b> Laptops, especially models with a touchpad, occasionally experience issues with a skipping cursor. The cursor on the screen may skip or jump when you are using it or even when you are just typing and not actually using the cursor. This can be especially annoying when playing games or typing. Adjusting the sensitivity of your touchpad may remedy the problem.
Close all application windows and restart the laptop. This will shut down any background processes that might be affecting your cursor. Rebooting often remedies cursor skipping problems. Run antivirus software to confirm that your misbehaving cursor is not caused by malware. If the cursor has changed to an unfamiliar shape without you initiating the change, your system could be infected by a virus or you might have installed unstable software. Run an antivirus scan and remove suspicious files and programs from your laptop. Adjust your touchpad's settings. In Windows, open "Control Panel," click on "Mouse" and then click "Tapping." On a Mac, access "Trackpad" and "System Preferences." Lower the tracking speed or sensitivity so that if you are accidentally touching the touchpad while typing, you are less likely to cause the cursor to skip. Save your new settings. http://www.majorgeeks.com/Microsoft_Security_Essentials_for_Windows_d6242.html
