Keyboard not working properly (not a hardware issue)

Hi,
I use windows 8.1
Almost a month ago my friend had used my laptop to download a subtitle from ‘opensubtitles.com’ and I realized he happened to click on some pop-up links and the system was downloading something. Although I quickly aborted the operation, my browsers were severely affected and I had to uninstall Google Chrome and reinstall firefox several times to get it working correctly.
However I noticed that there was something strange with my keyboard- whenever I press a key two keys were pressed together-and backspace adds ‘]’ character. ( I noticed backspace doesn’t add this character while it is on the login screen- yet other keystrokes were same in the login screen as well)
After clearing several temporary files and folders I managed to get my keyboard working properly.
But that hasn’t solved my problem- every time I restart my computer my keyboard/keystrokes go back to same situation.
That it has become a necessity for me to run the ‘cleanmgr.exe’ on admin mode after restarting the computer to get the keyboard working correctly.
Can anyone suggest a solution for this recurring problem? I know that something is changed everytime I restart my system, and I know that the problem is ‘located’ in the temporary folders and files but I unable to locate the origin of the problem.
Any suggestions?
Thanks in advance.

Backup all your necessary files, then do a fresh installation of Windows OS. 9 times out of 10 those cleaning programs aren't effective
