For the last few days any time I try and do a search using google the resulting links always redirect me to a spam sight. Im using firefox3 on windows xp and have zonealarm and symantec antivirus installed. Running CCleaner seems to temporarily help the problem but it always ends up coming back sooner or later. I've done a full system virus scan and found absolutely nothing. any help/thoughts/suggestions would be great :thumbsup:

Lets take a look with Malwarebytes

Please download Malwarebytes' Anti-Malware from here:
Malwarebytes
Please rename the file BEFORE downloading to zztoy.exe instead of mbam-setup.exe

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

Double Click zztoy.exe to install the application.
* Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select "Perform Full Scan", then click Scan.
* The scan may take some time to finish,so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy&Paste the entire MBAM report (even if it does not find anything) in your next reply

Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process, if asked to restart the computer, please do so immediately.


If Malwarebytes won't install or run

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.

Ok, lets try Dr. Web:

Please download Dr. Web the free version & save it to your desktop. DO NOT perform a scan yet.

Scan with Dr. Web Cureit as follows:
• Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
• Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
• The Express scan will automatically begin.
(This is a short scan of files currently running in memory, boot sectors, and targeted folders).
• If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
• If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
• When complete, click Select All, then choose Cure > Move incurable.
(This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
• Now put a check next to Complete scan to scan all local disks and removable media.
• In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
• Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
• When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
• Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
• In the top menu, click file and choose save report list.
• Save the DrWeb.csv report to your desktop.
• Exit Dr.Web Cureit when done.
• Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
• After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

Unfortunatly I think my computer may have bit the dust.....I turned it on today to try Mr.Web and RootRepeal and was met with a BSOD. The error code was:

STOP: 0X0000007B (0xF7CAF524, 0xC0000034, 0x00000000, 0x00000000)

After some googling it looks like it might be a root sector problem. I've tried to restart the computer in various modes (safe mode, recovery mode, etc.) and keep getting the BSOD during bootup. I guess I'm looking at either reformatting or laying it permanently to rest :thumbsup:

It can be difficult to determine what exactly caused this problem. Bootup failure can be due to a variety of issues to include application faults, hardware failures, loose pin connections or malware infestation. Startup failures that occur before the OS loader (Ntldr) starts could indicate missing or deleted files, or damage to the hard disk master boot record (MBR), partition table, or boot sector. If a problem occurs during startup, the system might have incompatible software or drivers, incompatible or improperly configured hardware, or corrupted registry/system files. However, the first thing to do is check all your hardware connections and ensure they are fitted properly.

If you cannot bootup or logon in normal or safe mode, then your options are limited.If you choose Hiren's, please be aware:

While this collection of tools can be very useful, potential users should note that many of the tools are commercial applications that have not been legally licensed for redistribution, and so download/use/sharing of Hiren's BootCD may be illegal (depending on your legal jurisdiction).

http://en.wikipedia.org/wiki/Hiren%27s_BootCD

You may be able to use a Windows XP bootable Floppy Disk to boot from a diskette instead of your hard drive. If your hard drive's boot sector or Windows' basic boot files have been corrupted, this disk will circumvent the problem and boot you into Windows. If you don't have an emergency boot floppy, you may be able to use one created on another PC running Windows XP but there's no guarantee that it will boot your machine.Another option is to create a Bootable CD:These are links to Anti-virus vendors that offer free LiveCD or Rescue CD utilities that are used to boot from for repair of unbootable and damaged systems, rescue data, scan the system for virus infections. Burn it as an image to a disk to get a bootable CD. All (except Avira) are in the ISO Image file format. Avira uses an EXE that has built-in CD burning capability.If you are not sure how to burn an image, please read How to write a CD/DVD image or ISO. If you need a FREE utility to burn the ISO image, download and use ImgBurn.

Note: In order to use a rescue disk, the boot order must be set to start from the CD-ROM drive. If the CD is not first in the boot order, the computer will attempt to start normally by booting from the hard drive. The boot order is a setting found in the computer’s BIOS which runs when it is first powered on. This setting controls the order that the BIOS uses to look for a boot device from which to load the operating system. The default will normally be A:, C:, CD-ROM. Different computers have different ways to enter the BIOS. If you're not sure how to do this, refer to:If at some point, you are able to boot up but have difficulty running programs, you can try using the VIPRE Rescue Program - the size of the downloaded application is large. This is a utility designed to scan and clean a computer which is so badly infected that most programs cannot run. Virus definitions are included and the program is self-running once executed. All scans include Rootkit Detection. Be sure to print out and follow the instructions provided on the same page for running under Windows or with the Command Line option from Safe Mode with Command Prompt.
