  1. hello,

    Can someone please help!!!

    my avg detected js downloader.agent and I followed all the steps to remove it.

    also, I ran avg again and it says that there is another problem:

    Object: C:\\windows\system32\drivers\etc\hosts
    Result: change

    is this another virus?

    Thank you,

    Sorry to be a pain

    I use computer for my finances and really would hate any of my personal information to be stolen. Can someone let me know if the virus has been deleted.

    Thank you in advance,

    Update your Java Runtime Environment
    • First try going to Start -> Control Panel -> double click Java
    • Select the Update TAb at the top
    • Click the Check for Updates button at the bottom
    • If it finds the newer version (Java 6 Update 5) Follow the on screen instructions
    • After it installs the newest version Go back to Control Panel -> Add/remove programs
    • Uninstall any older versions of Java

    If for some reason you couldn't update through the above instructions.
    • Click the following link
      Java Runtime Environment 6 Update 5
    • The 4th option down is the one you want (click Download)
    • Check the box to agree to terms of service
    • Check the box for your operating system and click 'Download selected'at the bottom
    • After the install Go to Start-> Control Panel-> add/remove programs (Programs and features), and uninstall any old versions
    • Navigate to C:\programfiles\Java -> delete any subfolders except the jre1.6.0_05 folder

    The rest of your log looks clean, ill maybe see if someone else wants to have a look over it though.

    After doing this,
    Boot into safe mode,
    Show hidden files and folders,
    and do a scan with AVG antivirus
    and AVG antispyware, remember to set it to quarantine the results and post back the logs.

    Boot back into normal mode and rehide your hidden files,

    Run HJT and post back that log as well.

    Thank You

    You do not understand how much this means to me. I have not had a virus in many years, and usually very careful about the sites that I visit. I will follow your instructions and post back. Meanwhile, can someone else please confirm that my computer "is o.k."

    Like I mentioned before I use this computer for my personal finances so it would be detrimental for it to be hijacked.

    thanks again

    Lets see what the logs say.

    Do you have a Canon MP830? And also nVidia graphics card?

    I just need to check some of the entries that they arent malicious.

    Updating your Java is very important, you have jre1.5.0, whereas we are on jre1.6.0_05. Your version had some problems with it.

    Did you run AVG anti-spyware? I noticed you posted a deckard scan, combofix, and hijackthis. If you did can you attach the log here as well.

    If not follow below...

    AVG Anti Spyware
    • Download and install the latest version of AVG Anti Spyware
    • Click Save File on the box that pops up after clicking the link
    • The AVG installer will download to your desktop, Double click on this Icon
    • In the installer Click Next, I agree, Next, Install, after it extracts the files, check box to launch AVGAS then Finish
    • With the program launched, Select the Icon at the top that says UPDATE then Start Update in the left pane
    • Now select the Icon at the top that says SHIELD then at the top of the left pane change "Resident Shield is ..." from Active to Inactive
    • After the update click on the Scanner Icon at the top, then select the settings tab, in the first section "How to act?" click on recommended actions and change it to delete.In the reports section make sure it is set to Automatically generate report after every scan
    • Click back to the Scan tab and select Complete System Scan

    Here is the hijack file. I could not get the file from the avg spyware file because I did not have a log file to save. I do not know what is wrong.

    Also the host file is to large to upload.

    Thank You

    Your log looks better, will you try and upload another AVG antispyware log?

    How are the problems you were experiencing now?

    NOD32 is good but AVG and Avast! are just as good and they come at a much better price, ie free.

    You dont always get a better result just by paying for it, look at Norton, its unbelievably rubbish.
