Below is a complete definitions about Viruses types and Spywares:
>> Normal Virus?
A virus is a computer software that spread itself into copies in a computer via a network or via the Internet.
It might comes through an attachment, or infected files from different Medias, and it won’t be activated unless you run the infected file or attachment.
>> Spyware?
A spyware is software designed especially to gather your information and report them to someone else via Internet.
Usually spyware comes from the Internet by visiting a specific websites; it might come by your permission indirectly (like a website asking you to download an antivirus software for free or another software normally from a pop up window) or it might be downloaded without your consent.
They might affect your computer speed or your Internet connection speed, they might change your internet home page…etc.
Not all the antivirus programs can detect spywares, so for better protection use a dedicated antispyware program and keep it updated.
>> Adware?
Adware is software which displays advertisements on your computer.
Description:
Shows advertising banners and pop ups.
Attaches itself to the Internet browsers to display the advertisements.
It work like Spyware, hence taking information from your Internet Browsers and send them to another ones (through internet).
Slow down your Computer speed and your Internet connection speed.
>> Backdoor Trojan?
Backdoor Trojans are software allows someone to take control of another computer through the internet without permission.
Description:
The Backdoor Trojan used to be sent by the Hackers in order to connect their computers to the victim’s computer and to take a full control of the Victim’s one, like they can steal all your personal and confidential information, they can install or uninstall software on your PC, they can send emails from your own Windows, they can perform restarts or shutdowns to your Windows etc...
The problem with the Backdoor Trojan is whenever you connect to the internet it will try to connect to the Hacker’s computer, because once its created it adds it self to the Windows startup routine which means every time you open your PC , it will be initiated automatically.
From where those Backdoor Trojans come?
Backdoor Trojans are activated and installed on your system by you!! You would be wondering how come by me? Its real , because the only way to a virus to be activated and to start working on your computer is by double clicking the infected files… the infected files might be pictures, programs installation files, crack files, Macros, movie files and so on.
>> Spam?
A Spam is an unsolicited commercial email.
This email normally comes into your inbox from different unknown email addresses and normally they have different subjects like (how to be rich?) or (learn languages in 1 day) or commercial subjects, sometimes they have a friendly way subjects like (Re: My reply to you.) or (Remember my advice…) or sometimes they come to you as you won a prize like (Congratulations you are the winner!! You’ve just won 1 million dollar...)
All of the above are simple examples about spam emails which usually either they want to promote a product, or they want to steal money from you…
How would they steal money?
Some of the spam email senders try to fool you that you have won million of dollars and will send you the money, or that they have a lot of money Inherited from their father in another country (which sometimes they give you a huge amount like 10 million dollars) and they need your assistant to transfer their money to their account in their country, and they will send you a percentage of that money as a commission for your transaction, but they tell you they need you to send them the money transfer transaction charges in advance (which sometimes they ask for about 200$ or more) to their address in order to transfer your commission, so once you send them the money you will never hear from them anymore (so don’t let anyone fool you)
>> Trojan horses?
Are programs that perform harmful activities in a legitimate face.
Trojan files are so dangerous because they seems to be normal software when you run them while they are performing another activities in the background like stealing passwords or confidential information or even to make problems to your system, basically those Trojans come via the email, or by using the crack files.
>> Boot Sector Virus?
Boot Sector Viruses are software that starts spreading by changing the program which leads your PC to startup.
Description:
The boot sector is where the computer looks into it in order to start initiating the hardware and then to complete loading the Windows into the computer memory.
The Boot sector virus will replace the small program in the boot sector with the infected one in order to be activated every time you start your PC, this virus normally comes from a floppy disk, flash memory, CD/DVD or the Internet.
