strange pop up, out of nowhere, can't stop it
This morning, a pop up appeared in the exact cente of my monitor. it is a blue square, titled Contrast/Brightness, shows what looks to be adjustment bars that blink back and forth. I tried restarting, starting up from a different start up disk, tried starting from CD, and it always is the first thing to appear on the screen. I dont click on unknown email atachments, or download **** etc, so I am surprised to see this. I do however hook up my Android phone to my mac as well as a non-ipod mp3 player.
I am currently running sophos to find malware. Avast found nothing. It may be messing with my intenet connection too, as i am getting err connection errors,but i won' be sure until sophos finishes scanning and i can reset the modem.
in the meantime, the stupid blue window is there blinking, and just about is causing me to have a seizure.... I googled this issue, found absolutely nothing about it. I hope someone heer can help me!
