    Try to run the scan from safe mode.

    I gave you the wrong error message before. What it actually said when I originally tried to run the program in "Normal" mode was "ContentWatch has detected that one or more critical files is missing or has become corrupt. Please try to uninstall and reinstall."

    I was able to download the program again this morning and ran it it safe mode. While it was running, I received several of the older "there is a problem with your ContentWatch installation" error messages. These did not appear to prevent the program from running.

    The program completed 99% of it's scan with no threats detected, but then it became hung up. It sat on 99% for over 30 minutes with no further objects being scanned. For whatever it's worth, the object it was on when it became hung up was C:\_OTL\Movedfiles\04162...\_uninst_.lnk

    I had to restart the computer into normal mode to be able to post this message. When I restarted in Normal mode, I received about 8-10 of the previously mentioned error messages "ContentWatch has detected that one or more critical files is missing or has become corrupt. Please try to uninstall and reinstall."

    That error comes from Net Nanny Parental Controls.
    Uninstall it.

    Did Kaspersky find anything?

    It did not find anything with 99% being scanned, but as I said, it did not completely finish. I don't know if the ContentWatch errors had any effect on it.

    Do you want me to Uninstall the Net Nanny and try to run the program again?

    Uninstalled the Net Nanny and ran again. It seemed to run better this time with no error messages popping up.

    It DID find and delete 1 threat which it said was a trojan of some kind. However, when I went to try and copy the log at the end, the machine hung up and stopped responding. I was unable to copy the log, sorry.

    I've clicked around a bit. The redirect has not reoccurred...yet. :)

    I'll report if it does.

    Otherwise, seems to be running pretty well.

    Still going strong.

    I want to thank you so much for your efforts here. I know it's taken longer than usual. I'll definitly be donating to the cause.

    I had a question about clean-up steps, which I've seen you post in some other threads. Anything special I need to do, or could I copy those steps from out of those other threads?

    Right, sorry about it.

    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.
