I don't know what's happened, but the majority of my pictures on my computer have become unviewable and their file names are replaced with the same name but have a "._ in front of them. What happened? Is there any way to undo this?
Two things I would do. Right click the file and select Open With... and pick your image viewer. If that doesn't work try a different image viewer, irfanview is light and powerful.
Secondly, I would do a full scan with MBAM, in case it is malware behind this.

Files beginning with "._" are a convention of the OS X operating system. They're 'resource forks', little metadata files like Windows has .ini files, though "._" files are quite more abundant on OS X compared to .ini files on Windows.
Thed00d88, do you recall using the operating system recently?
You should be able to open "._" files in a text editor and see the string "Mac OS X" in plain text near the top.
