    After running TFC I got a windows message stating that windows had encountered a critical error and needed to reboot. The computer rebooted by itself shortly after. Running ESET next, will post when I'm done. I'm also getting a notice for Java to update. Should I go ahead and update it?

    ESET online scanner is stopped at 4% of initialization and gives the message "Can not get update. Is proxy configured?"
    What should I do?

    Stop the scan and use different browser.

    I've tried it with Chrome, Internet Explorer and Firefox. Same problem with each one.

    1. Update your Java version here:

    Note 1: 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.

    Note 2: The Java Quick Starter (JQS.exe) adds a service to improve the initial startup time of Java applets and applications. If you don't want to run another extra service, go to Start > Control Panel > Java > Advanced > Miscellaneous and uncheck the box for Java Quick Starter. Click OK and restart your computer.

    2. Now, we need to remove old Java version and its remnants...

    Download JavaRa to your desktop and unzip it.
    • Run JavaRa.exe (Vista users! Right click on JavaRa.exe, click Run As Administrator), pick the language of your choice and click Select. Then click Remove Older Versions.
    • Accept any prompts.
    • Do NOT post JavaRa log.


    Your computer is clean [​IMG]

    1. We need to reset system restore to prevent your computer from being accidentally reinfected by using some old restore point(s). We'll create fresh, clean restore point, using following OTL script:

    Run OTL

    • Under the Custom Scans/Fixes box at the bottom, paste in the following:

    • Then click the Run Fix button at the top
    • Let the program run unhindered, reboot the PC when it is done
    • Post resulting log.

    2. Now, we'll remove all tools, we used during our cleaning process

    Clean up with OTL:

    • Double-click OTL.exe to start the program.
    • Close all other programs apart from OTL as this step will require a reboot
    • On the OTL main screen, press the CLEANUP button
    • Say Yes to the prompt and then allow the program to reboot your computer.

    If you still have any tools or logs leftover on your computer you can go ahead and delete those off of your computer now.

    3. Make sure, Windows Updates are current.

    4. If any trojans, rootkits or bootkits were listed among your infection(s), make sure, you change all of your on-line important passwords (bank account(s), secured web sites, etc.) immediately!

    5. Check if your browser plugins are up to date.
    Firefox -
    other browsers: (click on "Launch a quick scan now" link)

    6. Download, and install WOT (Web OF Trust): It'll warn you (in most cases) about dangerous web sites.

    7. Run Malwarebytes "Quick scan" once in a while to assure safety of your computer.

    8. Run Temporary File Cleaner (TFC) weekly.

    9. Download and install Secunia Personal Software Inspector (PSI): The Secunia PSI is a FREE security tool designed to detect vulnerable and out-dated programs and plug-ins which expose your PC to attacks. Run it weekly.

    10. (optional) If you want to keep all your programs up to date, download and install FileHippo Update Checker.
    The Update Checker will scan your computer for installed software, check the versions and then send this information to to see if there are any newer releases.

    11. (Windows XP only) Run defrag at your convenience.

    12. When installing\updating ANY program, make sure you always select "Custom " installation, so you can UN-check any possible "drive-by-install" (foistware), like toolbars etc., which may try to install along with the legitimate program. Do NOT click "Next" button without looking at any given page.

    13. Read:
    How did I get infected?, With steps so it does not happen again!:
    Simple and easy ways to keep your computer safe and secure on the Internet:

    14. Please, let me know, how your computer is doing.

    Regarding JavaRa...
    When I ran it, it said it was finished searching for old versions and was creating a log file. But then when it went to display the log file it said it could not find it. Since the log file wasn't created/doesn't exist... did this do what it was supposed to?

    I still had old Java stuff so I uninstalled it as it said to do on the Java site. Everything seems to be running great, thanks soooooo much! You have no idea how much I appreciate it!

    Can I delete from the desktop: MBR.dat, Security Check, and JavaRa?
  14. Broni

    Broni Malware Annihilator Posts: 54,260   +383

    Yes, you can delete those.

    Way to go!! [​IMG]
    Good luck and stay safe :)
