Last night, while on Firefox my screen's brightness randomly increased to maximum. I would have assumed that I'd hit some weird shortcut by accident, except that all my windows, as well as the taskbar, had reverted to some default Windows theme at the same time. I had never seen such a theme before, but it was undoubtedly a version of the old Windows default.
Only my wallpaper remained unchanged. I then went to the Control Panel to try and fix everything, but the settings said that there had been no change. I then rebooted, and everything looked normal again.
I am running Windows 7 (64-bit) on my HP Pavilion laptop, which is less than a year old. I am concerned because I've already got a little trouble with the fan, and bad luck with a past computer has made me paranoid. Has anyone else seen or heard of this? Is this a bug? A symptom of malware? Or something I did?
The brightness maxing out randomly hasn't happened to me before, but one time ZoneAlarm did open in a window similar to that default theme- everything else at that time was normal, however.
Now, I'm pretty sure that I hadn't hit any weird hotkey to increase brightness. I wasn't downloading anything at the time, or visiting any suspicious websites. I keep my machine pretty well protected with ZA, Avira, SpybotS&D, and SpywareBlaster, and update them and Windows Update regularly. That said, other than this, my laptop seems to be running fine...so far. Any ideas?
Thanks in advance.
