First of all, thanks to BleepingComputer for having this forum and resources available. Part of my job is removing viruses from infected computers, and I refer to bleepingomputer.com frequently. Internet Security 2010 is a nasty virus, and there's a bunch of similar ones out there. Personal Security is one that comes to mind, but there are many others. They all basically want your credit card, but giving it to them does NOT remove the infection. I can't tell you how many people I talk to daily who admit to having paid these companies, and I wonder how many others are too ashamed to admit it.
I'm glad Malwarebytes removed Internet Security 2010 for you. MWB is a fine but limited program. It may remove the symptoms of the virus for a few days, but a significant percentage of the calls I receive are from people who ran a full scan just a few days earlier, only to have the virus return.
The ten-second solution? Dump XP and get Windows 7, and do not
run it from an administrative account. That's not a guarantee you'll stay virus-free by any means, but it will reduce the likelihood of your machine becoming infected. Additional measures that should help: Don't install any toolbars (BHOs) on your browser. Don't install any free screensavers or games. Stay away from free music downloading programs. Keep your antivirus program up-to-date and update and run Malwarebytes about once a week. If you have Windows Defender, update and run that regularly as well.
