(AP) — Nebraska’s attorney general is warning residents about phone scams related to computer technical support.

Attorney General Jon Bruning says in a release Friday that his office has recently received multiple reports about individuals calling residents and falsely claiming to represent Microsoft Corp.

The individuals claim to be technical support professionals, and add that there’s an imminent security threat to a personal or business computer. The caller then tries to get sensitive information stored on the computer.

Bruning says residents should never provide access to a personal or business computer to people they don’t know.
