i received a window on imac el capitan safari claiming my flash player was in need of updating. giving me a choice of yes, or no. since it rendered safari inoperable, (this and other types of scams i've had in the past), i clicked no, do not update. it downloaded a file in any case. i deleted it 2 times as it reappeared. now safari is inoperable. the update window is constant. i cannot open safari preference either, or delete history, etc. nothing. i have checked and my flash player is indeed up to date. i have searched online but cannot find any remedy. there was also something i tried copying text to 'terminal', indicating that my flash was trojan free, but noticed in cs6 flash player it indicated something was modified at the same date so possibly it altered that. wondering if there is a way of deleting certain files on safari, or reinstalling it without a full reinstall of osx. i have been targeted before with the genico malware and was able to delete it but this one i can't seem to find a remedy. thank you for any assistance.
