are you sure about the spelling of that suffix.
You say xlxs, is that a typo? It is supposed to be xlsX.  If you didn't fumble finger your question, try correcting the spelling on the file name.

Actually, just for the "hallibut", try renaming it to XLS and see if it will open ...

If the file extension is correct on the file, it could be that the file was corrupted during emailing.
Ask them to send you another copy of it.
Actually, ask for 2, make the second one a XLS (if you are not depending on any 2007 specific features).

How to Avoid Downloading Malware

Where are you getting the download?

There are malicious people who download valid copies of a popular download, modify the file with malicious software, and then upload the file with the same name. Make sure you are downloading from the developer's web page or a reputable company.

Don't install download manager

Many sites suggest or require you to install an installer or a download manager before allowing you to download a program you may be interested in downloading. These tools almost always cause your computer more problems and may even have malware or other spyware. Avoid any site claiming anything must be installed first before you can continue with your download.

Avoid advertisements on download pages

To help make money and pay for the bandwidth costs of supplying free the software, the final download page may have ads. Watch out for anything that looks like advertisements on the download page. Many advertisers try to trick viewers into clicking an ad with phrases like "Download Now", "Start Download", or "Continue" and that ad may open a separate download.

Cancel or deny any automatic download

Some sites may automatically try start a download or give the appearance that something needs to be installed or updated before the site or video can be seen. Never accept or install anything from any site unless you know what is downloading.
