I wanted to add my 2 cents to the discussion. The ads infuriate me. The menu bar offer to install Kaspersky is merely annoying. I've spoken to different persons in support, sales, and marketing at Parallels about it for over a year now. None of them seem to care and no one has ever offered to do anything about it. As a software vendor, if anyone in my company attempted this they would be immediately fired. I approve software purchases for my company's engineering organization. I recently vetoed a purchase order for a copy of Parallels for every developer in the company for exactly this reason. The only way to get Parallels to stop this is to show them they are losing money because of it. It's sad really as I like the Parallels software. Their engineers should be commended. It must be awful for them to know that every time the software starts and an ad pops up it just increases the level of disdain for an otherwise good product.
