Just got my computer out of sleep. As is sometimes the case, the IE task bar icon on the bottom left was not highlighting when I put my cursor over it so I clicked the desktop as I usually do and the Password screen for signing in came up. I had to enter my password to get back to the desktop.
The only thing I changed about my computer recently was puttng a lot of my desktop icons into two folders. I restarted sometime after that because I found that malwarebytes was not making sound after scanning which was fixed by the restart.
I've noticed of late that when I restart the computer the taskbar icons on the bottom right seem to take awhile to appear which would be Avast!, VIA HD Audio Deck, Volume, and my internet access. I only have 6 programs that are set to launch at startup.
