Google Chrome : High speed with big trick!

Everyone now must have heard about the powers of the new Google's browser "Chrome" and its high speed in browsing the web specially the feature of multitabbing. All that are really very good and indeed it is better than Microsoft internet explorer and also faster than Firefox ,but it has a big problem. This problem isn't inside the program itself ,but it is in what google do with its browser.The Federal Office for Information Security in Germany has warned  German people from using Google Chrome as it allows Google to reach to the personal informatoin of its users and that is what Google said in the item No.1 of Google Chrome privacy policy which give Google all rights to get to your content and publishing it. So, I advise you not to use this browser and Firefox will give you what you want: the speed and the security.

Toshiba laptops are with Norton now

Toshiba has signed a contract with Symantec to provide Toshiba laptops with Norton 360 and Norton Internet Security 2009. The users can use these programs for 60 days for free and after this period, they should pay for them. Symantec will provide its antivirus program with three languages (English,French and Spanish). This contract is only an advertisement for Symantec products and I think they chose Toshiba for this deal as its laptops are expensive and its customers can easily pay for the Symantec antivirus programs. But in my opinion it's a bad thing from Toshiba to agree to this deal because it may cause problems for customers who don't want to use Norton as their internet security suite as it slows their computers and uninstalling it is very difficult.

Don't play with Firefox 3 !

The latest Firefox 3 isn't compatible with many adds-on that work with the

older versions of Firefox.So, many websites give a way to change the 

browser settings to make the old adds-on work in Firefox 3.This is a 

dangerous process that makes the browser unsafe and opens security ports.

Also, after changing some settings and install the old adds-on, Firefox 3 may

not work and not be able to connect to the internet ,so please wait until the complete version of Firefox 3 is available in the end of this year

and don't play with Firefox 3!

How to prevent losing your data and information caused by your computer!

Not only viruses and spyware can cause data losing
,but also your window does that.
To make the applications work faster, windows uses
a new technology called "Write behind caching" and that means
if a program wants to write data no the hard disk
,windows tells the application that the data have already been written on the disk
,but actually they haven't.
Windows waits a suitable time to write data on the HD.
What will happen if any problem occurs
within this time like a technical problem or the power is cut off?
Easily all unsaved data will be lost.

For more security ,you can disable this function :
1. From start menu open "Run".
2. Type "Regedit" then press open.
3. When the "Registry editor"window opens ,click on "HKEY_LOCAL_MACHINE",
then open system > CurrentControlSet > control >File System.
4. If this feature is being used on your computer,you will find "Write behind caching"
on the right "Write behind caching".make the mouse pointer on it
then press the right button.
5. Click "Modify" then make all numbers in it equal "0"zero ,all that to disable this
feature then press"OK".
