Most commonly used Security Techniques against viruses

Virus detection and its removal are mode through an antivirus or with some other security program. Different antivirus programs are available in the market and over Internet. The most common and famous security technique against viruses is as under:

Virus Signature/ Virus Definition
Virus signature is a known pattern of code of a code of a virus program; this pattern is used by antivirus program to detect viruses and then to remove these viruses. You should update virus definition continuously by downloading updates from Internet. This ensures that your antivirus is always able to detect changing viruses.

Inoculation
Inoculation file is separate file created and maintained by antivirus program to record information like file size and file creation date. This information later on is used for virus detection and removal.

Quarantine
Quarantine is a separate area on a hard disk. It contains the infected files and folders that cannot be cleared or deleted by antivirus due to some reason, for example sharing violation or unknown virus for that antivirus.

Recovery Disk
Recovery disk is a removable disk that holds un-infected system commands and startup information. In case the boot record of actual hard disk fails, this recovery disk can be used to start the computer. Afterwards an antivirus program can be used to remove the virus.

Un-authorized access
Accessing a computer system without the knowledge or permission of its user is called unauthorized access. It is always recommended to restrict computer resources with the help of usernames and passwords. These are unique combination of characters to identify users and their secret codes respectively.

Firewall
Firewall is a security system consisting of hardware and software to prevent unauthorized access of a network or computer. Big companies use a separate computer firewall software or hardware to protect their date from unauthorized access. Firewall check outgoing and incoming traffic and manage data access to the authorized users only.

Biometric Devices
A biometric device reads personal characteristics like fingerprints hand structure, facial features, and voice recognition to authenticate a user for any further access to a computer system or other peripheral devices. A biometric device translates the personal characteristics into digital code that is matched to already store user data in that system. If the digital data matches with any of the stored data, it gives access to the person. In case of no match, the access is denied.


Leona Lewis - Bleeding Love

Closed off from love
I didn't need the pain
Once or twice was enough
And it was all in vain
Time starts to pass
Before you know it you're frozen

But something happened
For the very first time with you
My heart melts into the ground
Found something true
And everyone's looking round
Thinking I'm going crazy

But I don't care what they say
I'm in love with you
They try to pull me away
But they don't know the truth
My heart's crippled by the vein
That I keep on closing
You cut me open and I

Keep bleeding
Keep, keep bleeding love
I keep bleeding
I keep, keep bleeding love
Keep bleeding
Keep, keep bleeding love
You cut me open

Trying hard not to hear
But they talk so loud
Their piercing sounds fill my ears
Try to fill me with doubt
Yet I know that the goal
Is to keep me from falling

But nothing's greater
Than the rush that comes with your embrace
And in this world of loneliness
I see your face
Yet everyone around me
Thinks that I'm going crazy, maybe, maybe

But I don't care what they say
I'm in love with you
They try to pull me away
But they don't know the truth
My heart's crippled by the vein
That I keep on closing
You cut me open and I

Keep bleeding
Keep, keep bleeding love
I keep bleeding
I keep, keep bleeding love
Keep bleeding
Keep, keep bleeding love
You cut me open

And it's draining all of me
Oh they find it hard to believe
I'll be wearing these scars
For everyone to see

I don't care what they say
I'm in love with you
They try to pull me away
But they don't know the truth
My heart's crippled by the vein
That I keep on closing
You cut me open and I

Keep bleeding
Keep, keep bleeding love
I keep bleeding
I keep, keep bleeding love
Keep bleeding
Keep, keep bleeding love
You cut me open and I

Keep bleeding
Keep, keep bleeding love
I keep bleeding
I keep, keep bleeding love
Keep bleeding
Keep, keep bleeding love
You cut me open and I
Keep bleeding
Keep, keep bleeding love

Gunung Ledang


The legendary beauty of Mount Ophir (Gunung Ledang) has made it one of Johor's most popular attractions for hikers and birdwatchers. There two known ways of reaching the summit. One is from Sagil, a town in Johor, the other is through Asahan, Melaka. The shorter route is from Asahan. Gunung Ledang ( or Mount Ophir as it is otherwise better known ) is the most visited mountain in Malaysia. It is not peculiar to find people who has climb the mountain more than 10 times. The reason being, the place is easily accessible and suitable for beginners who wants to feel what mountains in Malaysia are really like. Some groups are using this mountain as a training ground for other challenging venues.


The Ledang trail starts from Gunung Ledang resort, near Sagil village is close to the Malacca and Johor border. The other way of reaching the summit is through Asahan trail in Melaka, an easier route. The paved road starts besides the river leading and leads towards a few staircases till an open gate, where the real climbing begins.


Gunung Ledang is believed to have the richest flora species in the world. It has a 50 metres high waterfall with a wide drop of 50 metres. It has icy cool waters charge down upon large boulders, then break into rushing rapids before plugging into the large sandy pool below. This waterfall, discovered some 50 years ago, is name the "Puteri Waterfalls". Over the period it has witnessed thousands of tourists almost every week, picnicking, backpacking or just bathing in the refreshing water of the pool. You'll see giant butterflies, brightly coloured spiders amidst wild tropical flowers of bright yellow, crimson and orange.


Crickets and frogs singing song of the jungle, chirping sounds of birds become the music of this tropical wonderland. The summit was just beyond the boulders. There's a flat ground revealed at the summit of Gunung Ledang at 4187ft. Wide and flat, mystical and lovely. I can get a panoramic view of Segamat and Jementah town of Johor, and the historical Melaka.

Movie Review : Iron Man


Much of the allure of "Iron Man" comes from the fact that we are indeed talking about a man -- a real man who has lived a life and made mistakes and experienced regret -- not some scrawny, teenage boy who received his superhero powers through a bite from a radioactive spider. No offense to Spidey, the other Marvel Comics hero who's already provided billion-dollar summer blockbuster fodder. But there's just something more relatable about Tony Stark, even though he's a playboy industrialist of staggering wealth and arrogance. And in the hands of Robert Downey Jr., he's absolutely riveting. Downey may have seemed an unlikely casting choice at first, but it's difficult to imagine any other actor in the role; he's so quick-witted and he makes such inspired decisions with dialogue that, at times, might have seemed corny otherwise. Throughout his eclectic career -- from "Less Than Zero" and "Chaplin" to "Kiss Kiss, Bang Bang" and "Zodiac" -- he's always been capable of both great charisma and vulnerability, and both are beautifully on display in this, the biggest movie of his life. "Iron Man" is a blast, too -- the perfect start to the summer with its shiny mix of visual effects, elaborate set pieces and plenty of humor within its intelligent script.


This is also the biggest movie of director Jon Favreau's life following "Made," "Elf" and "Zathura," and he juggles all the complicated, expensive toys deftly. The visual effects come courtesy of the venerable Industrial Light & Magic, with Matthew Libatique ("Requiem for a Dream," "Inside Man") providing the crisp cinematography. The first moments of "Iron Man" give us a telling glimpse of Tony: a close-up of his hand, cradling a tumbler of Scotch on the rocks, as he rides in the back seat of a Humvee that's rumbling across the Afghanistan desert. He's the brilliant and talented head of Stark Industries, the leading supplier of weapons to the U.S. military, and he banters comfortably with the soldiers who have been assigned to protect him during a trip to demonstrate his latest missile. They, in turn, are in awe of his high-flying ways. But things go awry almost immediately. The Humvee is attacked by insurgents and Tony is abducted. While in captivity, with a battery attached to his heart to keep him alive, he's ordered to reconstruct the missile. Instead, with the help of the doctor who saved him (a graceful Shaun Toub), he's crafty enough to create a suit of armor and become a weapon himself to escape.


Tony returns home to his monstrosity of a mansion that's carved into the face of a Malibu cliff but looks more like an old set from "The Jetsons." He's a changed man, and the changes he has welcomed to his life and company also bring enemies. His top executive Obadiah Stane (Jeff Bridges, deliciously villainous with a shaved head and devilish goatee) is appalled at Tony's new purpose -- to no longer make weapons. But Stane insists, "What we do keeps the world from falling into chaos."


It's an anti-war argument in the multilayered script from the writing teams of Mark Fergus and Hawk Ostby, and Art Marcum and Matt Holloway, but the delivery is hardly heavy-handed. The original "Iron Man" comic book that inspired the film took place in the 1960s during the Vietnam War, and Tony Stark was relevant, functioning as an important, fervently anti-communist cog within the military-industrial complex. Moving the film's action to Afghanistan and the present day makes it just as relevant in its own way. In his tricked-out underground workshop, his own personal bat cave, Tony creates his Iron Man uber-suit, even though he's not quite sure what to do with it once he's finished: the right thing, perhaps, for the first time in his life?


His right-hand woman, Pepper Potts, stuck by him and kept his life organized when he was a shallow pig, but seems to like the more enlightened Tony better. (In another unexpected bit of casting, Gwyneth Paltrow brings understated smarts and class to the role.) Meanwhile, his best friend, Rhodey, an Air Force colonel played by an underused Terrence Howard, just seems confused by this person he no longer thinks he knows.


Tony undergoes plenty of trials and errors on the road to becoming Iron Man, which are both amusing and thrilling. But the moment he finally climbs inside that streamlined, rocket-propelled, red-and-gold suit -- with its perfectly intertwined pieces that lock together like the most comfy, high-tech pair of ski boots -- will surely cause the hearts of geeks and non-geeks alike to go pitter-patter.


But because the build up is so successfully engaging, the ending feels like a letdown. It's just plain silly watching versatile, Oscar-nominated actors behave like a couple of middle-aged Transformers. That's merely one bump in an otherwise satisfying ride, though. And there's plenty of opportunity for improvement: The last line clearly sets up a sequel. But you knew that was ironclad from the beginning.


"Iron Man," a Paramount Pictures release, is rated PG-13 for some intense sequences of sci-fi action and violence, and brief suggestive content. Running time: 126 minutes. Three and a half stars out of four.

Mitsubishi launches Evo X in Japan


Mitsubishi Motors Corporation has launched its Lancer Evolution X high-performance 4WD sedan in Japan. The vehicle is offered in its domestic market in GSR trim level, with a number of option packages that can be tacked on, these being a high performance package, an exterior styling package and leather combination interior. Also available, a Premium Package, which combines all the above packages and adds 18-inch BBS lightweight alloy wheels. The Evo X is also available as a RS competition base model, the latter coming with less comprehensive and simplified equipment specification to reduce weight to a minimum.


While the basic exterior shape is very much from the standard Lancer, the front end has been tweaked with larger air intake openings and new ducting to lend the vehicle a more aggressive look. New to the form, an engine hood air scoop and air outlet, as well as fender vents. At the rear, an oversized rear spoiler uses a twisted-section wing panel with different attack angles at its ends and in the centre portion to match the airflow over the body surface. A large undercover rectifies underbody airflow for better aerodynamics and also improves drivetrain cooling, and there's a lower rear bumper diffuser to help exhaust the underbody airflow more effectively.


The exterior styling package option uses a chrome finish for the front grille lattice and beltline molding, body colour-keyed fender vents and adds fog lamps to the equation. The new platform makes a significant increase in body stiffness, with gains being 40% better torsional and 60% better flexural stiffness over the Evo IX MR.


Power comes from a turbocharged 4B11-type 2.0l four-cylinder twin-cam pot, delivering 276bhp (206kW) and 422Nm of torque. The new engine, excluding auxiliary equipment, is 12kg lighter than the 4G63 thanks to the use of a die-cast aluminium cylinder block, head cover and chain case. The 4B11 is of course the same base engine as featured in the Lancer 2.0GT here and Galant Fortis in Japan, though revisions have of course been made for its use on the Evo X.
Using a titanium-aluminum alloy turbine wheel and aluminum alloy compressor wheel, the turbocharger features a shape-optimized compressor wheel that improves boost response and increases low-end and mid-range torque.


The adoption of a rearward facing exhaust manifold layout has, as well as improving exhaust efficiency, allowed the engine to be mounted lower, lowering the centre of gravity. Other innovations have reduced intake/exhaust system losses and valvetrain friction, contributing to improved engine performance.


The GSR is available with the new Twin Clutch SST six-speed automated manual transmission, which puts odd (1st, 3rd, 5th) and even (2nd, 4th and 6th) gears on separate input shafts each with its own clutch. The system allows the driver to choose between Autoshift fully automatic shifting and Manual Shift, where the driver can change gears as with a manual transmission. A toggle switch located at the base of the shift selector allows the driver to choose between Normal, Sport and Super Sport modes for the optimum shift scheduling. The GSR is also available with a new five-speed manual transmission (the RS version is only available with this manual gearbox). First to fourth gears use close ratios; 1st uses a lower ratio than previously for better standing acceleration, while 5th gear uses a higher ratio for more comfortable high-speed cruising. The new transmission uses multi-cone synchroniser rings on all gears for smoother shifting and a more positive shift feel as well as for improved durability.


The GSR trim level comes with the S-AWC (Super All Wheel Control) 4WD vehicle dynamics control system as standard, with three operating modes present — Tarmac for dry, paved surfaces; Gravel for wet or unmade surfaces, and Snow for snow covered surfaces. Active Stability Control (ASC) has been added to the ACD (Active Center Differential), AYC (Active Yaw Control) and Sport ABS component systems featured in previous Evo.


While continuing on the MacPherson strut front and multi-link rear suspension arrangement used on previous models in the series, the Evo X features a revamped suspension layout with wider tracks and 18-inch tires. The GSR comes standard with 245/40R18 tyres sitting on 18-inch Enkei 12-spoke high-rigidity cast alloy wheels. As a factory-fitted option, 18-inch BBS lightweight alloy wheels are also available. The factory-fitted high performance package is made up of Bilstein single tube shock absorbers and Eibach coil springs, as seen on the Evo IX MR. It also includes Brembo two-piece disc brakes, lighter by 1.3kg per piece over the standard Brembo discs, and high performance tires with stiffer walls and better grip.


Five body colours are offered in GSR trim, including a vividly sporty Red Metallic and a new classy and deep-hue Phantom Black Pearl, while the RS is offered in two body colours, including White Solid which is exclusive to this trim level.
