Solution for "Bom Sabado" virus in orkut

Google’s social networking website Orkut has been attacked by virus called “Bom Sabado” on Saturday morning, which is a big treat for orkut . “Bom sabado” is a Portuguese world it means “Good Saturday” in English.
Bom Sabado is an orkut virus affecting profiles of many. Those who are affected by this virus are advised to change password and security question. Log out immediately and also clear the cookies and history.Users are also advised not to open Orkut account until the problem solved. Orkut had just last month announced new updates to the website. It’s a second time Orkut got affected by this kind of viruses. The same virus has hit Orkut last Feb also.


A few hours back, the Bom Sabado virus seems to have started and now it is all over orkut scraps that spreading from friend to friends. It is an auto generated message which is filing your scrapebooks. The scraps come from the friend list and it comes just like any other normal orkut scraps. Users are also advised not to open such scraps. The bug is hitting your cookies and automatically sending messages to your friend list.
If anyone reads this scrap even in their profile, their cookies are also stoled and so they are also posting scrap automatically to their friend list same scrap as bomb something like.
Orkut officials have not clear yet that the Bom Sabado is a virus or not. In week, this is a second XSS attack on a social networking website. The popular microblogging website Twitter was also attacked by a computer worm created by Norwegian. Twitter was received an XSS exploit, the attack, which emerged and was shut down within hours Tuesday morning and involved a XSS flaw that allowed users to run JavaScript programs on other computers.
So do not login to your orkut account,
If you want to change password, use this link www.google.com/accounts/
Solutions:-
Do not visit any profile on Orkut till this script is blocked
Clear your cookies and cache right away and change your password and security question:
Another solution :-
I have already posted a solution at many blogging sites. For everyone whose orkut account has been affected with the %u2018bom sabado%u2019 worm %u2026. The worm injects a hidden iframe containing a malicious javascript http://tptools.org/worm.js [do not click this], which steals the user cookie which contains the password in an encoded form. So the attacker do not get to know your plaintext password but can login using your credentials by impersonating using the cookie to fool the identification system. So a trivial solution is to diable javascript, another solution is to disable iframes or u can take an advanced measure by blocking the domain http://tptools.org/ by editing your hosts file and redirecting it to a safe address, say 127.0.0.1 go to C:windowssystem32driversetc There is a file named %u2018hosts%u2019. By default it is read-only. Go to it properties and uncheck the tickmark beside read-only edit it with you favourite editor. add this line at the end of it 127.0.0.1 tptools.org save it. and then restart your network interface. ( in simple words, just reconnect your interner connection ) and bingo!! the worm%u2019ll be useless. Hope this helps..

10 Tips to speed up Opera 9

                                                      Opera is already a very fast browser, but if you would have the choice between fast and faster than fast, what would you choose ? I took the liberty to compile a list of 10 great tips that speed up Opera in several unique ways. Many of the settings can be changed by simply going to Tools > Preferences in Opera but some can only be used by accessing not so obvious ways like ini files.


Please note that everything that I’m describing here worked fine on my computer. It speed up Opera and increased my browsing experience with it tremendously. While most tips will work for any users no matter their connection to the Internet some tips might only increase performance for broadband users.


Disable Name Completion and local network lookup


Whenever you enter a single word into the address field Opera will look in your bookmarks for that name and try to find a local network with the name as well. Server Name Completion tries to append prefixes and suffixes to the name automatically. While this feature might be great for some users it uses time and cpu and should be turned of for faster browsing.


Click on Tools > Preferences, select the Advanced Tab and choose Network from the left menu. Click on Server Name Completion and disable Look for local network machine and try name completion, using.
Increase the time cached images are used before checking for new versions


Opera downloads images to its cache to be able to load them faster (from your hard drive) the next time you visit the website. By default Opera checks every 5 hours if a new version of that image has appeared on the website. If you increase this time you increase your overall performance.


Go to Tools > Preferences and click on the Advanced Tab. Choose History from the left menu and select Every 24 hours or even every week for image checks. You can always refresh the cache manually by typing F5 while visiting the website.
Remove unneeded and duplicate plugins


Type opera:plugins in the address bar, this should display a list of plugins that are currently installed. Take a closer look and see if you find plugins that you never need. For instance if you never use Realplayer streams in Opera you should deactivate it.


To deactivate them open the file plugin-ignore.ini located in your Opera main directory and add the filename of the plugin that you want to disable to it.


Another problem are duplicate plugins that are caused by loading the plugins from Firefox as well. This happens of course only if Firefox is installed on the same system. You can disable this easily by typing opera:config in the address bar. Navigate to User Prefs > Plugin Path and delete the Firefox reference there.
Rebuild your profile if you have upgraded Opera (a lot)


This is only for users who upgrade Opera a lot. I for instance was using Opera since version 6 and always upgraded from the old version to a new one. This could mess up the ini files, especially the opera6.ini file which is still used in all versions of Opera. This could lead to all sorts of problems (slow page loading, high cpu usage)caused by obsolete or incorrect entries in that ini file.


The easiest approach would be to backup the file opera6.ini in your profiles folder of your Opera installation and delete it afterwards. Please note that Opera has to be closed before you do this. Restart Opera afterwards and it should automatically create a new opera6.ini file without all those old entries.


You will loose the personal information if you entered them in Opera and also all tweaks that you might have applied are gone too. It is however not a big problem to enter them again using the Preferences for the personal information and about:config for the latter.
Disable Turbo mode


While this might sound a little bit strange at first to disable turbo mode and present it as a tip to speed up Opera it becomes clear soon. Turbo mode means that Opera pre-draws any image which means that you see part of it although it is not fully loaded. This uses CPU and memory and could increase overall performance especially on slower computers. It should not be noticeable on fast computers though.


Type about:config and enter Turbo into the search field. Disable Turbo Mode and click on save.
Increase the number of total connections


If you happen to load many tabs at once and like to read websites more or less simultaneously you might want to increase the maximum number of connections. This should have a drastic impact on loading times if you use a broadband connection. It should not make a big difference for users with slow connections, such as 256K connections or less.


Type about:config and enter connections into the search field. Change the value of Max Connections Total from 20 to another value, I suggest 32 or 64 connections. The Max Connections per Server setting should remain as it is. You might even want to test a lower setting, for instance 4 connections there.
Reduce the amount of visited pages in history


Opera keeps track of the last 500 visited websites. The benefit is that Opera displays all urls that fit the string that you enter in the address bar. You can then scroll down and load the website without entering the url fully. This can however impact the time Opera needs to startup.


A temporary fix would be to clear the history manually, a better solution to reduce the amount of websites that Opera stores.


Click on Tools > Preferences and then on the advanced tab. Select History from the left menu and either click on Clear next to Addresses if you want to test if this solution really speeds up loading times or reduce the number of stored addresses in the history right away. I never use that feature and set it to 0. You might reduce it to 100 for instance.
Change Expiry Settings


Some Webmasters want you to load their website anew every time you visit it to display new ad banners for instance. This has the effect that Opera will not use the files stored in cache to load the website but request the complete website again from the server increasing load times.


We are however able to ignore the Expires meta tag from websites by changing two settings in the Opera configuration.


Write opera:config in the address bar, hit enter. Search for expiry and change the settings for Check Expiry History and Check Expiry Load to 1.
Save Images Faster


This is probably more a usablity tip than a performance tip but I think it is still nice enough to be included. Instead of saving images by right-clicking on them and selecting Save Image you can simply press CTRL and left-click the image. The download window appears and you can save it then immediately.
Delay mail and rss connections at startup


Opera prioritizes mail and rss accounts during startup. This could mean that you could witness lots of disk activity during startup which could slow down Opera significantly. It is possible to delay each account individually to prevent that Opera slows down during startup.


Locate your accounts.ini file which should be in the Opera mail folder. Every account should have an entry Initial Poll Delay=X where X should be set to at least 60 (seconds) and the rss feed to something like 120 or more.

Solar Power: The New Designs & Innovations

Solar power is no longer just about installing photovoltaic panels on existing rooftops to convert a bit of electricity with sunlight. Nowadays, people are finding unique ways to integrate solar energy into architectural, vehicular and even fashion designs from the beginning. Moreover, some innovators have even figured out ways to make structures entirely energy-independent by combining various alternative energy sources.

When solar was first introduced it was an auxiliary power source – now we have cars, boats, planes and even entire buildings that run on solar power. From the world’s first energy-autonomous vehicle to solar balloons, arcs, lily pads and even bras here are some of the most clever contemporary solar designs. These push the existing envelope of solar technology and design ingenuity.

                                                     It is hard to say whether the solar bra concept is more geared toward a male of a female audience. The stomach solar panel is perhaps a little less than sexy but supposedly generates enough energy to power a small mobile device such as an MP3 player or a cellular phone. The idea is interesting but the implementation is dubious. After all, who goes outside in only a bra? And what about the unwashability of such a clothing item...?

                                                                It has been called everything from Noah’s Eco-Arc to a giant stapler and many things in between. Born of a recall this structure was designed with reuse/recycling as well as alternative energy in mind. Following an unfortunate recall of a huge number of photovalic cells that simply could not be ethically resold Sanyo decided to use them themselves and create an amazing company structure at the same time.

                                                      One of the biggest problems, as everyone knows, with solar energy is the difficult off-times when the sun simply won’t shine (at night or during poor weather). To take advantage of even these down times systems like these that use materials (like salt) which store heat for long periods even in the absence of sun seem to be the next stage in solar energy evolution – making the absolute most out of available power and materials. What’s next on the solar horizon? Hard to say but the key elements seem to be: (a) using solar power even without the sun, (b) mixing solar power with other alternative energies and (c) making maximum use of solar power by integrating it with existing structures and vehicles at small and large scales with maximum material, time and cost efficiency.

                                                           This first commercial solar power station in Europe is a sight to behold, appearing like an alien object standing out brightly against the flat surrounding landscape. An array of solar panels around the base are used to reflect the sun direct at the giant tower in the middle where, in turn, that heat energy is used to raise the temperature of water piped through the structure. The panels are an awesome site to behold and rotate to track the sun throughout the year.
