Finding strange files on my Macbook

I just turned on my macbook after it was shut down (for about an hour) and it opened up and Finder was open. Finder is not usually open when I turn on macbook. And inside it there was a weird file that immediately caught my attention, called isclientrunning.sh

Does anybody know what that is or why that would happen? Ive never even heard of a .sh file. Did I download a virus or have I been hacked or whats going on? It was just sitting there next to all my main folders.

Also recently whenever I browse random websites, or am on Firefox, sometimes a window always pops up asking me to open a file, called activity.php and things like that. It claims its from facebook.com, but am not on facebook. It is just weird because the window that opens is the same kind that pops up when I want to download an attachment from the internet or my email, as if I had already made a request to download something. But I just click cancel instead of open. It doesnt appear to be like a pop-up or anything like that. It has happened three times over the last few weeks

If anybody can help me figure out why there have been so many weird things happening, I would appreciate it. Thanks

 

thanks for the reply.

and no, as far as I know nobody has been on my laptop in the last few days. Im not sure what kind of a prank that would be though? Is stuff like that normal?

 

Yeah, sure thing. But if this is something that someone makes, then I don't understand how it wound up on my computer if nobody has been on it. Is it something I downloaded?

Also, when I look at the file info, it says it was created on March 16th. I feel like I definitely would have noticed it had it been there for almost an entire month.. I'm really confused.

#!/bin/sh
SERVICE='Statistics17'
CHECKFILE=~/.statistics_running
if [ -f ${CHECKFILE} ];
then
rm -f ${CHECKFILE}
fi
if ps ax | grep -v grep | grep $SERVICE > /dev/null
then
touch ${CHECKFILE}
fi
#!/bin/sh
SERVICE='Statistics17'
CHECKFILE=~/.statistics_running
if [ -f ${CHECKFILE} ];
then
rm -f ${CHECKFILE}
fi
if ps ax | grep -v grep | grep $SERVICE > /dev/null
then
touch ${CHECKFILE}
fi
#!/bin/sh
SERVICE='Statistics17'
CHECKFILE=~/.statistics_running
if [ -f ${CHECKFILE} ];
then
rm -f ${CHECKFILE}
fi
if ps ax | grep -v grep | grep $SERVICE > /dev/null
then
touch ${CHECKFILE}
fi

 

yeah, youre probably right. Strange. I'm probably just being paranoid I guess. lol But thanks for your help!

Anyway, Im sure this isnt related to that first thing, but any idea about the activity.php windows that open up? Im kind of curious to open one just to see what it is, but if it is a virus or something, I dont want to take that chance and I just always hit cancel and the window disappears.

 

Interesting, No I do not have that program installed. I guess its just weird that it just showed up all of a sudden.

So what does it mean to be getting those windows to open an activity.php . it says its from facebook.com but Im never on that site when it happens :s
