Norton Power Eraser.
I restarted the HP laptop hoping that had done the trick...sadly NO...when I tried to check Norton History/Firewall...the curser was taken away from me (someone else browsing up & down history...even clicking on an Activity...TO GIVE ME THE MIDDLE FINGER!). :o(
What I have noticed...at startup...suddenly there are 3 phantom pages there/rapidly disappear. I can see the top bar (black) of the page & the sides, yet the inside is blank/invisible...then the next page...and then page number 3 (all I can make out...top of page/black bar win32 "something"...it happens very fast).
I have done ALL I can/know of, hence I was hoping for some good advice from the good people on these forums.
I THAK YOU for having taken the time to read my post any useful input/solution is gladly welcomed! :o)
