Constant Scrolling Through Selection Options - Requires Shutdown

[jmet2004]

I'm using an HP Pavilion dm4 laptop running Windows 7 x64 plugged into a monitor, keyboard and mouse. This problem has happened three times today, all while I have several programs open and ultimately requires me to force a shutdown.

In whatever program I have open, the selection options highlight in sequence at a rapid pace.
- In Firefox this means it looks like I am hovering over the minimize, then the maximize, then the exit button, each for a tiny fraction of a second... but it doesn't stop. It just keeps highlighting the buttons in that order until I close the window - which takes several clicks to coordinate with the "phantom" selection.
- In Excel, if I have a cell selected, it looks like I am holding the right arrow, and selects the cell to the right->right->right->right... until I'm in column ZZZZZZZZ. If I try and close excel and it prompts me to save a file, the pop up window "phantom scrolls" through the options Yes, No, Cancel and the exit button at the same rapid pace. It takes multiple clicks on a selection for it to work.

I've tried unplugging both my keyboard and mouse when this happens and there is no change. I'm afraid it might be a virus. I've run a full system scan using AVG 2012 and no issues were flagged.

Download, install, and update malwarebytes and do not start the free trial. Run a full scan on your system. Post back your logs. I will ask that this be moved to our system security forum.

Correct me if I'm wrong, but the keyboard on the laptop still works when you plug in another to a USB slot. Right? I mean, that's the way it works with my boss's Compaq. I'm thinking you have a sticky button on the laptop keyboard.

Good call PeaB4YouGo.

jmet2004,
I would check if the right arrow key is stuck on the laptop keyboard first.

Right Key Works

I've connected the keyboard to several USB ports and they all work fine. I've checked the right key on both the keyboard and the laptop and both are functioning fine with no stickiness. When this issue happens, I have rarely touched the right arrow key (maybe an hour or so earlier). Running the malwarebytes now - will post update when scan is complete.

This was a solution to a similar post some 4 months ago... I was hoping lightning might strike twice. LOL
