    As can be seen, the last scan found some trojans. Not sure whether my computer can be considered clean with that. I saw that Java, Adobe Reader and Flash Player were out-dated. I re-installed updated versions.

    Do you think it is already save to access my mails etc. on this computer or do you recommend to wait until the end of the cleaning process?
    Let me know. So far, thanks a lot !!!

    [​IMG] Eset found items already quarantined by FRST. Nothing to worry about.

    [​IMG] Update Adobe Flash Player: http://get.adobe.com/flashplayer/
    Make sure you UN-check Yes, install McAfee Security Scan Plus

    NOTE 1: Beginning with Adobe Flash Version 11.3, the universal installer includes the 32-bit and 64-bit versions of the Flash Player.
    NOTE 2: While installing make sure you UN-check any extra garbage which wants to install alongside.

    [​IMG] Update Adobe Reader

    You can download it from http://www.adobe.com/products/acrobat/readstep2.html
    After installing the latest Adobe Reader, uninstall all previous versions (if present).
    Note. If you already have Adobe Photoshop® Album Starter Edition installed or do not wish to have it installed UNcheck the box which says Also Download Adobe Photoshop® Album Starter Edition.

    Alternatively, you can uninstall Adobe Reader (33.5 MB), download and install Foxit PDF Reader(3.5MB) from HERE.
    It's a much smaller file to download and uses a lot less resources than Adobe Reader.
    Note: When installing FoxitReader, make sure to UN-check any pre-checked toolbar, or any other garbage.

    [​IMG] 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.

    ===================================

    [​IMG] 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:

    Simple and easy ways to keep your computer safe and secure on the Internet: http://www.bleepingcomputer.com/tutorials/keep-your-computer-safe-online/

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

    Hi Broni, I am executing the final steps you wrote.

    My computer is doing very fine and I am have the impression that it is cleaner than ever before (maybe due to the effort we put into it).

    I would like to thank you A LOT for your efforts! It is remarkable how consistently you guys find time to help us out on a voluntary base; in addition, you seem to have a vast knowledge about current security issues and tools available. Thumbs up!

    I have a final question: is there a tool you would recommend with which I can choose the services automatically started at windows start up?
    I found AVG PC TuneUp very practical, but they only offer a 1-day trial version. So I am looking for a free light-weight application.

    Thanks!

    Services are best to be left alone.
    This is not like 20 years ago when we're scrambling for every bit of computer power.
    Today's computers have great processors, lot of RAM so number of services is not an issue at all.

    Good luck and stay safe :)
