Ad by Jak Won't Leave Me Alone! What's Going on Actually?
Ad by Jak is an unwanted advertising platform that has depressed lots of computer users recently. Jak adware presenting itself as an innocuous plug-in/extension on browser can penetrate systems via the distribution of a third party (such as shareware, bundled program or unwanted browser toolbar etc). Someone affected grumbles that "this virus" keeps harassing pop-ups on whatever page he/she goes to, and the ads also appear in google search results.
