Hi Joe,

Download, install, update and run the FREE version of Malwarebytes.

Post the log file here once the scan is completed.

Forget AVG, their reputation is not what it once was - uninstall it completely and replace it with Microsoft Security Essentials, once this other bit of malware has been removed.

Regards,
Golden

Joe,

If you are having problems running Malwarebytes when you boot your PC normally, then reboot it in SAFE MODE (hit F8 continuously during reboot) and then run Malwarebytes.

Post back here if you are having problems with that or you need more help.

Regards,
Golden

Symantec has a free removal tool for Blaster:

In many cases, you will need to do this before continuing with the removal instructions.

hi GOLDEN Thankyou Once Again !!!
what I did --
Ran my System in Safe mode with networking..it gave the results and i clicked on "remove all the infections"..it then asked for a reboot and i did it..
( Downloaded Malwarebytes from my frds laptop, saved to a flash drive and then put my system in safe mod and ran the malware frm the flash drive)

Now the annoying pop windows dont appear !! i am now able to open all the files and folders !!! So happy !!!!

The only problem now is when i m tryi to connect to the internet with my friends wifi connection Firefox(version 5.0) it says " The Proxy server is Refusing Connections. Firefox is configured to use a proxy server that is refusing connections..
Internet explorer also tells " Internet Explorer cannot display the webpage..

Hi,

Please copy & paste this information into a batch file and save as flush.bat on your desktop:

@Echo on
pushd\windows\system32\drivers\etc
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
popd
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
del %0


Right-click on flush.bat and choose run as administrator. Try to connect to the internet after you have done this.

You should keep Malwarebytes on your system, and update and scan with that regularly.

Regards,
Golden

I agree with Golden on his post, those commands in a batch file should fix you up if it has been corrupted.
