Virus that enters Windows user account password automatically

Hi,
I have Windows 7 Home premium OS on my gateway laptop which has only one user account and on turning on laptop that user password gets entered Automatically which is unexpected and its very long. Then i have to hit enter which shows Wrong password message and then it allows me to enter my password, then entering this time my password windows get started.
one week before my PC got infected with few viruses and one of that was not letting me to type certain keys so I reinstalled windows 7 from scratch on my Gateway laptop with factory default settings to wipe out everything, Now I can use my Keyboard at full extent But on starting the PC still it.shows me that problem of unexpected password gets entered for user account and its very long to the limit of password length. I tried Norton antivirus & MalwareBytes premium trial versions, did full scan but it shows my system has no virus/malware. Please advise.

Though the previous virus/malware did make some keys inactive, on reinstalling OS from scratch with factory default setting, with all data wiped out, there doesn't seems to be any key stuck.

I added one more user account and now it doesn't enters that auto long dots password but my mouse pointer gets stuck...I have to press mouse pointer key to activate it...To make sure i restarted 2-3 times and every times mouse pointer gets stuck and I have to press that key again to start mouse pointer. Then again i deleted that second account and then again ghost of entering long dot password comes back for that single admin account.... my concern is that i have done re-installation of OS with no data backup, like new pc... but still on Admin user login screen it automatically enters the long password to full extent (.............................).

If you wiped the hard drive and reinstall the OS then don't think it's a virus or maleware. Are you able to remove laptop keyboard and use an external keyboard to see if password box gets filled up still
