Help, I've got computer problems. My son downloaded photos from his I phone to a folder on my computer. At this time, something created shortcut icons on the pc. The entire screen is covered. They are IMG- followed by 4 numbers. There has also been some type of E-mail application called "drop box" that wants me to sign into each time the computer is turned on.
If you left click on one of them, the message appears "the system cannot find the specified file"
If you right click on one and try to open it, the same message appears. I can delete it, but it appears that a new one replaces the deleted one.
Avast says no virus, spy bot says no spyware. Any suggestions.
