Email Attachments come in many forms including; documents, pictures, videos, etc. Most are harmless, but not all, and if you open one not, you should get your computer into the hands of the experts at 775PC to clean up your computer. One if the biggest problems is when someone has a virus on their computer and doesn't know it. The virus may invade their contacts and email each person with a replicated virus included as an attachment, thereby perpuating the virus. So the rule is, if your not expecting the email, or not sure if you should open it, then don't. Simply delete it or contact the sender to check on it's legitimacy.
Email Attachments
From Wikipedia, the free encyclopedia
An e-mail attachment (or email attachment) is a computer file sent along with an e-mail message. One or more files can be attached to any email message, and be sent along with it to the recipient. This is typically used as a simple method to share documents and images.
Size limits
The e-mail standards such as MIME don't specify any file size limits, but in practice e-mail users will find that they can't send very large files. Over the internet a message will often pass through several mail transfer agents to reach the recipient. Each of these has to store the message before forwarding it on, and may therefore need to impose size limits. The result is that while large attachments may succeed internally within a company or organization, they are unreliable when sending across the Internet and for that reason sending systems often arbitrarily limit the size their users are allowed to submit. As an example, when Google's Gmail service increased its arbitrary limit to 20MB it warned that: "...you may not be able to send larger attachments to contacts who use other email services with smaller attachment limits....". Email users can be puzzled by these limits because the MIME encoding adds up to 30% overhead[4] so that a 20MB document on disk exceeds a 25MB file attachment limit.  

Dangerous file types

E-mail users are typically warned that unexpected e-mail with attachments should always be considered suspicious and dangerous, particularly if not known to be sent by a trusted source. However, in practice this advice is not enough "known trusted sources" were the senders of executable programs creating mischief and mayhem as early as 1987 (with the mainframe-based Christmas Tree EXEC), so since the ILOVEYOU and Anna Kournikova worms of 2000 and 2001 email systems have increasingly added layers of protection to prevent potential malware and now many block certain types of attachments.
