AVG detecting viruses on a daily basis - Help

By lolguy04
Feb 7, 2009
  1. Hi, I am in desperate need of help. I set my antivirus (AVG) to run scans daily. Everyday it finds at least one infection. I am finding more and more of this "Win32Cryptor", among others.
    I have a log of the most recent scan showing 23 infections. I am afraid for my computer and need some help. Can anyone run me through what I am supposed to do to fix these problems. Please and thanks. :)

    R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Default_Page_URL =
    R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Default_Search_URL =
    R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar =
    R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page =

    You did not remove the item found by MBAM you need to run MBAM again and Netx to select and remove.

    So update MBAM and run quick scan and remove.

    Same with SAS Check to select the tracking cookies and remove them.

    Then do the below...

    Download SDFix to Desktop.

    On Desktop run SDdFix It will run (install) then close.

    Then reboot into Safe Mode

    As the computer starts up, tap the F8 key several times.

    On the Boot menu Choose Safe Mode.

    Click thu all the prompts to get to desktop.

    At Desktop
    My Computer C: drive. Double-click to open.

    Look for a folder called SD Fix. Double-click to enter SD Fix.

    Double-click to RunThis.bat. Type Y to begin.

    SD Fix does its job.

    When prompted hit the enter key to restart the computer

    Your computer will reboot.

    On normal restart the Fixtool will run again and complete the removal process then say Finished,
    Hit the Enter key to end the script and load your desktop icons.

    Once the desktop is up, the SDFix report will open on screen and also be saved to the SDFix folder as Report.txt.
    Attach the Report.txt file to your next post.
    Download ComboFix

    NOTE: If you have had ComboFix more than a few days old delete and re-download.

    Get it here:
    Or here:

    Double click combofix.exe follow the prompts.

    When finished, it will open a log.
    Attach the log and a new HJT log in your next reply.

    Note: Do not click combofix's window while its running. That may cause it to stall.

    Back again, here are all the logs. Sorry it takes me so long. Im trying to do this with dialup internet lol.
    Another thing, I updated Mbam and ran two scans, first a quick scan like you said, then a full one because the first had no infections, but the full had no infections either. Both times Mbam couldnt find the malware that i didnt remove in the previous scan.
    What does this mean?...nothing bad I hope.

    Good morning

    Looks good.

    Run ComboFix once more to confirm it finds no more and has clean log!

    Also a status report of how computer is running now and any remaining issues.

    One more swipe!

    Cut for pasting pull to bottom watch the side slider, the above text inside the box.Then open new Notepad document on Desktop then paste and save as CFscript.txt to the Desktop

    EXIT ALL BROWSERS before continuing!
    You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
    Now use your mouse to drag CFscript.txt on top of ComboFix.exe

    Follow the prompts.
    When it finishes, a log will be produced named c:\combofix.txt. Attach that back here.

    Yes you are!

    Great job!

    Some closing comments and actions!

    Thread closing-------------------------------------------------------------------

    Some of these tools update so often they require downloading again later if needed. But keep and run MBAM and SAS to maintain.

    Remove ComboFix
    combofix /u
    Hit enter or click OK.

    Please download OTCleanIt

    Save to desktop.

    This will remove all the tools we used to clean your computer.

    Double-click OTCleanIt.exe. Click CleanUp. Yes to the "Begin cleanup Process?"

    Approve all if prompted by Firewall. Approve Widows Defender or other guards or security programs while OTCleanIt attempting access to the Internet to allow all.

    If prompted to Reboot click, Yes.
    OTCleanit will delete itself when finished, If not delete it by yourself.

    Run CCleaner again twice or more on Cleanup temps, then on left click Registry then Scan for issues also repeat till clean.

    Run ATF-Cleaner Temp and Registry, repeatedly until no more found.

    Fantastic cleaner.
    The issues can and are likely found is in System Restore so do the below

    Start-Programs-Accessories-System Tools-Disk- System Restore and create a new Restore point. Name it "After cleanup at TechSpot".

    Then Start-Programs-Accessories-System Tools-Disk Cleanup
    Click OK to accept C:
    Select all Boxes
    Then click More Options
    Here click System Restore and OK to "Are you sure" and the OK to Run.

    As this runs it clears all but the most recent Restore Point but it does one other thing that can contain infested files and a huge amount of disk space.

    It clears what is known as Shadow copies which are used by specialized back up programs.

    This is if you have the Volume Shadow Copy running which is the default.

    Every two weeks or so, run MBAM and SAS until clean.

    They take a while, so leave scanning while you are sleeping working or watching TV. If not done under the gun they can be scheduled not to interfere with computer time.

    If they find something they can not clean, then get back to us.

    Additionally run CCleaner. ATF-Cleaner and KCleaner.
    I have been using ThreatFire for more than a year, it just went from ver 3 to ver 4.

    It was designed to be used with and to co-exist with other Virus scanners.

    Additionally it uses a totally different process to protect. While conventional Virus scanners work from definitions ThreatFire works on recognizing Virus/Malware activity.

    It's like looking at it with 2 sets of eyes and from a different angle.

    It works like some Firewalls do to learn what is good/bad.

    After install it will ask you about everything that could be a security issue. For example the first time you run IE or FireFox it will prompt you. You would answer to approve and remember the setting. From then on no more prompts about IE or FireFox unless the exe changes like in an update.

    As it queries you about the prompt to help you determine to approve or not you can google it with one click.
    Look at

    Run SpyBot ocassionally and use the Immunize function.

    I highly reccomend Hostman: Hostman

    Download install run and allow it to disable DNS Client and select all Host files and then Update and install all host files.

    A Disk Scan (chkdsk) and Defrag are in order.
