I heard on the news that there is a virus going around that makes it look like there is a tracking number from either Fed Ex or UPS and if you open it you will get the virus
They said do not open them or the virus will mess up you files and they want a bribe to make the files right again, but they take the money and leave not fixing you puter
When they said the last part I was wondering if there actually are people who are dumb enough to send them money to fix something they messed up
If you are expecting packages go to the shippers web site and track it there
