Already two years since Intel introduced the great Core 2 Duo processor. Today, Intel officially introduced the new generation desktop microprocessor, Core i7 (previously known by code name of the Nehalem). This new CPU faster than the Core 2 Duo, even ordained as the fastest CPU available at this time.

Core i7 launched in three versions Quad-core target for the three segments of the different desktop PC market. The first is the basic model 920 (2.66 GHz) with the official price of U.S. $ 286. The second model is 940 2.93 GHz with a price of U.S. $ 562, while the third model is the 965 Extreme Edition 3.2 GHz with a price of U.S. $ 999.

Seen from the price, Core i7 is not cheap. However, if you want to create a PC with a Core system i7, you have to pay expensive. For the system, your options are currently limited to the motherboard with Intel’s X58 chipset (with ICH10 Southbridge) and DDR3 memory. Prices are not cheap both.

However, this new processor offers several new features, among other controls memory and integrated of the new Turbo. Hyper threading also appear again, adding to the four cores virtual four-core physical CPUs in the Core i7.

Mode Turbo, which is called Dynamic Speed Technology, allows the CPU to turn the core and increase the clock speed, which can be useful in applications that require long more megahertz, not the core of many more. In the multiple-Threaded applications, the CPU will balance the load on the entire core.

This new CPU has 731 million transistors die in one square millimetres-sized 263. All i7 Core processor is designed thermal design power at 130 watts. Quick Path Interconnect interface provides the bandwidth of 19.2 seconds in the pre giga transfer models 920 and 940, and 25.6 giga transfer the Extreme Edition model.

World of information technology need to be vigilant. Rootkits technology , which have the same ability with the operating system, has been used to bring the virus into the computer.

Rootkits is a software which designed specifically to manipulate the operating system directly to the hardware.

According to antivirus specialist Anvie Anzav, Rootkits, which have access to the higher than administrators, the same as the operating system. “Initially Rootkits created to help restore the administrator password is lost but had misused for the damage, create viruses, and even make a bomb,” said Anvie in Indonesia Hacking and Security Conference at Jakarta Convention Center (JCC), Saturday (15/11).

Anvie says Rootkits can create an object is not visible (stealth). This function creator of the virus used to disappear so it self is not detected by antivirus software. Rootkits can also use the access rights from the admin higher than that with the operating system so that it can do all the things that made the operating system.

Impact is the most Rootkits can explode if a computer virus technology with Rootkits can govern the hardware to do what, for example, the processor. “The rule (the processor)’s operating system that provides access to standard processors that can not exceed the limit of about lap or was working on. So Rootkits can use the processor without the permission of the operating system. It can tell the processor continuously rotating at high speed, and how lap never finished, finally sound of gunshot, and explode! ” Anvie said.

Difficult to detect

The existence of the virus fully difficult Rootkits detected by antivirus software, in some cases even computer viruses that have infected fully Rootkits will reject if users want to install antivirus software.

This is influenced by how Rootkits work, for example, Direct Kernel Object manipulation (DKOM) where the object in memory manipulated. “When the process is running Rootkits removed the object, so the operation did not know there are processes that are running. Or when deleted, rootkits slew command,” said Anvie.

So how to overcome them? Anvie says Rootkits can be detected with a simple comparison to make between the object and RAW snows and access to the dump (data) in the physical memory directly.

Devices that can help, among others, Ice Sword or Rootkits Revealers. However, according to Anvie, Ice Sword is supporting applications that can only remove Rootkits normal. If the head of Rootkits and rough entrance, all of the operating system can be so open-block computer can not be done. So, what should I have to prepare? “You prepare with black magic,” said the Anvie with a laugh.

Sometimes, when we are doing defrag our hard disk, a message appears

“Error Defragmenting Drive C, Windows can not finish defragmentting this drive because it has encountered a problem. Click Help and carry out the instructions for running Scan Disk, and then try defragmenting again..“

After that, the defrag process stops.

Do not immediately panic! I follow the advice given on the Windows error message was, namely, run Scan Disk to check the condition of the hard drive. Once the disk scan is complete, try to defrag again.

Now, if the suggestions have been run Windows, but the hard drive is still unwilling in-defrag, follow these tricks.

1. Click [Start] [Settings]> [Folder Options ...].
2. Select the tab [View], and then click the option [Show all files].
3. Press the [OK] to exit from the windows “Folder Options”.
4. Click [Start] [Find] [Files or Folders].
5. Type “applog” in the column “Name”, and in the combo box “Look in:” select the drive [C].
6. Check the box [Include subfolders].
7. Do a search by clicking on the [Find now].
8. After the search ends, delete all the files found (except the folder C:-Windows-applog) and then double click the folder and delete the applog entire contents of the folder in it.
9. Close the search window and run the Disk Defragmenter again.
