  1. I am infected by the vundo trojan and can not seem to get rid of this thing. It all started when my wife decided to join myspace and click on links that would allow her to tweak her myspace profile. Nex thing I know, we are getting pop ups like crazie, and .dll startup error messages and Norton antivirus realtime alerts that vundo exists but Norton's cant do anything about it. Attached is my HJTlogfile. Please let me know what to do next. I would greately appreciate the assistance.

    Anti Root kit reported no problems. AVG anti spyware is bundled into AVG security. The link that you gave me only allows for anti-virus to be installed, not anti-spyware. Attached are the HJT logs and combofix log.

    Time to update the instructions. AVG just started doing that. Also did you use to have Norton then removed it?

    You aren't running Firewall Software. Please download and install one of these first!

    Use a Firewall - It is very important that you use a Firewall on your computer. If you use the Windows Firewall you might think that's enough but it only controls inbound traffic. Simply using a Firewall in its default configuration can lower your risk greatly. Here are some firewalls which are free for personal use and most commonly used:

    I have never had a software firewall before and have never ever once gotten a virus or any sort of adaware problem until now. I do have a Linksys router that I use as my firewall and have it locked down pretty good.

    Attached are the logs you requested.

    I see entries for Mcafee, Norton, and AVG all active in memory.

    I am guessing you want to keep AVG?

    Run this... Norton Removal Tool =

    Go to Start - control panel - add/remove programs - uninstall Mcafee


    Do a scan with Hijackthis and check the following entries

    O2 - BHO: (no name) - {05BE0ECB-15CB-4505-AD94-D4706DD9C431} - C:\WINDOWS\system32\iifdccYS.dll (file missing)
    O2 - BHO: (no name) - {4789D447-1462-4A3D-8917-1E41F140EB67} - C:\WINDOWS\system32\xxyawtsQ.dll (file missing)

    Close all windows except Hijackthis and select Fix Checked

    Close Hijackthis for now


    Run Kaspersky Online AV Scanner

    Order to use it you have to use Internet Explorer.
    Go to Kaspersky and click the Accept button at the end of the page.

    Note for Internet Explorer 7 users: If at any time you have trouble with the accept button of the licence, click on the Zoom tool located at the right bottom of the IE window and set the zoom to 75 %. Once the license accepted, reset to 100%.
    • Read the Requirements and limitations before you click Accept.
    • Allow the ActiveX download if necessary.
    • Once the database has downloaded, click Next.
    • Click Scan Settings and change the "Scan using the following antivirus database" from standard to extended and then click OK.
    • Click on "My Computer"
    • When the scan has completed, click Save Report As...
    • Enter a name for the file in the Filename: text box and then click the down arrow to the right of Save as type: and select text file (*.txt)
    • Click Save - by default the file will be saved to your Desktop, but you can change this if you wish.
    Attach the report into your next reply

    There is nothing in add/remove programs for MaCafee. The "remove" Norton link you sent, does that remove Norton anti-virus from my PC? If so, I dont want to do this as this is my main AV software.

    The txt file for the scan is too large. It is 127kb.

    Like I said I was guessing you wanted to keep AVG. You need to uninstall AVG as having 2 active AV programs is not good.

    Attach it as 2 separate files

    AVG has been removed.

    Here are the two attachments.

    I looked through Symantec knowledge base and it looked like your product is discontinued. Not 100% on that though.

    Most of the kaspersky log is just a Quarantined infection in the Norton

    1) Navigate to and delete the contents of this folder but not the folder itself:
    C:\Documents and Settings\All Users\Application Data\Symantec\Norton AntiVirus Corporate Edition\7.5\Quarantine

    2) VERY IMPORTANT - Did you knowingly install the TWD Industries remote administration tool, also known as VNC Viewer? The reason I ask is because it could be considered legit if you used it for help ect. But if an infection installed it on your behalf somebody may have had full access to everything on your machine.

    Yes I purposely installed VNC on this machine.

    I also followed the steps to delete the qurantine items.
