A Virus Program to Disable USB Ports
In this post, I will show how to create a simple virus that disables/blocks the USB ports on the computer (PC). As usual, I am using my favorite C programming language to create this virus. Anyone with a basic knowledge of C language should be able to understand the working of this virus program.
Once this virus is executed it will immediately disable all the USB ports on the computer. As a result you’ll will not be able to use your pen drive or any other USB peripheral devices on the computer. The source code for this virus is available for download. You can test this virus on your own computer without any worries since I have also given a program to re-enable all the USB ports.
Download the USB_Block.rar file on to your computer.
1. It contains the following 2 files:
block_usb.c (source code)
unblock_usb.c (source code)
2. You need to compile them before you can run it. A step-by-step procedure to compile C programs is given in my post - How to Compile C Programs
3 To test this virus, just run the block_usb.exe file and insert a USB pen drive (thumb drive). Now you can see that your pen drive will never get detected. To re-enable the USB ports just run the unblock_usb.exe (you need to compile unblock_usb.c) file. Now insert the pen drive and it should get detected.
4. You can also change the icon of this file to make it look like a legitimate program. For more details on this refer my post – How to Change the ICON of an EXE file (This step is also optional)

How it Works?
The idea behind the working of this virus is pretty straightforward. It works by gaining access to the Windows registry and modifying it’s settings to disable the USB device support on the computer.
On the other hand, the other program will re-set the registry settings back to the normal so that the support for USB devices is re-enabled. I hope you like this post. Please pass your comments.

Increase Adsense eCPM

eCPM stands for “Effective Cost Per Thousand of Impression”. The eCPM can be computed by dividing the Adsense Revenue by the Adsense Impression and the quotient will be multiplied by 1000. The process can be presented by the mathematical formula:
eCPM = (AR / AI) * 1000
Where: AR stands for Adsense Revenue and AI stands for Adsense Impression.
In other words, the Adsense eCPM is totally dependent to the Adsense CTR and CPC.
By just considering the formula given above, we could already say that the higher in Revenue and lower impression will result to higheCPM. And on the other hand, the lower the Revenue and higher impression will result to low eCPM.
But, let’s say that the impression is constant in two different periods but the Revenue varies from one period to the next period.
For example, the generated impression is 1000 in day-1 and in day-2; and the revenue is $10 in day-1 and $5 in day-2.
By substituting the data to the formula given above, the result will be $10 eCPM in day-1 and $5 eCPM in day-2.
The result simply tells us that if you could not increase the number of impression of the Adsense ads, you need to increase the eCPM of Adsense by simply working for the increase of the Adsense Revenue. However, in a constant impression, Adsense Revenue greatly depends on the CTR and CPC of Adsense.
How to increase the Adsense eCPM?
In other words for you to increase the eCPM what you need to do is:
1. Increase the CPC of the Adsense ads. Just imagine if a click in your Adsense is worth $10, which means that in just 1 click in your Adsense you already earn $10. Now, what if there are 3 clicks generated in your Adsense. Well.. That’s really very interesting especially if your Adsense CPC is as high as $10 per click because in just 3 clicks you already have earned $30.
2. Increase the Adsense CTR. Again, imagine what would be your income if your Adsense have CPC of $10 per click but no one click your Adsense ads. So, you earn nothing even if your Adsense has better CPC.That simply tells you that the Adsense CTR really affects your Adsense income. The more your Adsense receive clicks, the more you earn from Adsense.
3. Avoid being Smart Priced by Google Adsense. Smart Pricing is another thing that makes your Adsense earning to drop. Google Adsense implement Smart Pricing to protect its advertisers and help them increase the ROI.
4. Remove ads from pages with very low eCPM (not necessarily CTR though)
5. limit the number of adblocks per page.
6. make the content on the pages as easy to target as possible with all the usual “spider food” SEO stuff, page titles, page names, descriptive original content,etc.
7. try a 336×250, above the fold, centered in the content, or a leaderboard
8. blend the ads in as naturally as possible.
