Virus/Malware Reports - Please post here

I know this is an older thread, and my problem is not exactly a virus, but I don't know where to put it.

When I log on on my husband's laptop (running Firefox with Ad-Block) everything is fine.
When I log on on my Wii (because my computer is dead) I get random pop-ups saying that "such & such site has an invalid security certificate". I'm fairly sure it's related to one of the ads, but I'm not sure which one. I don't remember off the top of my head WHICH site it says... And it only happens at random times. The Wii runs a mini version of Opera I think...

I'm gonna keep an eye on it and try to write it down next time it happens... I can't do a screenshot on the Wii.
