    I recently scanned my computer with AVG, to find an infection called Trojan Horse ZBot.fxs. Now AVG reports that it successfully removed the threat, but my computer's still acting quite dodgy. Programs freezing up and general sluggishness. Also found a few PUP's suddenly appearing on my computer (Like I scanned with MBAM yesterday, clear. Scanned today and I find some PUP installer thing). I'm not sure if there's something else going on here.

    Hello and welcome to Computer Hope Forum. My name is Dave. I will be helping you out with your particular problem on your computer.

    1. I will be working on your Malware issues. This may or may not solve other issues you have with your machine.
    2. The fixes are specific to your problem and should only be used for this issue on this machine.
    3. If you don't know or understand something, please don't hesitate to ask.
    4. Please DO NOT run any other tools or scans while I am helping you.
    5. It is important that you reply to this thread. Do not start a new topic.
    6. Your security programs may give warnings for some of the tools I will ask you to use. Be assured, any links I give are safe.
    7. Absence of symptoms does not mean that everything is clear.

    If you can't access the internet with your infected computer you will have to download and transfer any programs to the computer you're using now and transfer them to the infected computer with a CD-RW or a USB storage device. I prefer a CD because a storage device can get infected. If you use a storage device hold the shift key down while inserting the USB storage device for about 10 secs. You will also have to transfer the logs you receive back to the good computer using the same method until we can get the computer back on-line.
    *************************************************************************
    Remove the Adware:
    • 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.
    *********************************************
    Update Your Java (JRE)

    Old versions of Java have vulnerabilities that malware can use to infect your system.


    First Verify your Java Version

    If there are any other version(s) installed then update now.

    Get the new version (if needed)

    If your version is out of date install the newest version of the Sun Java Runtime Environment.

    Note: UNCHECK any pre-checked toolbar and/or software offered with the Java update. The pre-checked toolbars/software are not part of the Java update.

    Be sure to close ALL open web browsers before starting the installation.

    Remove any old versions

    1. Download JavaRa and unzip the file to your Desktop.
    2. Open JavaRA.exe and choose Remove Older Versions
    3. Once complete exit JavaRA.

    Additional Note: The Java Quick Starter (JQS.exe) adds a service to improve the initial startup time of Java applets and applications. To disable the JQS service if you don't want to use it, go to Start > Control Panel > Java > Advanced > Miscellaneous and uncheck the box for Java Quick Starter. Click OK and reboot your computer.
    *************************************************
    Please download Junkware Removal Tool to your desktop.

    Warning! Once the scan is complete JRT will shut down your browser with NO warning.

    Shut down your protection software now to avoid potential conflicts.

    •Temporarily disable your Antivirus and any Antispyware real time protection before performing a scan. Click this link to see a list of security programs that should be disabled and how to disable them.

    •Run the tool by double-clicking it. If you are using Windows Vista or Windows 7, right-click JRT and select Run as Administrator

    •The tool will open and start scanning your system.

    •Please be patient as this can take a while to complete depending on your system's specifications.

    •On completion, a log (JRT.txt) is saved to your desktop and will automatically open.

    •Copy and Paste the JRT.txt log into your next message.
    *******************************************
    Malwarebytes' Anti-Rootkit

    Please download Malwarebytes' Anti-Rootkit and save it to your desktop.
    • Be sure to print out and follow the instructions provided on that same page for performing a scan.
    • Caution: This is a beta version so also read the disclaimer and back up all your data before using.
    • When the scan completes, click on the Cleanup button to remove any threats found and reboot the computer if prompted to do so.
    • Perform another scan with Malwarebytes Anti-Rootkit to verify that no threats remain. If they do, then click Cleanup once more and repeat the process.
    • If there are problems with Internet access, Windows Update, Windows Firewall or other system issues, run the fixdamage tool located in the folder Malwarebytes Anti-Rootkit was run from and reboot your computer.
    • Two files (mbar-log-YYYY-MM-DD, system-log.txt) will be created and saved within that same folder.
    • Copy and paste the contents of these two log files in your next reply.
