These "tracking cookie" or "phone home" viruses are getting more and more complex. Sometimes, I can Google to find answers.
Sometimes I'll visit BleepingComputers and they'll provide a good solution.
But more often, I'll find a variety of answers and most won't solve the problem. I have to keep searching and trying.
This is an exercise in YOUR patience, therefore.
I'm facing one of those DoSearch type plagues on a shop-neighbor's computer. This user continually visits unsafe websites and, while I've got 30 other shop-neighbors, this ONE user is always the one with the worst experiences. And the worst user-discipline.
And this latest proves that this uncareful, lazy user-discipline creates a foe that defeats any fix-it tactic I've found so far. What's left? "Complete wipe-out and re-load - a 20 hour job." A very long, dull, "press ENTER a kajillion times" process. Yawn.
My chosen solution is "Leave it. Let them enjoy their hijacked computer. Maybe THEN they can finally understand the frustration of THEIR lack of discipline."
None of this helps you at this time. Rapping your knuckles here won't, I realize.
But perhaps it can help you in the future by knowing your computer was probably infected by an installation of downloaded freebie software. And after downloading it, the installation choice was probably "express" or "recommended" or "automated" - the laziest and worst choice of all.
Instead, using the Custom Installation choice will be superior, but it takes careful reading for each screen, and paying attention to every checkbox. Even then, there's no guarantee these hijacker phone-home tracking-cookie viruses won't be installed. No matter how much I rail against a user's lack of discipline, I believe these hijacker viruses will find a way to install themselves even on the most careful user's computer.
That's what they live for.
(Any time you need an unsympathetic boot, let me know! ha ha... just know I've been there/done that, and all of my grousing is sharpened by personal experience! Eventually, I know I'll end up doing a Wipe-Out-ReLoad on that user's computer. I have to do it every 6 or 10 months anyway, because eventually, the nags and whines will wear me down. grrrr... but that's what shop-neighbors are for.)
