Do I have a computer virus?

My SD card slot has been giving me trouble.

I would insert the card and it would not register, the green light beside it would not illuminate and Drive H was not even listed in my computer.

Then today I tried it again.

I inserted the card, and the green light started blinking, my computer then brought up my Webshots desktop, (drive H was recognized) and a video that said “Suicide Close up” which was short and blurry.

I saw the title and I closed the window (before investigating further) because I didn’t want to see anything like that.

I Googled these symptoms and came up with a link for the Conflicker virus (which didn’t seem to be related to anything I’ve experienced with this.)

I am scanning for viruses now, but it has not brought up anything. Does my PC have a virus?
