    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 Trojan was 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. Download, and install WOT (Web OF Trust): http://www.mywot.com/. It'll warn you (in most cases) about dangerous web sites.

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

    7. Run Temporary File Cleaner (TFC) weekly.

    8. 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.

    9. (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.

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

    11. 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.

    12. Read How did I get infected?, With steps so it does not happen again!: http://www.bleepingcomputer.com/forums/topic2520.html

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

    A security box is on my screen and I don't know what to do with it. It says;
    WINDOWS SECURITY ALERT
    Windows firewall has blocked some features of Norton Online Backup Service
    on all public and private access.

    This program has already been blocked or unblocked for a different network location.
    Allow Norton Online Backup Service to communicate on these networks:
    x Private network
    Public network
    Allow Access Cancel

    I did not know if I should Allow or cancel so I left the box on my desktop.

    I just noticed that when I wrote down everything to do I completely missed step 2 in the OTL.exe. (the clean-up) Will that harm my system that I forgot that part?

    That would be safe to allow.

    You can do it now.

    Any current issues?

    My computer is running a lot quicker just going from page to page. I haven't noticed any glitches on my desktop and my files that were unsearchable have been found.
    Thank you for all the time you put into helping me with my computer.
    I have followed the rest of your suggestions and I am going to go over with my teenager safer internet protocols and set him up with a separate user account.

    Thanks again and have a great weekend
