[HowTo] Open thumbs.db and extract thumbnails from it

Thumbs.db is a file used to store thumbnail data of a folder in Windows. It makes loading of thumbnails significantly faster, however it has some privacy issues. Like if you delete an image, its thumbnail might still be there in thumbs.db file which would allow you to view it.

There’s an open source python script called Vinetto available to extract all the thumbnails in open.db to a folder. It works on Linux, Windows and Mac OS. You can download the script from here.

On Ubuntu, you can use apt-get to install vinetto:

sudo apt-get install vinetto

To extract thumbnails:

vinetto -o ./thumbnails ./thumbs.db

This will extract all the thumbnails inside thumbs.db to thumbnails folder.

Cheers!

[How-To] Change default application installation location on windows xp

So, you just want to keep a partition for Windows XP and another partition for all your applications that you install. You can change it in all the installations manually but changing the default location is a much better idea. And there are also some applications which don’t let you change the default path.

XP uses the C:\Program Files directory as the default base directory into which new programs are installed. However, you can change the default installation drive and/ or directory by using a Registry hack.

Run the Registry Editor (regedit)and go to

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

Connecting to a windows computer on LAN using Samba

Well, you would consider this to be very difficult task to accomplish but it wasn’t. It was confusing at first but once you know what you got to do, its really simple.
Samba is the application you need for this purpose. To install samba type:

sudo apt-get install samba4

in terminal and enter your password to download and install samba. Installation could also be done using Synaptic Package Manager.

Windows Vista had changed the way it authenticated users. It was different from windows xp. Samba wasn’t able to able to share files with windows vista due to this reason but it has been solved since Samba3.

Okay, getting back to the topic..

You also need smbclient to surf the windows shared files on the network. Install that by typing the following command in terminal:

sudo apt-get install smbclient

This will install the smbclient. To browse the shared folder, you can just go to Places->Network->Windows Network and find all the shared computers there. If you don’t see the shares there, don’t worry. I wasn’t able to see as well, so I typed smb://192.168.1.2/ in the address bar of any file explorer, where 192.168.1.2 is the ip address of the windows vista computer.

To share files from ubuntu to windows, just right click on a folder, then click on properties. Click on share and select the ‘Share this folder’ option. It may ask you to install some services. Click on yes to install them. After installation, you’ll be able to browse the folder on your windows vista like a normal windows computer.

The guide may have some errors. Pardon me if thats the case. Remember, I am just a newbie. This did work for me, though.

Cheers!

Edit registry without windows

Many a time you will want to edit your registry when you get your windows screwed and it refuses to boot up.
You know what changes should be made in the registry to fix the problem, but you don’t have any way to fix it. I had a similar problem and I used this tool to edit registry:
http://home.eunet.no/pnordahl/ntpasswd/main.html

This is a non-GUI bootable app. You should be familiar with the command-line and how it works before using it otherwise you may get into deeper problems.

This is another tool which I found while googling:

I hope this helps all you people who are thinking to reformat your computer because of registry errors.

Peace!

[HowTo] Remove almost any kind of viruses from Windows

Being attacked by many viruses in the recent times, I thought why not make people learn from my experience. Having faced about a dozen of different viruses in past 2 weeks, I have experience enough to write this guide. I faced trojans, trojan downloaders, rootkits and what not. So here’s my little guide which will help you get rid of your virus.

We’ve got a huge amount of viruses floating over the internet. New viruses are being made by evil programmers daily. Due to this innocent computer users are being infected and suffering from infected system which results in compromising of private data, destruction of data, unusability of computer etc. For non techy people virus removal is a tough task. Fortunately, for tech-savvy people its not so difficult.

I am writing this guide so as to help people from removal of viruses from their computer.

A brief introduction about viruses. A virus is generally a malicious software which tries to steal personal information from your computer or uses your computer for other malicious activities like spamming, used as proxy from illegal activities, spreading malware etc.

Computer can be infected from virus through many means. You can get infected from a mail you opened from unknown person, some software installation, a friends pen-drive which you just inserted in your computer etc.

Until now, only Microsoft Windows have been known to be infected by viruses. Linux and Mac OS remains unaffected. There are only few known viruses for them. Windows on other hand has thousands of viruses with new viruses being produced everyday.

To protect yourself from viruses you will need to have good combination of security tools.
Tools required:

1. Sysinternals Process Explorer.
2. Good anti-virus software (preferably Kaspersky, NOD32, or Norton).
3. Malwarebytes Anti-Malware
4. Registry Fix.
5. Task Manager Fix.
6. UnHackMe.
7. Lavasoft Ad-Aware latest 2009 version. (Older version has many drawbacks)
8. HijackThis
9. Spybot S&D. (Optional)

Most of the viruses won’t let you know when they install themselves on your computer. You won’t even notice them unless they do something noticable like use internet extensively which draws your attention etc.

When you get infected by a virus and you are sure about it:
You know that you have been infected by a virus and you don’t know what to do. Just bear with me and you will find quick solutions to your answers.

To check if virus is using the internet:

1. First of all check if it is using internet. Go to Start Menu-> Run -> Type “cmd” without quotes and enter.
2. Then type “netstat -b” without quotes in the console and press enter.
3. On the left hand side, you will see a list of executables and right to that, you will see the sites it is connecting to. If you see any unknown executable connecting to any unknown site. It means that it is using your internet. In this case, I recommend disconnecting from internet to protect yourself.
