Last icon of desktop always selected

[AdityaKumar05]

When I start my computer last icon of the desktop is automatically selected.
When i click on other icons only the last icon is opened.
I can open the icons if i press the ARROW or WIN button and refresh.
Initially it was only at startup but now it comes again and again i.e. If am using file explorer,Last folder of drive is automatically selected,if i am in any subfolder last file or folder is automatically selected.
Things i have tried to solve without success-I formatted my C drive and again installed new OS but no success.I also run boot time scan with antivirus,By Rescue disk(Kaspersky) but no virus found.
Please help me.

Sounds like a hardware issue either with the keyboard or touchpad. If it was a virus or software issue a clean Windows setup would have taken care of it.
