What sign? Are you logging into your Exede account or running some software that checks your usage? Please describe what you mean or the sequence you go through after booting your computer until the "Sign" pops up.
Hi Larry, Please explain what error message you are getting and from what web address. If you have data, you should not be getting any messages regarding data used us. That may be mal mare. Please send your account and contact information to email@example.com.
That sounds like a spammer has attacked your computer, or as Diana stated, you may have malware. This is not something that is sent by Exede. If you would post a screenshot of this "sign" on the forum, it would help others understand what you are talking about.
