Chrome blocking extensions

[SpringWater]

On one of my laptops there is this extension installed called default extension and it makes it so when I click on any link instead of taking me to the website it's supposed to take me to, it opens up some other random website. I removed the extension but it keeps coming back (probably caused by a virus), so my question is, is there any way I can block this extension from installing itself? (I tried scanning the computer with anti-viral software but it doesn't detect anything)

Run tdsskiller first.

Please download and run TDSSkiller

When the program opens, click on the start scan button.

TDSSKiller will now scan your computer for the TDSS infection. When the scan has finished it will display a result screen stating whether or not the infection was found on your computer. If it was found it will display a screen similar to the one below.

To remove the infections simply click on the Continue button and TDSSKiller will attempt to clean them or remove them.

After trying to clean them it will pop up with the results of the scan and its actions.

Please reboot the system if asked to do so.

After running there will be a log that will be located at the root of your c:\ drive labeled tdsskiller with a series of numbers after it example, C:\TDSSKiller.2.4.7_23.07.2010_15.31.43_log.txt

Please open the log and copy and paste it back here.

then do the following.

Please download AdwCleaner by Xplode onto your Desktop.



•Please close all open programs and internet browsers.
•Double click on adwcleaner.exe to run the tool.
•Click on Delete.
•Confirm each time with OK
•Your computer will be rebooted automatically. A text file will open after the restart.
•Please post the content of that logfile in your reply.
•You can find the logfile at C:\AdwCleaner[Sn].txt as well - n is the order number.
