I don't know of any other software that can do this so I usually use Microsoft Paint to do this. Sometimes I want to edit out some information that are in the screenshots that I take. I don't know of any software that can securely blur out the information. I'm always afraid that someone can take the blurred images and then use some powerful software to unblur it. If I use Microsoft Paint's eraser feature, "erase" those information from the screenshot, and then save it as a new JPEG, will someone be able to recover the information that's been "erased" with Paint's eraser feature?

No. Once you save a JPG where parts of it have been "erased" or even blacked out, it cannot be recovered without access to the original, unaltered screenshot.
