I have been having multiple problems with my computer of late.

I'm using Windows XP, with firefox, and AVG 8 free edition. AVG keeps showing threat detected in my C:\WINDOWS\Temp folder. A random named folder (always a .tmp folder) keeps getting created with an svhost.exe file found there. I cannot heal this, only remove this to the vault.

The threat name is Trojan horse PSW.Generic7.BEMV.

Process name: C:\WINDOWS\system32\svhost.exe
Process ID: 1280

I also have random new tabs being created when on firefox that go to different sites, some after clicking on a search in google, others while I'm surfing another site.

At the moment I'm running a System scan with AVG and its still going but has already found this;

Trojan horse BackDoor.Agent.AFIY
C:Documents and Settings\Administrator\Local Settings\Temp\Jxb.exe

I've downloaded HJT to my computer and left a shortcut to the desktop, but have not attempted anything else yet. What steps should i take now?

Just noticed something weird, dont know if this helps.

All of my RSS feeds to different news agencies only show articles from Wednesday 20th January, 6 days ago. There have been no updates since that time.

Hello and welcome please run these next. If you have Spybot installed temporarily disable it.
Next run ATF:
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

Please download ATF Cleaner by Atribune & save it to your desktop.
  • Double-click ATF-Cleaner.exe to run the program.
  • Under Main "Select Files to Delete" choose: Select All.
  • Click the Empty Selected button.
  • If you use Firefox browser click Firefox at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • If you use Opera browser click Opera at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • Click Exit on the Main menu to close the program.

Next run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

Please download Malwarebytes Anti-Malware and save it to your desktop.

alternate download link

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.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Thanks for responding 'Boopme'

Lastnight after reading through this forum and getting some minor insight into what was going on i decided to download and try 'MBAM'. This seemed the most like my own AVG software and less complicated than things like HJT and other software mentioned here without your sites proffesional instruction. It found around 9 Trojans and the like and I think deleted them, and needed a reboot to remove those difficult ones. I followed the instructions and rebooted. I noticed once maybe twice throughout the course of the rest of the night that I had the same AVG threat alerts regarding the same problem, but no (as far as I can remember) redirects or new tabs being created in firefox. I honestly dont think the problem is fully solved but (at the least) its made a dent in the problem.

Tonight I will follow your instructions to the letter, unless you think my actions have maybe changed the approach since i last posted? At the moment I'm on a different computer elsewhere and cannot post the log file, but will definitely do so later on. I was wondering though what the purpose was of the following;

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.


as i never knew I had to do this, and cannot understand why this would have to occur, could you please explain this further.

Hello, that was good. We will still need to see the log. It tells me the types of infection and what needs to be done to cure it.
Also please reun MBAM ,this time select FULL scan.

Rerun MBAM (MalwareBytes) like this:

Open MBAM in normal mode and click Update tab, select Check for Updates,when done
click Scanner tab,select FULL scan and scan (normal mode).
After scan click Remove Selected, Post new scan log and Reboot into normal mode.

Some types of malware will disable MBAM (MalwareBytes) and other security tools. After multiple issues of rplies wit "MBAM will not install,"I then had to reply with "try renaming it." So to save time between 2 replies . I just added that step with a random name (zztoy.exe) to my instructions.

We should still run these next regardless.



Next run ATF and SAS: If you cannot access Safe Mode,run in normal ,but let me know.

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware , Free Home Version. Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining
.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program
.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.


Please ask any needed questions,post logs and Let us know how the PC is running now.

Still getting these threat messages:

This is the same threat detectin I'm getting, time and time again the same thing, the only thing that changes is the name of the .tmp folder, its always a 4 letter word made up of 4 random letters. This is what my Temp directory looks like now:

Posted Image

Absolutely full of randomly named .tmp files.

I followed your advice this afternoon and booted to safe mode and carried out the ATF-Cleaner and SAS scan. Heres the SAS scan log:

The system seems to be running as usual, with no redirects but still with the constant Threat detections in my C:\WINDOWS\Temp folder

Bear in mind that I never carried out any MB scans in SafeMode, should I?

So What Next?......................................

BTW thanks for everything so far.

MBAM is designed to be at full power when running in normal mode and loses some effectiveness for detection & removal when used in safe mode. Therefore, if you installed it in Safe Modeafter completing a scan it is recommended to uninstall MBAM, then reinstall it in normal mode and perform another Quick Scan.


Now this appears to be a Script malware and as such needs to be carefully removed to prevent an unbootable PC.
Do the HJT instructions below. Include those 2 images.

You will need to run HJT/DDS.
Please follow this guide. go and do steps 6 thru 8 ,, Preparation Guide For Use Before Using Hijackthis. Then go here HijackThis Logs and Virus/Trojan/Spyware/Malware Removal ,click New Topic,give it a relevant Title and post that complete log.

Let me know if it went OK.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/291368/keep-getting-this-threat-detected-trojan-horse-pswgeneric7bemv-and-new-tabs-to-random-sites-appear/ you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days, up to two weeks perhaps less, to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :thumbsup:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
