Unlock System Volume Information Folder

There is a folder in you each drive of computer, in Windows OS, with the name of "System Volume Information". This folder is usually not accessible and locked. So here you can hide some file so that other people get rid of it.

Caution: Beware, Don't delete important files!
In the following image you can see the System volume information folder.














Procedure:-
This folder is Supper hidden so that you can see what is in it. To make it visible go to "Folder Options" and then Click on "View" Tab. After that Uncheck the option "Hide protected operating system Files (Recommended). After all this if your computer is still not showing that folder then you PC might be infected.

Normally after unhiding this folder, you can't open it because its locked and you see this error.









Now I will tell you that how to unlock it and then place some files in it then lock it again so that an ordinary user cant see it.
Second interesting thing about this folder is it's properties.
























As you can see it's size is zero and contain zero file and Folders. But is not acctually.
Lets unlock it and then see what is in it?

Open cmd or make a batch file and past this. Here I m unlocking D:\Drive. But keep in mind
Here "Administrator" is the current username you can change it if you don't have administrator account.

Unlock:-
cacls "D:\System Volume Information" /E /G "Administrator":F
Now you can see the files of System Volume Information. See this image.











And now you can see it's also showing properties.




















And last step to Lock that folder again Past that code in command prompt or make batch file.

Lock:
cacls "D:\System Volume Information" /E /R "Administrator"
Now, S.V.I. is restored to it's default state and again inaccessible.

'State of the Internet' assessed

Internet attacks came from 201 different countries in the second quarter, up from 68 countries in the first quarter, according to a report released Thursday.
Among the 201 countries now seen as the source of malware and other Internet threats, the U.S., China, and South Korea accounted for more than half of the attacks in the second quarter.



















Hyy!! where is Pakistan?

Blaming the Conficker worm on the majority of the assaults, Akamai discovered attacks on 4,100 unique ports, with 10 specific ports hit in about 90 percent of the cases. One specific port, 445, used for Microsoft Directory Services, has proven especially vulnerable and was compromised in 68 percent of the attacks, allowing hackers to invade computers with this port open, Akamai said.

The report also examined connection speeds.

Several countries saw their connection speeds drop from the previous quarter, with the overall global average falling 11 percent to 1.5Mbps. Only 19 percent of the connections throughout the globe managed speeds greater than 5Mbps, a slight decline from the prior quarter.






















Among all countries, South Korea came in first place with an average speed of 11Mbps, while Eritrea was last at 42Kbps. The U.S. was 18th on the global list, reaching average connection speeds of 4.2Mbps.

Akamai found that within the U.S., many states also saw connection speeds fall. Arizona's average speed dropped 27 percent from the first quarter. New Hampshire enjoyed the fastest connection in the country at 6.4Mbps, while Delaware fell to second place at 6.3Mbps, down from 7.2Mbps in the prior quarter. Overall, the East Coast led the nation with the fastest speeds of any region.
















Akamai caches Internet content for its customers, allowing it to monitor traffic through the Net. The company uses the data from its Internet monitoring to compile its quarterly reports.
