Lately I have noticed a lag between mouse movement and response the same as I would have when I used to use Log Me In and working remotely to this computer, but I am directly on it. I do use CursorFX to change my mouse pointer, but have done so for more than ten years. As my kids use this computer also, I am concerned that they unknowingly did something (Not to say I am not above doing something stupid). I have run Spybot besides my constant running of the Microsoft utilities - Defender and their firewall enhanced by Windows Firewall Control, and yesterday ran the Kaspersky Virus Removal Tool, which all found nothing wrong. I do not know what to do next. Normally I would start throwing everything against the wall, then finally wiping the disk clean and rebuilding, but even that could have something tag along with documents and family pictures I would save. Would someone out there that actually knows what they are doing (in contrast to me...) please suggest intelligent steps to now follow? Many thanks. - Just un-nerving to know someone out there is likely watching everything I am doing...
First I would remove CursorFX and any other software that might affect mouse movement. If that wouldn't help I would scan my system with some other on demand scanners: Malwarebytes AM, Emsisoft Emergency Kit and Avira PC Cleaner to name few.
