Recovering Complicated Hidden Files

Image
There was a time when I had on my hands a USB memory which was supposed to be infected by a virus, and looking at it I realized that this malware had been erased many folders and files, but I first tried to see if they were only hidden. Let's suppose that this was the USB file structure, with no virus.   Once the virus infected the USB, the situation changed into this. As you can see, there was no files inside, but going to the folder properties we could look at the line that it actually had 1 file and 1 directory. Once the virus infected the USB, the situation changed into this. As you can see, there was no files inside, but going to the folder properties we could look at the image that it actually had 1 file and 1 directory. The next thing I did was to show all hidden files but it didn't work, so I disabled the "Hide protected operating system files (recommended)" option , having as result this. Therefore, the virus hadn't erased them, but only hidden them, 

Mount a Disc Image on Your PC

Image
First at all, I consider important to explain what is a disc image, this is a file which contains information of a CD, DVD or Blu-ray even, having inside the structure of the disk, files and data that is used to execute it without problems. This image can be saved on a lot of formats (.iso, .ccd, .cue, .nrg and more) and it gives the chance to use it on a PC without the necessity of burning it into a physical disc. As it allows to do so, I use this feature many times to verify if a movie DVD has been built correctly to burn it into a disc later. For this purpose we will use Daemon Tools Lite to mount the image to be recognized by the PC as if it were inside the CPU physically. This effect will be reached because the tool creates a virtual CD/DVD device where the image will be mounted. After installing this tools, you will notice the new CD/DVD devices that will appear together with you other devices, then you run Daemon Tools Lite to get it in your task bar beside the clock.   Onc

Running Applications as Administrator on Limited User

Image
I always considered that having a safe computer is a matter of how much privileges a user has on the operating system, therefore my idea every time, when I'm in charge of a computer, is to create a user as a limited one instead of creating it with administrator privileges. The administrator role is thought to be used only for administrative tasks such as installing applications, cleaning the register and so on. What is more, this role is used to install malware on the computer, and this is why it's necessary to only permit the use of limited users to avoid problems. However, I realized that there are applications that only can run under administrator privileges, for instance, games, this can be done by using the "Rus as..." option located in the right-click menu but this require the presence of the administrator.   To not force the administrator to be present in the execution moment exists Runasspc   that allows you to create an encrypted file containing the path o

I Need to Send an Automatic Email with Lotus Notes

Image
If you don't know, Lotus Notes is an email client used in a lot of companies around the world. Therefore, I use it at work everyday, but someday I needed to send an automatic email to a few people all Fridays at 10:00.   To get this task accomplished I decided to create an agent and avoid remembering the fact of sending the email. As you can image, I did this example on a Spanish version of Lotus Notes 8.5 but I will explain it clearly enough. The first step is getting yourself into the inbox, then select the "Create" menu item and inside of it, click on "Agent...". You will get a dialog box opened, in this we have the possibility of setting the rules for this agent. However, in this case we will only set "Trigger" option to "On schedule" with the "Weekly" frequency. Don't forget to push the "Schedule..." button to program the agent in the right way. After this, select "OK" and close the dialog bo

Conditional Lists on Excel

Image
Working everyday gives you always a number of problems that you have to face it, and it was my case when I needed to make a list on excel to select a value that modifies a next list depending on the value selected. The way I solved this inconvenient will be shown here with a simple example: there's a list of 3 countries and depending on the selected one, the next cell must show a list of some cities to be selected. Despite the example is performed in Excel 2010, I think that you can apply it even on Excel 2003. Before beginning it's necessary to create a sheet which will contain our data base with the countries and the city-country relationship, then, we have to group the cities of a determined country in a named range. To do this, you only select the cities for Australia, for instance, and go to the cell that is on the left of the function bar and type there the name of the country and press Enter, thus, for every country. Having the respective named ranges, go to the tab w

Copying .cda Files to PC

Image
It happened to me when I wanted to have CD tracks in mi PC rather than in the CD itself, I thought at that moment that copying all .cda files from this CD to mi PC would be enough, but it wasn't. Then, I believed that it would be easier to have this track in MP3 format, so I made a little research I discovered that Nero could help me with this mission. Perhaps, the latest version of Nero will show more options, however I consider that it keeps the similar procedure explained here (based on Nero 9). Open Nero Burning Rom application through Start menu and this window will appear. You have to close the previous window to keep only the main form, where you are going to select the "Save Audio Tracks..." from the "Extras" menu item. After this, the program will read all tracks which are contained into the CD, here you are asked for the tracks you want to convert to MP3. Before starting the copying process you need to go to the "Output" tab, which is n

What If I Don't Like Paypal?

Image
There could be people who don't like Paypal , por instance, when I realized that Paypal account for my country didn't allow money to get received I felt really disappointed. Therefore I decided to look for an alternative, and actually that was what I found. I'm talking about  Alertpay which gave me in the past the opportunity to get paid with electronic money, it's very similar to Paypal so let's go straight to the account creation process. First at all, go to the page and click on "Sign Up Now". Then it's moment to select the country and the type of account we are looking for. The site will show a form which is required to be fulfilled. After a few minutes you will have to validate your email and later your Alertpay account will be created. Once you have access to your account don't forget to link it with your credit card to assure that you are able to make operations between AlertPay accounts. For this, you need to go to the "My Accou
