Difference Between Virus,Worms,Trojan and Spyware

We all have heard the terms Virus,Worms,trojans and spyware but only a few of us know the difference between them.We genreally consider everything that is detected by an antivirus as virus but this is not the case.The antivirus not only provides protection against viruses but it also protects us from trojans,worms and spywares.All these can be harmful to your computer hardware and software.Today I will differentiate all these terms from each other .

Ok lets start from the introduction of viruses

Virus :- A virus is a self replicating program that attaches itself to an executable file.When the file is executed the virus automatically gets executed and enters into system memory .Once it enters into system memory it either searches for other files that can be infected or stays in the background and infect the files that are uses the virus infected program.

Worms : Worms are very similar to viruses but differ in way that they donot bind themselves to executable files instead to replicate themselves they uses the network.If you find excessive use of your network bandwidth then you may be infected by a worm.So,a worm donot require a user to execute any file for its execution it can work without user intervention.

Trojan Horse :- A trojan horse is harmful program which may seem harmless to the user before its installation but instead it is programmed or reverse engineered to facilitate unauthorised remote access to the computer.Trojan’s donot replicate themselves.

Spyware :- A spyware is a program that secretly monitor and collects pieces of information.They usually run in stealth mode and cannot be detected easily.Keyloggers is a great example of spyware software.These are not limited to just spying but can also send data to remote computers .

Increase Internal Memory of Samsung Galaxy Y

1.  You will need to root your Samsung Galaxy Y.
2.  We need to create a partition on your SD Card or your microSD card.
3.  To create a partition in our microSD Card, we will be needing a free tool called MiniTool.
4.  After you have download the MiniTool Partition Wizard, install it in your computer and Run MiniTool.
5. If your microSD card is new then you can proceed with creating a partition. If not, be sure to back up everything in your microSD card. Creating a partition will delete every data in your microSD card.
6.  Plug your microSD card to your computer. While in MiniTool, right click your microSD card drive and format it. REMEMBER: Be sure it is the correct drive and do this after you have backup every data in your card. Select fat32 as file system, hit ok and hit the apply button found in the upper left corner of MiniTool (the one with the big blue check mark)
7. After you have formatted it, right click on the microSD drive again and select Move/Resize.The unallocated size will serve as the additional internal memory of your android smartphone. Hit ok after you have set the partition size.
8. You will see in the MiniTool window an unallocated size in your microSD card.. Right click and create a partition for it, it will be formatted at the same time. Choose EXT3 as its file system. Hit the Apply button again after. Again be sure to hit the big check “Apply” buttonotherwise the changes would not be implemented.
9. After partition, you will only see the FAT32 portion of the microSD in your Windows Computer. But in Minitool you will see that there is a FAT32 and EXT3 partition. Now your done with the partitioning.
10. You will also be needing another app called link2sd.
11. Install link2sd in your smartphone, run link2sd and it will ask you to mount script. Choose ext3 and hit OK
12. After you have successfully done that, reboot your android smartphone.
13. Once your phone returns from reboot, Run link2sd, go to its settings and check everything to auto-link. That should do it!
