    1. Update your Java version here: http://www.java.com/en/download/installed.jsp

    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 and 7 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:

    Code:
    :OTL
    :Commands
    [purity]
    [emptytemp]
    [EMPTYFLASH]
    [emptyjava]
    [CLEARALLRESTOREPOINTS]
    [Reboot]
    • 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 - https://www.mozilla.org/en-US/plugincheck/
    other browsers: https://browsercheck.qualys.com/ (click on "Launch a quick scan now" link)

    6. Download, and install WOT (Web OF Trust): http://www.mywot.com/. 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): http://secunia.com/vulnerability_scanning/personal/. 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 FileHippo.com 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:

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

    Thanks for all the help so far, but I have potentially bad news...

    I was working on step 5, and went to look for an update to Adobe Acrobat Pro, and started getting browser redirects in Firefox. It doesn't appear to be happening in IE though.

    Firefox reinstalled.

    Should I re-run some scans? After this re-happened I am nervous to start popping in my password and checking my email again.

    Thanks for all the help.

    You definitely have to change sensitive passwords because trojans were present.
    You can do this from this computer since it's clean.
    Is Firefox OK now?
    Any other issues?

    Everything appears to be ok. I'll keep an eye on it over the next few days.
    I changed a bunch of passwords the other day from my wife's clean computer, and haven't used this computer until I knew it was good to go.

    What, in you opinion, is the best program to use to rescan my external hard drive when I plug it back it to make sure my backed up files are clean too?

    Thanks a ton for your help. I just shot you some love on PayPal.

    Thank you :)

    Install Panda USB Vaccine, or BitDefenderā€™s USB Immunizer on your computer to protect it from any infected USB device.
    Then plug any external device in and scan it with your updated AV program.

    Good luck and stay safe :)
