I have similar case as in this
I have 2 windows 7 on different partitions .. worked for 3 years.. but for a long time I used to use one having avast antivirus
Recently I installed a software then i discovered it contains a maleware "ads by cinema-p" then "ads by name" .. I couldn't remove it by any antivirus or tool .. but I just deleted any existance of it from data files or registery .. and reinstalled browsers
Afterwords windows started to hang till it stoppedI just returned back to the other old windows 7 system .. i installed microsoft antivirus (i don't remember name) but it didn't find any viruses .. but system started to hang as well .. I tried installing bitdefender 2016 i couldn't complete installing as the page of registering became all white .. I installed panda antivirus but it didn't complete scanning .. sometimes i saw it turnes deactivate so i activate it then it deactivate again .. which seems as a virus preventing ..I reinstalled windows but the 1st message was that I have a hard disk fail and i have to back up my dataI'm trying copying important data but system is hanging often .. system repair says also I have a hard disk proplem
Now windows is crashed & i'm going to reinstall it again .. as i can't access even the safe mode anymore
Pleasr advice .. thanks on advance
