Shortly after the Oscar winner's death last month, a photo of a strangulation victim who resembled the star was lifted from a Spanish-language website and posted online, with the sick pranksters alleging it was the final image of the actor.

Zelda, 25, urged fans not to open a link leading to the fake photo, and later announced she would be taking a break from social media to properly grieve her beloved father.

However, on Monday, nearly three weeks after logging off the microblogging site, Zelda returned with a simple post that read, "Thank you."

She also attached a link to her personal Tumblr blog, which features a quote by Williams' "Mrs. Doubtfire" co-star Harvey Fierstein, who said, "Never be bullied into silence. Never allow yourself to be made a victim. Accept no ones definition of your life; define yourself."
