Lately, every time I boot up or restart my computer, a message box appears on the screen titled "Steam"; the message is, "Verifying installation ..."; the box also contains a progress bar and a "Cancel" button. The supposed "verification" takes approximately 3 to 4 minutes to complete.
Is this actually from Steam or is it a scam of some sort?
If it is authentic, what happens if it finds something that does not verify? Will Steam still work properly if I click the "Cancel" button before this supposed verification completes?
Lastly, why doesn't Steam inform its users of a new procedure such as this?
I'm also wondering whether anyone else is seeing this Steam verification box.
