Goooooooooooogle tips

What is "Google"?
Definition: Googol
Pronunciation: 'gü-"gol
Function: noun
Google is a play on the word googol, which was coined by Milton Sirotta, nephew of American mathematician Edward Kasner, and was popularized in the book, "Mathematics and the Imagination" by Kasner and James Newman. It refers to the number represented by the numeral 1 followed by 100 zeros. Google's use of the term reflects the company's mission to organize the immense, seemingly infinite amount of information available on the web.
Originally called "Backrub", the logic behind the Google search engine was develop by graduate students Larry Page and Sergey Brin at Stanford University in 1995. Their first place of business was literally a garage. The garage location was chosen because it had a washer/dryer and a hot tub out back, they were already serving 10,000 searches a day.
try this link--
So How Does Google Work?
* Crawls and indexes web pages et al.
* Stores copies of web pages and graphics on their caching servers
* Presents users with simple front end to query the database of cached pages
* Returns search results in a ordered fashion based upon relevancy
Anatomy of a Search
Server Side
Client Side
What Can Google Search?
* Adobe Portable Document Format (pdf)
* Adobe PostScript (ps)
* Lotus 1-2-3 (wk1, wk2, wk3, wk4, wk5, wki, wks, wku)
* Lotus WordPro (lwp)
* MacWrite (mw)
* Microsoft Excel (xls)
* Microsoft PowerPoint (ppt)
* Microsoft Word (doc)
* Microsoft Works (wks, wps, wdb)
* Microsoft Write (wri)
* Rich Text Format (rtf)
* Shockwave Flash (swf)
* Text (ans, txt)
What is "Google"?
So What Determines Page Relevance and Rating?
* Exact Phrase: are your keywords found as an exact phrase in any pages?
* Adjacency: how close are your keywords to each other?
* Weighting: how many times do the keywords appear in the page?
* PageRank/Links: How many links point to the page? How many links are actually in the page?
Equation: (Exact Phrase Hit)+(AdjacencyFactor)+(Weight) * (PageRank/Links)
How Do I Get Results?
* Pick your keywords carefully & be specific
* Do NOT exceed 10 keywords
* Use Boolean modifiers
* Use advanced operators
* Google ignores some words:
a, about, an, and, are, as, at, be, by, from, how, i, in, is, it, of,
on, or, that, the, this, to, we, what, when, where, which, with
Google's Boolean Modifiers
* AND is always implied.
* OR: Escobar (Narcotics OR Cocaine)
* "-" = NOT: Escobar -Pablo
* "+" = MUST: Escobar +Roberto
* Use quotes for exact phrase matching: "nobody puts baby in a corner"
"there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns, the ones we don't know we don't know."
Use Google To Calculate Mathematical Equations
Google adds in new functions in its search every year. A couple of years ago, it quietly added the ability to calculate mathematical equations right from the search box.
If you enter 25 + 35, Google will return 25 + 35 = 60, along with, of course, an option to search for documents that include the term 25 + 35.
To use Google's built-in calculator function, simply enter the calculation you'd like done into the search box and hit the Enter key or click on the Google Search button. The calculator can solve math problems involving basic arithmetic, more complicated math, units of measure and conversions, and physical constants.
Try one of the sample expressions below, or refer to google complete instructions for help in building your own.
These sample queries demonstrate the utility and power of this new feature:
* 5+2*2
* 2^20
* sqrt(-4)
* half a cup in teaspoons
* 160 pounds * 4000 feet in Calories

How To View any Restricted Website with Google
Most companies and schools employ proxy servers to filter unwanted sites so employees won’t waste precious company resources surfing sites that the companies deem unproductive.
One way is to use an anonymous proxy server (such as But once the system administrator learns about this, he will likely block this site as well. A much more foolproof way is to use Google.
3 ways to use google to see restricted sites:
1. An interesting workaround to bypass your proxy server is to use Google Translate to translate the page you want to view from English to English, like this:|en&

2. Another interesting way to bypass it is to use Google Mobile to load a site:

For example:

3. The third technique is to use Google Cache.
Search in your desired website. If you search for in the right of the domain you’ll see the word Cached.
Using this technique, you should be able to view most of the sites you want. The only downside to this is that the content cached by Google might be outdated, and some images may not load at all.

Removing Virus......

folder option Problem
u r pc is infected with some virus or disabled by Someone
may be ravmon.exe

u hav got some tools like RRT to remove restrictions like folder option

download the tool and enjoyyyyyyyy
1.Execute Regedit (shortcut, or StartMenu -- Run, and type regedit ..)
2. move with mouse to menu in Regedit's window and go to Edit -- Find (or simply stroke Ctrl+F)
3. Type HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\E xplorer
4. and finally - find REG_DWORD entry, named NoFolderOptions (if it is there at all, but probably it is) See, if mentioned entry has value 1 ... If it has, simply change it to 0, and that should do the trick
drives don open with doubleclick
The symptom occurs because when autorun.vbs is created by trojan horse or virus.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
Finally, autorun.bat will call wscript.exe to run autorun.vbs.
When antivirus or security software detected the autorun.vbs file as infected, the file will be deleted or removed or quarantined. However, other files (autorun.*) and registry value still referring to autorun.vbs, and this document no longer exists, hence the error when users double
click to open a drive folder. To correct and solve this error, follow this steps:
Run Task Manager (Ctrl-Alt-Del or right click on Taskbar)
Stop wscript.exe process if available by highlighting the process name and clicking End Process.
Then terminate explorer.exe process.
In Task Manager, click on File -> New Task (Run…).
Type “cmd” (without quotes) into the Open text box and click OK.
Type the following command one by one followed by hitting Enter key:
del c:\autorun.* /f /s /q /a
del d:\autorun.* /f /s /q /a
del e:\autorun.* /f /s /q /a
c, d, e each represents drive letters on Windows system. If there are more drives or partitions available, continue to command by altering to other drive letter. Note that you must also clean the autorun files from USB flash drive or portable hard disk as the external drive may also be infected. then in Task Manager, click on File -> New Task (Run…).
Type “regedit” (without quotes) into the Open text box and click OK.
Navigate to the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Check if the value name and value data for the key is correct (the value data of userint.exe include the path which may be different than C drive, which is also valid, note also the comma
which is also needed):
If the value is incorrent, modify it to the valid value data.
whenever u bring a USB from an untrusted source, or u are suspicious, u right click the drive --->explore. This way the trojan, if present wont run. Also, if a drive doesnt open due to trojan, for the time being u can open it by right click drive--->explore. After that u can unhide hidden files and system files from the folder options to search for suspicious files and folders and remove/rename them. In USBs, the trojans come with an autorun.ini/.inf and the trojan program which gets executed by the script in the autorun.ini/inf Lets see wether your system is infected or not... Download HijackThis
Install and run this software
Click "Do a system and save logfile"
There are chances of possible malware present in your system that's why i suggested this software.
desktop_ini Trojan
well this is a nearly harmless virus, i'm also infected with this...........but don't worry do the following go to my computer right-click on C drive and choose serch option enter the keyword u mention & click on search(after enablibg all options except case sensitive from more advanced option) after finishing search select all what the search shows and press shift+del do the same for remaining drives
