Hello and welcome to justanswer. My name is***** will be assisting you today. I am sorry to hear that you are having such trouble. I will try my best to help you.
Are you using the touch pad on the laptop or USB external mouse ?
Does this happens when you are not doing anything like watching a video ?
Did you check it ?
One possibility this happens is when your palm accidentally touches touch-pad area when you type and that has the multi functions like Zoom etc so if your palm touches it accidentally this can happen ,The best method to check this is to connect a USB mouse and then disable touch pad and use the USB mouse.In this way you can make sure whether it was your palm touching the touch pad and causing it or not.
Do you have a USB mouse with you to check this ?
If its happening randomly then the above mentioned case can be the issue.Have you tried a USB mouse to check it before?
Also which antivirus scan did you ran to check for viruses?
I was not suggesting you to switch to USB mouse i suggested the above to check whether it that's all.
If this issue is happening while your hands are away from the keyboard and touch pad then the above mentioned is not the case.
We can run a virus/malware scan using another program called malwarebytes anti-malware and see if there is any threats.
Please click on this http://www.malwarebytes.org/ then click on download. Install and update it then run a Threat scan. If it finds any threats select remove all. If it asks to restart please do so.
After the restart please check it and let me know the result.
I am not sending you any text our only conversation is using this page.
You do not need to purchase malwarebytes anti-malware you can use the free version to manually run the threat scan and remove the threats.
Also see if there is any adwares in the PC which you can check it and remove using this https://toolslib.net/downloads/finish/1/ download and click on scan, once scan is finish click on clean. Then it will ask you to restart please do so.
Please do let me know the result all of this.
Thank you.You can also reduce the sensitivity of the touch-pad which you can do it from the touch-pad settings in mouse settings in control panel.
Good then let the scans finish and see if it finds any threat,if so remove it also run the adware scan too and remove the threats.
There is a possibility for it and that is why i am checking it + anti-viruses are not good in detecting malwares and adwares that is why i gave the above programs to check it.If that is also not the cause then we can try re-installing the driver for touch-pad.
The adware scan is given in the second link if you are not seeing i will resend it
Here it is https://toolslib.net/downloads/finish/1/
It removes the infecting kind of PUP and keep the others quarantined.you do not need to buy it now,lets see how all these goes and if its does fix it then consider purchasing.
Good and then check it and let me know the result.
Glad to know that.I suggest you keep on checking for a day and then let me know.

For the time being do not do that lets check it for a day.
If its happening again then remove the driver from programs and features list which you can access it by right clicking on start menu.If its not listed in it then you only need to download it and install it.
There is no specific driver for the windows 10 but i believe the windows 7 version of the driver will work which you can download using this link : - http://support.toshiba.com/support/modelHome?freeText=1200009406&osId=31 i believe your PC has windows 10 64 bit,if not let me know.
Please do let me know the result after a day.
Sir its been more than a day.How are things going on regarding the cursor issue?
have you tried installing the touch pad driver?
Try installing it and see if that makes any changes,if not then it can be due to some contact issue on the flat ribbon cable or even a faulty cable which need to be checked in detail by opening the laptop.
Thank you for the update.
