I've had this problem 3 times consecutively trying to restore my system after it was destroyed by what seems to be a virus. It took that many tries before I realized the in-your-face advertisement and problem process are coming from Adobe itself.
THE PROBLEM
The apparently viral process runs as SVCHOST and uses the RasMan (remote access manager) service, apparently to transmit the contents of your hard drive to someone across the internet. It takes 99% of CPU, 1/2 Gig of memory, a lot of disk activity, and high transmit volume with low receive volume over the network. Unplug the network, and the SVCHOST falls to about 35% CPU with more intermittent disk activity. Plug the network back in, and it climbs back to 99% with high disk activity, and high transmit volume. It seems clear that it's copying the hard drive out to the network. Before I realized that, I thought it might be an internal process and just let it run to get it over with. It just got worse, finally running the machine out of memory and making it almost too slow to terminate the SVCHOST. When I finally did terminate it, the machine returned to normal.
WHY I THINK IT COMES FROM ADOBE
I restored my system to a known clean state from a disk image. I've done that 5 times now. The first thing I do on booting the restored system is wait and check for that process -- it's not there. Next, I update Firefox, then wait again. No problem, as long as you don't click on the Update Flash Player link. Then you click on that link, and immediately there's a pop-up and it plays audio saying "You've won a free Xbox", or else some other advertisement -- it's not always the same -- and also opens a tab to a site outside of both Firefox and Adobe. Some advertising site. So, I first thought I'd been spoofed by a false advertisement and unwittingly clicked on a malicious ad banner. Restored the system again, and next time went directly to Adobe. Clicked the link to download Flash Player, and... immediately, a similar ad popup and tab appeared, and it played a "congratulations! .... you've won ____" audio clip.
Right after each incident where the ad appeared, the computer began bogging down with disk activity and high CPU consumption by that SVCHOST process, and apparently copying out the hard drive to the internet (high network transmit activity).
IT'S NOT THE PLAYER ITSELF
I never even got around to downloading and installing the player. The trouble started right after that ad popping up.
CONCLUSION
So, Adobe has sold out. Not only is Flash responsible for most viruses transmitted, now just to get the player Adobe itself is shoving an obnoxious ad in our faces which installs a trojan. A Malwarebytes scan before the Adobe-shoved ad came up clear. Another scan after the Adobe-shoved ad detected a trojan and attempted to remove it, but it just comes back every time you restart the machine, and copies your business machine's hard drive out to the network.
So, Adobe, who has obtained copies of my business's intellectual property (I'm a software developer) and financial records, as well as sensitive data such as accounts and passwords?
CONSEQUENCES
Incidentally, this came at the moment when I was transitioning from developing native applications for desktop and mobile platforms. It was my intention to transition to using Adobe Flex for most work in the next few years at least. I had the Flash Builder on two of my systems, and was starting to work with it.
But this incident, combined with numerous past incidents that have made me absolutely hate both Flash and Adobe, was the final straw. I have deleted all Adobe products from all of my systems, and will not be using Adobe Flash or Flex or any other Adobe products for development or anything else. Now I understand why Steve Jobs also dumped Adobe -- it's nothing but a viral company! Adobe itself is like a virus.
Thanks for wasting a day on a holiday weekend trying to restore my system just so I can resolve a minor customer issue. Thanks, gals. Hope you enjoy the millions you get from that advertisement, but in my case it caused me to return to native development for all platforms instead of using Flash, Air, Flex, or any of the other viral stuff you use to invade 99% of all systems on the planet and then shove ads and more spyware on us.
I've also uninstalled Photoshop. (The uninstallation took 45 minutes.) I can just use GIMP, it's good enough now. Adobe = BANNED, because all that Adobe stands for anymore is VIRAL.
Thanks again
