    I cannot load SANS , Microsoft, AVG etc ... websites associated with security, I cannot loadup updates for virus checking because of this.

    I have another partition with Windows 7, I can load all websites on this partition.

    I loaded AVG on Windows 7 Partition, and ran it on the primary partition (Windows XP), it caught some malware. Also used Malwarebytes on it.

    The problem still persists ....

    Have checked HOST file, and nothing out of the ordinary ...

    Try pinging the ip address of microsoft, sans etc. Maybe something has hooked a function required to make a dns request?
    Also try surfing the sites using the ip address.
    Post up your "netstat -f" output while your trying to surf those particular sites.

    If none of the above works try "net stop dnscache" and try the above again.

    just thought of another thing too.

    have a look at the output from this command "ipconfig /displaydns"

    Read this

    http://www.secureworks.com/research/threats/downadup-removal/


    Use the F-Secure alternative link, and run the tool with

    --disinfect

    You have Conficker on your laptop


  • Registered Users Posts: 367 ✭✭900913


    I downloaded ftp://193.110.109.53/anti-virus/tools/beta/f-downadup.zip
    But 5 mins into the scan I got blue screen of death (BSOD).
    So now Im using my duel boot ubuntu. I should be able to scan my win7 partition from within ubuntu, maybe using Wine.

    I will search google for a linux app that will find and clean Conficker.

    Thanks for the info CFC1969

    Use f-prot linux edition

    It can scan the mounted win7 partition if you use ntfs-3g to read write to drive.

    I boot off a cd and do the above any time a relation infects there pc and it works very well.
