I have an ASUS Laptop model Z81000 . After a relatively short period of use [10 min] the srolling function on the touch pad becomes unstable and you are unable to keep it in one place as it keeps jumping to the top of the page also when you are typing the cursor keeps retreating to the beginning of the message or whatever yu are trying to type. I enanled a mouse thru the usb port and this worked for a while but now is behaving the same as the touch pad. Suspecting a virus I ran AVG and Norton plus spywareprograms thru the computer but they have all come upm clean. Any suggestions?
