I am getting small windows popping up every once in a while on the bottom right corner of my desktop. Each time I get one of the windows they look exactly the same, but they tell me different programs need to be updated. Sometimes it's Adobe Reader, sometimes it's Google, sometimes it's other things.
I was suspcious because Adobe and Google are two different companies, so I didn't think the same program would be telling me about updates for both. Having a little computer knowledge, I ran Kaspersky and then Combofix and then Malwarebytes. All of the these found a few things and all of them removed what it found before I ran the next one.
A couple of days later I got a new (fake?) update message, this time indicating that my old Adobe AIR software should be updated to version 188.8.131.52.1430. I again ran Combofix, which again found and deleted some stuff. I also ran Malwarebytes, which did not find anything. I then ran Malwarebytes RootKit, which said something was blocking it from running (I think) and after it stopped the process that was running it, it ran and reported finding nothing.
I suspectthat I am infected. What should I do?
