If your computer or flash disk is exposed to the virus and we cleaned after the fact that many hidden files (hidden) then can be done the following steps to restore the files that are hidden appear again.
1. Open the Start Menu, go to the run (for those who often use cmd directly into the command prompt and follow the steps 3)
2nd Type cmd and press ok
3. After the show cmd, type flash disk drive where you installed. If the type G in G: and press enter after that
4. Type the command attrib-h-s-r *.* / s / d and press enter
5. Wait a while until the process is complete and appears G: \>
6. If the process is complete, then please see the file on the flash disk by using windows explorer. Hidden file that will appear again

Waspadai Autorun dari Media Removable anda
Hal ini biasanya terjadi jika pada suatu PC atau Computer anda belum terinstall antivirus ataupun sudah terinstall namun belum terupdate. Untuk itu penulis memberikan tips-tips antara lain:
1).Mula-mula perhatikan terlebih dahulu apakah media portable tersebut autoplay atau tidak. Nah, kemudian perhatikan lagi gambar dari media portable tersebut. Normalnya biasanya bergambar media removable, namun jika bukan, anda diharapkan agar lebih waspada lagi dikarenakan hal tersebut biasanya media removable atau kita biasanya menggunakan flashdisk atau hardisk portable kita tersebut sudah terjangkit oleh virus. Lalu jangan sekali-sekali anda membuka flashdisk anda atau media yang lain menggunakan :
start --> My Computer
Namun kita diharapkan agar membukanya menggunakan:
Tekan gambar windows(jendela) pada keyboard bersamaan dengan "e". Windows+e
Atau kita dapat menggunakan cara lain yaitu klik kanan pada start dan klik explore
Kemudian jangan terburu-buru untuk mengklik media flashdisk anda, klik kanan terlebih dahulu pada media tersebut dan lihatlah apakah kata-kata "Autoplay" terletak di pilihan paling atas atau tidak. Jika iya, maka jangan sekali-sekali anda men-double click media tersebut. Jika anda melakukannya, maka virus yang berada pada media tersebut akan jalan dan melakukan proses penyebarannya pada komputer anda. Jika anda ingin membuka media anda, anda dapat mengklik pada icon media anda yang terdapat di daerah pohon program komputer anda (Yang terdapat lambang (+) dan diklik maka biasanya menjadi (-) dan isi media akan menunjukkan (+) lagi).
Lalu kita lihat lagi pada posting sebelumnya, posting yang dilakukan oleh Bu Lintang tentang bagaimana cara mengembalikan file yang telah disembunyikan oleh virus. Nah, lakukan proses tersebut pada media removable anda karena hal tersebut akan menampilkan seluruh file yang ada termasuk juga virus yang tersembunyi.
Nah, pastinya kita akan melihat file dengan nama "Autorun.inf". Segera hapus file tersebut jika anda merasa takut untuk menjalankan virus tersebut ataupun jika anda ingin mencoba untuk melihat di mana letak virus tersebut, edit autorun tersebut dan lihat isi dari file tersebut. Jika file tersebut tidak terenkripsi, maka kita akan dapat membaca di mana virus tersebut terletak.

JIKA DOWNLOAD FILE BERMASALAH
Communicate via email, often have a file that is attached and can be a problem if the attached file can not be downloaded.
It is important to consider if this happens is leveling settings in Internet Security.
Where is the location of Internet Security?
Internet Security is a part (tab) from the Internet Properties / Options in the Control Panel
Next Step
Clicking on the button Custom level .. will show the Security Settings window;
next settings in the search box in the menu settings on the Downloads level below it there is the File menu Download;
Here there are usually tersetting Disable it must be so Enablekan file downloads can be done.

HSDPA
HSDPA, short for High-Speed Downlink Packet Access, is a new protocol for mobile telephone data transmission. It is known as a 3.5G (G stands for generation) technology. Essentially, the standard will provide download speeds on a mobile phone equivalent to an ADSL (Asymmetric Digital Subscriber Line) line in a home, removing any limitations placed on the use of your phone by a slow connection. It is an evolution and improvement on W-CDMA, or Wideband Code Division Multiple Access, a 3G protocol. HSDPA improves the data transfer rate by a factor of at least five over W-CDMA. HSDPA can achieve theoretical data transmission speeds of 8-10 Mbps (megabits per second). Though any data can be transmitted, applications with high data demands such as video and streaming music are the focus of HSDPA.
HSDPA improves on W-CDMA by using different techniques for modulation and coding. It creates a new channel within W-CDMA called HS-DSCH, or high-speed downlink shared channel. That channel performs differently than other channels and allows for faster downlink speeds. It is important to note that the channel is only used for downlink. That means that data is sent from the source to the phone. It isn't possible to send data from the phone to a source using HSDPA. The channel is shared between all users which lets the radio signals to be used most effectively for the fastest downloads.
The widespread availability of HSDPA may take a while to be realized, or it may never be achieved. Most countries did not have a widespread 3G network in place as of the end of 2005. Many mobile telecommunications providers are working quickly to deploy 3G networks which can be upgraded to 3.5G when the market demand exists. Other providers tested HSDPA through 2005 and are rolling out the service in mid to late 2006. Early deployments of the service will be at speeds much lower than the theoretically possible rates. Early service will be at 1.8 Mbps, with upgrades to 3.6Mbps as devices are made available that can handle that increased speed.
The long-term acceptance and success of HSDPA is unclear, because it is not the only alternative for high speed data transmission. Standards like CDMA2000 1xEV-DO and WiMax are other potential high speed standards. Since HSDPA is an extension of W-CDMA, it is unlikely to succeed in locations where W-CDMA has not been deployed. Therefore, the eventual success of HSDPA as a 3.5G standard will first depend upon the success of W-CDMA as a 3G standard.
