Users have to be logged in to their Google account to use SearchWiki |
Google has unveiled a tool that will allow users to customise and refine their search queries.
The company's SearchWiki lets users re-order, remove or add specific web search results.
This means the next time they perform the same search, the personalised version will pop up.
"I would call this revolutionary. It's a huge step, not a baby step in the world of search," Google's product manager, Cedric Dupont, told the BBC.
"This is part of an obvious movement of the web to become more participatory, so Google search is adapting to this movement," he said.
"The SearchWiki is about giving users more control over their search results and increasing user happiness," Mr Dupont added.
But industry watchers predict one huge problem with the effort.
"Most people are not going to engage with it and think about where the results should be - if it's above this one or below that one," said Greg Sterling, an editor with SearchEngineLand.com.
"This is really for a motivated or elite core of user who really wants to participate in the process."
"Social search"
As well as ranking results, SearchWiki allows users who have logged in to their Google account to write comments which will have a dialogue balloon next to the result when they return for any further searches.
These will also be public so that others using SearchWiki can view them and get feedback on a website.
It is hoped "people powered" tools like SearchWiki will benefit overall search |
Mr Dupont stressed that SearchWiki would not affect the way websites were ranked by Google.
At the bottom of the page, there will be a link to take users to a page showing what search results others have re-ranked, deleted or added.
Mr Sterling said that if Google managed to get a great number of people re-ranking results, it could improve the overall search experience.
"Lots of people have tried so-called 'social search', combining algorithmic search with human editorial input, because the perception is that humans have the ability to craft a better result in any given situation because they can make distinctions machines can't," he said.
"So this could be quite dramatic if they get a lot of people participating because it could improve the algorithms of the process and serve up better search results."
Matthew Humphries of geek.com would like to see the tool available to the public at large and not just to account holders. He said that even among SearchWiki users, search would be improved.
"You always see posts on forums for different subjects asking for the best resources to help with X. With SearchWiki the responses won't be a bunch of links, they will be a single link to an annotated Google search page," he added.A flawed signature update to AVG Technologies' antivirus software over the weekend crippled some Windows XP PCs by mistakenly deleting a critical system file, the company has confirmed.
According to messages on AVG's support forums and its own support site, an update released late Saturday for the company's security software fingered the "user32.dll" file as a Trojan horse. As per the program's settings, the AVG software, including the newest version 8.0 and its predecessor 7.5, shut the .dll away in quarantine. The result: A crippled computer.
"If you have chosen 'heal' or 'quarantine,' your PC will no longer restart," said a panicked user named "pa3bar" in a message Sunday. "It shows a blue screen at start up and tells you it cannot find winsvr, error c0000135. System recovery has no effect."
AVG, best known for its free Antivirus, confirmed the error in a FAQ on its support site. "In case you are not able to run your Windows XP operating system after AVG 8.0 virus definition update, it may be caused by a false positive on a specific 'user32.dll' system file," the company said. "The file was moved to the AVG Virus Vault and deleted. Therefore it is not possible to start Windows."
Although some systems refused to boot, others rebooted endlessly instead.
On its support site, AVG posted instructions for affected users that involved running Windows XP's Recovery Console, disabling several AVG services and restoring the user32.dll file by copying it from the operating system's install CD. For users unable to locate their installation disc, AVG offered a utility that fixed the problem; those users also needed to create a bootable CD or USB drive.
The utility work-around was for AVG Antivirus 8.0 only; a similar utility for AVG Antivirus 7.5 will be available "soon," according to a message posted by a support forum moderator Tuesday.
An AVG technical support representative provided more detail on the snafu. "We can confirm that it was a false alarm," said Zbynek Paulen, who identified himself as an AVG employee. "We have immediately released a new virus update (270.9.0/1778) that removes the false positive detection on this file. Please update your AVG and check your files again."
That suggestion, however, only worked if the user had not turned off his or her PC, or rebooted it, in the meantime.
"We are sorry for the inconvenience," Paulen added.
AVG did not publicize the problem on the front page of its Web site and did not immediately respond to several questions, including how the flawed signature slipped through internal checks.
This wasn't the first time that AVG has been in the spotlight. Last summer, the LinkScanner Search-Shield component of its antivirus software triggered a flood of bogus traffic to Web sites, angering site operators.
Nor is AVG the only security vendor to issue a damaging update. Only last September, a Trend Micro Inc. signature mistook several critical Windows XP and Vista system files for malware, blocking the PCs from booting.
