my OS X has been reinstalled, but the system still seems wierd

Is there anyone can tell me, why the mouse moves on the screen without me, and sometimes the dictionary on Mac starts to search something just by itself, without any demands, u can see from the picture below. and the screen moves from desktop1 to desktop2 without any mannual action, strange really!

It really makes me ****** off. Is there any virus? How can I solve this problem?.

There are several possible causes for this issue. Take each of the following steps until it's resolved.

1. Follow the instructions in this support article.

2. Boot in safe mode and test, preferably without launching any third-party applications. If you don't have the problem in safe mode, but it comes back when you reboot as usual, stop here and post your results. If you can't boot in safe mode, do the same. If you booted in safe mode and there was no change, go on to the next step.

3. Reset the System Management Controller.

4. If you're using a Bluetooth trackpad, investigate potential sources of interference, including USB 3 devices.

5. A swollen battery in a MacBook Pro or Air can impinge on the trackpad from below and cause erratic behavior. If you have trouble clicking the trackpad, this is likely the reason. The battery must be replaced.

6. There's a report that a (possibly defective) Thunderbolt Ethernet adapter can cause the built in trackpad of a MacBook to behave erratically. If you're using such an adapter, disconnect it and test.

7. There's also a report of erratic cursor movements caused by an external display that was connected but not turned on.

8. If none of the above applies, or if you have another reason to think your computer is being remotely controlled, remove it from the network by turning off Wi-Fi (or your Wi-Fi access point), disconnecting from a Bluetooth network link, and unplugging the Ethernet cable or USB modem, whichever is applicable. If the cursor movements stop at once, you should suspect an intrusion.

9. Make a "Genius" appointment at an Apple Store to have the machine tested.

Your Macbook Pro battery could be swelling making the Trackpad move.

To check the condition of your battery, hold down the option key and click on the battery icon in the menu bar.

If the condition is anything other than Normal, take your Mac to an Apple Store.
