A spam bot is one of the latest ways spammers get their emails delivered. When you get a spam bot virus your PC turns into a “zombie” PC wherein it will begin sending large quantities of spam email through your PC and internet connection, causing your PC to slow considerably. Even more dangerous are viruses that monitor your keystrokes for any passwords and financial information such as credit cards or bank account numbers. I have known people whose chequing accounts were ‘compromised’ more than once (one person I know had $1000 taken from their account) and this may have been due to them doing online banking and hackers picking up on their financial information through viruses on their computer.
To counter email viruses, make sure you buy a good anti-virus program such as Norton Anti-Virus. Just as important is keeping your anti-virus license current as this type of software is only as good as the updates it gets. Hackers are always one step ahead of the companies they’re posing as. When a virus gets widely propagated companies like Norton will act quickly to create not only a cure for PCs infected with the virus but the ability for your PC to scan attachments for this virus and get notified immediately if the attachment has a known virus.
Emoticons - many of you will recognize what these are but don’t know what they’re called. These are for expressing emotion in emails with little sideways faces where the emotion might otherwise not get picked up on. For instance, 
is a happy face, :> is a really happy face, 
is sticking your tongue out, 
is a blinking happy face, and so on.
Follow-Up – when using Microsoft Outlook this works in conjunction with flagging. When you flag an email, you’re marking it to remind you to take specific action on the email’s content by a certain date and time. Once you’ve completed the related tasks you can un-flag the email.
Header – the email header is all the information about an email that’s stored within each email as it’s sent including the technical stuff. The header helps the email get delivered and structured properly for the recipient. The only time you usually ever have to include the header information in your emails is if you’re asked to prove something.
