I’m not sure how to describe it but here goes. An icon suddenly appears and disappears in my taskbar. I’m not familiar with the icon and I’m not able to see it clearly because it just stays there for a split-second. I’m not able to make out the pattern when it will appear.
I scanned my computer using ESET and Malwarebytes and nothing shows up. I’m bothered that it might be a keylogger.
Where on the taskbar? Is it showing up like a program or is it over by the clock?
If it’s over by the clock, is it actually disappearing or just hiding? Trying clicking the little arrow that displays all the icons and see if it reveals itself.
Also, if it shows up with any regularity, try to be ready with with your finger on the Print Screen button and get a screen shot.
It’s almost certainly either some sort of notification, or else an automatic update or something similar that was installed by the manufacturer of your computer. I have an HP computer, and every so often I’ll see an HP icon pop up very briefly in the taskbar, and then disappear. The CPU goes active at the same time, so it’s obviously an update process or something like that.
Looks like a picture associated with some type of scanner or camera software. It may be a driver some drivers or legitimate software cause nuisances like that. If you don’t want it popping up you have to stop it from starting or uninstall it by the uninstall feature in windows or task manager.
Could be a wireless printer or camera that’s intermittently connecting? If you don’t have such a beast, it might even be a neighbor or something if you’re somehow inadvertently connecting to their network, or they yours.
