Spam Viruses

Spam spam spam...wonderful spam. Everybody loves getting tons of random emails about random things we never even wanted to know existed. It's even better when we receive it from someone we know and trust. Without thinking much of it we click on the link that says something like "I saw your picture on this website!" and now suddenly, our computers are host to some very unsavory guests.

Where do these come from, and what do they do?

The main purpose behind these spam viruses can be any number of things. Sometimes it's to gather important information off of your computer, damage system files to cause problems, and many times it's just to annoy the heck out of people.

These viruses can come from plenty of places. One of their main methods for spreading is by email, using your address book. They will use two email addresses at a time, one for the sender, and one for the recipient. That way whenever someone receives this spam message, it shows up as coming from someone else entirely, and it's very difficult to trace back to the infected computer.

If you are very fortunate the virus might not be placing a random address in the sender spot, meaning the virus is on your computer and you can do something about it.

What can you do about one that isn't on your computer? Regrettably not a whole lot. One option would be to email everyone on your address book and suggest they check their computers for viruses. Definitely not an appealing way to spend the day for those with a large address book. You can also try contacting your email provider and asking them about spam filtering. Beyond that you just have to hope that whoever has the virus gets some de-worming medicine for their computer.

So as always, be careful of any emails you receive that look suspicious. If you're unsure if they are safe try contacting the person that sent it to you to ask, or do a Google search on the subject line of the email to see if it is a known spam message.

Email is Email...What's this POP3 and IMAP business!?

Who doesn't have an email address these days? If you don't...then you are probably on the wrong website...or you need to contact me so we can set you up with an email address right now. Anyway, now and again you will see email referred to using POP3 and IMAP. What the heck are they and how do they affect you?

A POP3 email account means that the emails are stored on the service provider's computers (providers like Telus, Shaw, Platinum, etc). An email client on your computer (programs like Microsoft Outlook, Outlook Express, Thunderbird, and Windows Mail) then downloads the emails and removes them from the service provider's computers (unless the settings to leave a copy are turned on). That means that no other computer is able to receive the email after the first time.

An IMAP server is similar to POP3, except that your computer does not download the email, it all stays on the server and your computer only downloads the information for you to view. So when you send, receive, or delete any messages all the changes are done on the IMAP server. That way you can access the same email from any other computer that is set up to connect and it will be exactly the same. This is really useful when you want to check your email from multiple devices, like a laptop, desktop, or even from a public computer online (using webmail).

Where do you get an IMAP account? One option, Gmail, is a very easy, free, and user friendly email service that supports both POP3 and IMAP. There are also plenty of guides and instructions right on the Gmail website to show you how to set it up to connect to an email client on your computer. As an example, I use Gmail for my business email and have it synchronized between my laptop, desktop, and Google Android cellphone. Not only does Gmail handle my email, but it also stores my contacts and calendar information and keeps all my devices up to date.

So if you only have one computer, and never need to check your email away from home, then a POP3 would work just fine for you. If you want a little more mobility and freedom when it comes to reading your email then POP3 is capable, but IMAP is probably a better option.

EDIT: I recently discovered another difference between the two types of server. A POP server is not well suited to having multiple devices access it within a short period of time. When an email client accesses the account it is locked from other clients for a time. It is finally released after about a minute. This isn't usually a problem unless you a setup similar to having an email client on your computer and phone both checking your email frequently. One client can block the other and you will end up with errors. IMAP server do not have this restriction.

Laptop, Notebook, or Netbook?

What is the difference between these three types of portable computers?

Many people believe that a laptop and a notebook are exactly the same. The names are often used interchangeably and are thought to mean the same thing. But as explained here, there are differences between a laptop and notebook.

A notebook is similar to a laptop, but it is smaller (12" to 14" screens), does not have a CD/DVD drive, has a slower processor, and has a low end graphics card. As a result, the battery life is usually much better than a laptop.

So when shopping for a laptop/notebook don't worry so much about what the name says. Pay more attention to what hardware the system has.

A netbook is similar to the notebook with the exception of a smaller screen (usually 8" to 12") and an even slower processor. But, like the notebook, netbook's have a low end graphic card and a long lasting battery.

So make sure you know what requirements you have (portablility, battery life, screen size, etc.) and shop around for the best option. There are plenty out there.

In The Beginning

Hey!

For years I have told myself "I will NEVER have a blog, I don't have anything interesting to say"...well now I have a blog and I still don't have anything interesting to say, but we're taking baby steps.

The point of me having a blog? Good question...when I figure it out I will let you know! No, no, I'm kidding...The point of this blog is to give me a place to post the tips and tricks I have discovered over my years of working with computers. And hopefully, if you read my posts, you will learn something new.

I have been repairing computers for almost 7 years now, and for years before that I would tinker away in the basement. I enjoy working with them, and helping people understand a little more about them. For the past 2 years I have wanted to get training courses started, and while that is a goal for the future, my hope is that this blog will be a step in the right direction.

So look forward to posts from me and people that work with me, about anything to do with computers and various other electronics. Have a question you want answered? Please send it to me, I would love to hear from you, answer your questions, or even let you name your first born after me ;-) but I won't hold my breath on that last part.

Until next time,
