Bug with Photo Website

Approximately 2 visitors believe there may be a virus/glitch on my photography website. ? I have had over 1,000 visits and no one has mentioned any problems. ? I visited my personal website yesterday and did notice an error message in the bottom left hand corner. ? I then opened the activity report which I will attach a screen shot to illustrate the error.? A friend told me that I just need to re-launch the site to fix this error which appears on all the web oages. ? Does anyone have any experience with this? ? Any help would be greatly appreciated!
