This command syntax is for limit the searching that only gives you result that has information in a topic that you mean.
For example: intitle:global warming
Google will search the page that has global as the title with warming as the main priority. If the searching has two main searching queries, use the syntax allintitle:global warming and searching will be limited by two main subject, that’s global and warming.


2.inurl:...

This command syntax is for limit the searching that only gives you result that has your keyword in all URL. Example: inurl:database.mdb
The searching will display all URL that has information about database.mdb.If the searching has two main searching queries, use the syntax allinurl:… to get the list of its URL. Example allinurl:etc/passwd, the result will display to you all URL that has information about etc and passwd. Slash between two word will be ignored by Google.

How To Use Google ( Part 1 )

on

At this time I want to give you some tips how to use Google as well as correctly (just the basic), in order you can get your information that you find quickly.



First, use the excerpt mark “……” You can use this mark to find a blog or website that has a sentence that you mean. Example you want to find Modern Technology, You can type it “Modern technology”. If you type like that, Google will display to you all blog or website which has a modern technology sentence. But if you just type Modern Technology (without excerpt mark), Google will display all blog and website that has Modern and Technology word and Modern Technology sentence. Which one is effective? I suggest to not writing a long sentence because you will find nothing from Google.



Second, you can use the mark + and - (plus and minus). These marks are very useful to find some article. I can’t explain to you how to use it, but you can understand if I give you an example. If you type Hotel + London, Google will give you all information about hotel in London. If you type Hotel – London, Google will give you all information about hotel but without information from London’s hotel. You can combine these marks too. Ex, America + Bank - City Bank, Google will give you information about all banks in America without city bank.



Last, if necessary you can combine those two ways above. Example, you want to find Modern Technology in America Hotel without Information from Hilton Hotel. You can type “Modern Technology” + America + Hotel – Hilton Hotels.

What is computer virus?

Computer virus is program that wrote from “low degrees language” like ASSEMBLY which has an ability to spread itself from a program to another program. A computer virus is not same as the disease virus because the computer virus is unshaped. It named computer virus becauseof it has ability like disease virus that can spread itself and commonly its detriment. Computer virus usually made by a software specialist especially for the specialist who understands about ASSEMBLY language and ability to understand an operation system. Butnow there are many viruses that make from the high language like MACRO and etc.




How the viruses can spreads itself?

The virus just can spread itself if we activated it or if we executed it. So it’s impossible for the virus to spread itself by ASCII file and it’s impossible if the virus infect your computer because of the there is a disk with virus in it without execute. And because of that the virus spread itself from the files that usually execute like: .com, .exe, .bat, .ovl, .Drv, and etc. to spread itself, the virus usually spreads itself by execute file and we always cheated with that file.

We have to remember that the virus (computer virus) is not “something life” like disease viruses that we know which can be spread by air or the other media. The virus is same as with the other programs where it will active if we execute it. So it’s impossible if the virus can be active without execute and the virus always be the execute file. The virus can’t spreads by a file that not executed, like text data and etc. but you have to remember that the virus can break anything in your computer except hardware. There is no virus that can destroy hardware like monitor, keyboard, mouse, and etc.




Can all people make a virus?

When we will make the virus, we need much knowledge especially about “low degrees language” and the knowledge about operation system. So for the common people it’s so hard to make a virus but it’s possible for the common people to learn how to make it and learn how to anticipate the virus. For the virus that make from “high degrees language”, that’s easier for the people to make the virus without know ASSEMBLY language. You just need only the knowledge that always keeps in your secret.

Until today there is no antivirus that can prohibit the entire virus that spread. That’s because each virus has different work. So to prohibit the virus, the antivirus have to know first how that virus work.




Is it possible if the antivirus be the spreader?

Actually antivirus program is a program that can be infected by the virus. If antivirus was infected by the virus, the antivirus will be the spreader of the virus and it will spread the virus to the other program or the other computer. I suggest you to always save your original antivirus in a clean disk. You have to know that there are antiviruses that can check and clean itself from the virus.




What does the virus usually do?

Nobody knows what the virus usually does really because it’s depend on of the maker of virus. Maybe the virus will display a message or maybe it just duplicates itself. There is also the dangerous virus that can damage your computer system or take your secret data like code. We can say that all of the virus can’t give us advantageous.




What should I do if my computer was infected by the virus?

The first step is don’t panic and backup your important data, but don’t backup the infected data. The second step is try to know the variant of the virus and use the antivirus. Carry on to using local antivirus. Last, if you can’t find the virus, you just can reformat your hard disk with system disk that clean from the virus and reinstall all of your application.




How to keep my computer from ant virus?

You can’t make your computer free 100% from the virus. But there is some tips to keep your computer not infected from the virus:

1. Computer virus is usually spread from the disk or flash disk that use by some computer. So keep watch if you use disk or flash disk together.

2. If you want to install program, make sure that the program is original and have protect or find the installation from CD/DVD.

3. Don’t late stranger person use your computer.

4. Don’t take strange program from the internet.

5. Don’t use anything game, because the game usually is the good media for the virus to spread itself.

6. Use the antivirus program to detect the virus.

7. Always update your antivirus, because the new antivirus always has information from the new variant virus.
