I googled Parallels Desktop earlier today to read up on it, I'd never heard of it prior! I eventually decided "Boot Camp" would be the way to go, so never bothered downloading the trial, but since then, when I've been browsing other sites a Parallel Banner Ad keeps popping up. Now I expect Ads on most websites, they generate revenue and I don't usually have an issue with them, but I don't like being targeted specifically! it makes me jumpy about what else might be stalking me. So would this be Google or Safari doing the tracking, and how do I find out which? I would instantly sort this in windows, but I'm new to Macs and haven't got a scooby doo (clue) how security works, so any advice on how I can prevent this happening again (cookies, browser setting adjustments, etc.) would be appreciated. Thanks.
