MyBlogger@zidani: Mencegah Penyebaran Virus Melalui Perangkat USB

Mencegah Penyebaran Virus Melalui Perangkat USB

Cara penyebaran virus yang sekarang ini sedang booming adalah dengan memanfaatkan fitur Autorun yang ada pada sistem operasi Windows. Fitur ini sebenarnya sangat memudahkan kita yang ingin langsung membuka/memainkan file yang ada di media penyimpanan dengan segera. .

Tetapi para pembuat virus melihat fitur ini sebagai jalan tercepat untuk membantu penyebaran virus. Dengan menanamkan virus beserta file AUTORUN.inf yang sudah ditulis untuk menjalankan file virus di root directory flash disk, setiap kali pengguna menghubungkan flash disk ke komputer yang fitur Autorun-nya aktif, secara otomatis virus akan langsung dijalankan.

Untuk melakukan pencegahan virus menyebar dengan bantuan fitur Autorun kini Anda tidak perlu repot lagi, seperti melakukan langkah-langkah pengaturan yang panjang dan beresiko. Berkat aplikasi portable dari perusahaan keamanan PandaSecurity, Anda sudah bisa melakukan pengamanan terhadap tempat penyimpanan berkoneksi USB, seperti Flash Disk dalam beberapa kali klik saja.

Aplikasi gratis bernama Panda USB Vaccine ini (klik disini untuk download) memiliki dua cara untuk menangkal penyebaran virus melalui media penyimpanan:

1. Computer Vaccination - aplikasi ini akan menonaktifkan fitur AutoRun dari komputer bersistem operasi Windows secara menyeluruh, sehingga program/virus yang memanfaatkan file AUTORUN.inf dan berada di dalam USB/CD/DVD tidak akan dieksekusi/dijalankan secara otomatis. Tapi Anda tetap bisa mengembalikan fitur tersebut ke keadaan semula.

2. USB Drive Vaccination - Virus kini tidak bisa lagi membuat file AUTORUN.inf untuk membantu penyebarannya. Aplikasi ini akan membuat file AUTORUN.inf khusus ke dalam flash disk, di mana file tersebut sudah dirancang supaya tidak bisa diganti, diedit, ataupun dihapus oleh virus. Pengguna juga tidak bisa menghapus file tersebut kecuali dengan melakukan format.

Untuk saat ini fasilitas vaksinasi pada perangkat USB hanya berlaku pada tempat penyimpanan berformat FAT & FAT32, namun ke depannya aplikasi ini akan dikembangkan untuk dapat mendukung format NTFS.

DOWNLOAD Efofex FX Graph v4.000.6

Most graphing packages offer powerful features but they are difficult to learn, difficult to teach and difficult to use. Many schools spend more time teaching students how to use the program rather than actually using it. FX Graph is different - it is dead simple. So simple that secondary students will be using it to solve problems within minutes of first seeing it.

As a quick example, think how long it would take you to draw this graph, with the annotations, in your current graphing package. In FX Graph 3 it takes seconds. FX Graph finds all the points of interest and displays them automatically as you move your mouse around the screen. One click and the annotation is added to the graph. Does simplicity limit versatility? Not with FX Graph 3. FX Graph has a large number of capabilities - far more than we can show you here.

What's Wrong With Other Graphing Packages?

Most graphing packages have their individual strengths but we have identified six common faults.
Fault
FX Graph 3
Setting axes is too difficult. Students find it near impossible to set suitable axes for graphs. FX Graph makes setting axes about as easy as it can be - it can even be totally automatic. Axes that would take minutes to create with other graphing packages can be created in seconds.
Entering functions is too difficult. There are too many "tricks" to learn. FX Graph uses Efofex's equation technology. Equations are entered as the student sees them. There are very few "tricks" to learn.
Finding Points of Interest (maxima, minima, intercepts, asymptotes, point discontinuities, points of intersection, points of inflection) is too difficult. FX Graph automatically calculates all points of interest and displays them when the mouse is close. There is nothing to learn - just move the mouse.
Annotating graphs - adding labels to important points is too difficult or impossible. FX Graph allows you to add comprehensive annotations to graphs with a simple click. When FX Graph AUTOMATICALLY displays an important point, ONE CLICK will turn it into a permanent annotation.
The graphs the package draws do not look like the ones you draw. FX Graph will let you draw graphs exactly the way you want them. Our international focus means that just about every option is available.
The packages are too complex and overwhelming - especially for younger students. FX Graph is designed to be simple to use with a very small learning curve. Thirteen year old, average students will be using it to graph functions in minutes. Eighteen year old, talented students will not find it limiting.

I Already Use FX Graph 2. Why Upgrade?

Because FX Graph 3 has addressed every issue that has been raised with FX Graph 2. Very quickly, the extra things that FX Graph 3 can do include:
More Power - Easier to Use
Implicitly Defined Functions & Conics
Feasible Regions
Constants and Animations
Annotations
Zooming
Points and Vectors
Equal Aspect and Fixed Size scales
Dozens of Other Improvements

As an existing user of FX Graph 2, we will rebate 40% of your existing licence against any purchase.
What Can FX Graph 3 Do?
Graph Cartesian, inverse, conic, implicitly defined, polar and parametric relationships.
Analyse most functions and provide information on important points automatically.
Plot points, groups of points and vectors.
Graph on equal aspect and fixed scale axes
Automatically detect asymptotes and point discontinuities in rational functions.
Show tangent lines and 1st and 2nd derivative curves.
Calculate and display definite integrals including areas to the y axis.
Zoom and graph on broken axes.
Easily annotate your graph using automatically generated text.
Graph inequations and the feasible region for a system of inequations.
Include constants in functions - interactive animations
Produce publication quality graphics with a minimum of effort.
And much more.
There Must be Something to Learn. How do I Get Started?
