Hello Again,
This Week we will cover cleaning out laptops and desktops physically to eliminate dust.
One of the most common problems for computers today is heat. Heat is created by components of a computers as access consumption. This will be true till we have 100% power efficient electronics, until then we will have to do a bit of house keeping.
All we need is a can of compressed air.
Desktops
Now to clean out a desktop you can either spray from outside the panel or inside. Meaning that you can take the side panel out and spray or just spray through the ventilation holes. Obviously the best approach is to take the side panel off. Now for some people that might be the best option either because your desktop could be extremely complicated to open (Yes I can have a trouble sometimes to, These designers can be satanists sometimes). Normally you would just unscrew 2 screws holding the side door in place then slide it to the back and it is off. If that is how you do it great if not it will still help to move some air in there by spraying through the vents.
If you remove the cover the area you want to spend the most time on is the heatsink which is piece of metal sitting on the motherboard. Give this the most attention since this is where your CPU is. Make sure to remove all dust bunnies and remove any dirt from the fans so that they can run smoother and probably quieter as well. Never use any liquid inside the case!!!
Laptops
Now for laptops if you don't want to take it a part(which can be difficult) the best solution is to power it down. Then to spray air into the vent slot. There should be two of them usually one on the bottom and one on the side. Try going back and forth and blowing air in both of them and see which one brings out more dirt. Any air you blow through one should be felt through the other vent. One is to suck air in the other is to let it escape.
I hope this helps
This is something that should be done every 6 months at least and for smokers it should be every 3.
Thanks for reading
feel free to ask any questions
Compressed air is sold at any walmart-k-mart or computer store as well as

New iPhone Speculation
The majority of my posts are and will be actually truth and known facts. My goal is to help educate people about computers and internet security. As well as helping to spread awareness about the internet because one it is fragile(which I will talk about in future posts.) but secondly it can also be dangerous.
My goal with this blog is to help give facts to the users however this post will not be following those guidelines. This post is all about iPhone speculation!
I myself have an iPhone 3gs..... Sadly my contract is up in a month and I still don't feel the need to upgrade. I know I know the iPhone 4 is awesome I fix them I have taken them apart I know... Trust me they are cool.. But they are not capable of doing the one thing they are almost advertised to do is run on a 4g network (that includes the Verizon version)
Ok above are facts below is speculation......
I believe that their will not be a new iPhone version this year for either AT&T or Verizon. I do believe that they will be releasing a white version of the iPhone 4. Below is my evidence.
1. They have not released any new iPhone OS to any developers. This is done in order for app developers to have plenty of time to flood the market new/updated apps to take advantages of any new feature/hardware updates. This is usually done 4-8 months before a new release is scheduled.
2. The number one supplier of iPhones is AT&T and they currently do not have a 4G network in place. As well as Verizon's 4G network does not really meet the (quasi technical non standard definition of 4G{There is no government standard guidelines for 4G network, anyone can say they are 4G in reality}). So why would Apple screw up a good thing. They know this phone will keep selling. And that when they release a new phone they will still sell just as well. So why rush until the network is actually in place giving them time to perfect the phone's antenna problems.
2.1 An AT&T and upgraded Verizon Network could finanly get to 4G speeds most likely sometime in the fall from what I have read. So that would put a good guess at a new iPhone probably around January 2012 a new iPhone 4GS .
3. An argument for a white iPhone, is because the manufacturer I deal with for parts has been selling iPhone 4 white conversion kits since January. These are the real deal. I have them as well as green,pink and red conversion kits. They look sharp.
That's my argument feel free to add any ideas.

Bluetooth & Your Security
One new way open to Hackers is Bluetooth.
For those that don't know Bluetooth is a wireless connection similar to Wi-Fi.
However it can make your computer extremely vulnerable to a person with the right knowledge.
This goes for GPS,Cell Phones and any other gadgets with Bluetooth.
Someone can take control of the device or even still information off of it.
In fact I believe this is most likely how a hacker published Paris Hilton's phone list on her phone.
So turn it off if your not using it that is the safest way to go.
If you can set a password do it and make it a tough one add numbers or a capital letters mixed with lower case.
But in some cases you can not add a password.
But a password still does not guarantee safety.
Having it turned off is the only way to keep the bluetooth portal shut to would-be hackers.

1 in 290 emails are malware
About 1 in 290 e-mails in February were malicious, making the month one of the most prolific periods for the threats, according to Symantec’s February 2011 MessageLabs Intelligence Report.
So think twice before you open an e-mail from someone you don't know.
If you still want to check it out, clear out your spam folder, then mark it as spam. Then find in the spam folder (only one if you cleared it before hand) and then open it.
In the majority of e-mail servers, usually disable html/java script in e-
mails. Which would disable any launch programs from an e-mail. However if you click anything in that e-mail it could take you to a website which you will NOT be protected.
Happy Browsing...

How to Prevent a Hard Drive Crash
Something that we have been seeing a lot more lately is Hard drive crashes. This has always been a pretty common problem. But I feel in the last couple of months it has ramped up. I remember during Windows 98 era most common users were aware of features like disk defragement and Disk Check. Now I feel it is almost a lost art with Windows computers users. Both Disk Check and Disk Defragment run through Windows and can help prevent failures.
Disk Defragment Works by checking hard disk for bad clusters or sectors on the physical hard disk. Bad sectors occur when data is written to the disk over time and the data is spanned out over larger sections of the hard drive decreasing speed and life expectancy.
The average lifespan of a hard drive is 3years...
Always Back up your data Data recovery for a failed hard drive can cost over 1000$

Understanding Malware, Spyware & Viruses
Spyware & Viruses are programs that are designed to disrupt a computer system. Both have similar goals but for different reasons. Both are considered Malware because they are malicious in nature. Both can be specifically targeted or just picked up at random.
Spyware is more associated with scams and ID theft. The goal of spyware is to scam you to trick you to pay for software that has been installed on your computer with out your knowledge. This is done by usually tricking you to click on a link or pop up that states you have an infection and it must be cleaned. Once you click on the malicious pop up, you unknowingly give the program permission to install malicious software on your machine. Spyware can block out internet access and render your machine useless if it becomes heavily infected.
Viruses on the other hand in the past have been more malicious in nature. If you remember during the late 90's and early 2000's the CIH virus which ran wild for almost 2 years. Also if you can remember the rumors of computers melting or blowing up because of a virus. This is largely untrue for the average computer user. Mostly virus these days are trojans that try to recover stored passwords for e-mail and bank accounts. However just recently a computer virus was placed in a computer running a Nuclear reactor in Iran and caused wide spread damage by running the machine at an extreme rate while showing old video tape surveillance of the reactor running normally. http://www.bbc.co.uk/news/technology-11388018
