Hi, just wondering if anybody is familiar withe the above, I'm running Win7 on a compaq laptop and when I run a virus scan the machine is clean but when I run a rootkit scan I get ZwYieldExecution+ox10f3ntkrnlpa.exe. AVG says it is now secure after I press 'resolve all' but immediately after I run rootkit again, I get the same result. I ran it 24 hours after the initial scan with a re-boot to find the same result which is why I ran it twice today?
