Hello. It's a Windows XP and I was using Firefox web browser and I have McAfee Security suite installed.
I was surfing the internet, I followed a link from Google (McAfee Site adviser said it was a green site.) A Pop up came up, I closed it another window opened my computer beeped some windows flashed on screen quickly. I quickly closed Firefox but then McAfee then shut itself down, when I started it up again lots of programs were requesting internet access and some trojans were automatically blocked. I blocked all the programs that requested access but I'm sure some got through (perhaps whilst McAfee was disabled?) as my wireless internet dongle LED was flashing rapidly. I locked down my firewall and unplugged my dongle. I opened up McAfee clean up in an attempt to clean out anything that might still in my temporary files, I then regretted it as it also deleted all my system restore points. I opened task manager and recognized the names of many of the programs I had blocked internet access for and they were running. I clicked on the start menu then all programs and noticed there was a new folder called 'AV Care' I was also getting pop ups on screen telling me to scan. I closed these pop ups and ignored 'AV Care'. I brought up search and searched for any files with todays date. It appears that a number of files were modified and created at 14:49 and 14:50, the time of the attack, including 'AV Care' as well as some shortcuts to pornographic websites. Shortcuts such as Minesweeper were modified. After closing a few more pop ups I put my computer into hibernate mode, though it took an unusually long time to actually do it.
If you need anything else please let me know and thanks in advance.

Hi and welcome to BleepingComputer :thumbsup:

The process of cleaning your computer may require temporarily disabliling some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • 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 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 and exit MBAM.
Note:
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

Hello, thanks for your help. I downloaded the program and it's updates on a friend's computer (when I tried using mine I was bombarded with programs requesting internet access, my security being disabled, pop ups and sites refusing to display etc.) Once downloaded I took them to mine using a USB stick.
I ran the program and it found and removed 29 infected files. I restarted my computer as prompted.
Upon restart I was shown a Log on window I have never seen before. It had the user name already filled in.

User Name: Jestral
Password:

I've never seen this before but I tried all of my usual passwords with no success. Any ideas?

Can you post that log? I am not sure what opened that asked for a password.

You can also run this:
Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible. Some steps will require you to disconnect from the Internet or use Safe Mode and you will not have access to this page.

Please download DrWeb-CureIt and save it to your desktop. DO NOT perform a scan yet.

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

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. (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • After the Express Scan is finished, put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and unheck "Heuristic analysis" under the "Scanning" tab, then click Apply, Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • Please be patient as this scan could take a long time to complete.
  • When the scan has finished, a message will be displayed at the bottom indicating if any viruses were found.
  • Click Select All, then choose Cure > 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)

Hi Rigel, I've been having a few problems.
I tried again to access my computer with the same result, I couldn't get on because of the log on window. I later tried again with a different result: A new window appeared which read:

To help protect your computer Windows has closed this program:
Name: Userini Logon Application
Publisher: Microsoft Corporation

I closed the window and stared at a blue screen for a few minutes but nothing happened. I tied Ctrl + Alt + Delete and got:

To help protect your computer Windows has closed this program:
Name: Task Manager
Publisher: Microsoft Corporation

I eventually had to shut down my computer by holding down the power button.

I then tried starting up in safe mode.
I successfully logged on as administrator. I got to the desktop and opened Malwarebytes but the log was gone. McAfee was then 'unexpected shut down' and could not restart. I started a new scan with Malwarebytes but nothing was detected.

I haven't tried downloading DrWeb yet as I can only get onto my computer in safe mode and I'm concerned that using the USB stick I used before could infect my friend's computer, is this likely?

That is possible. Let me ask for some help with this.

Hi Rigel, I recently found an old back up disk that I made, I think that starting again with my back up would be a good idea. Would it be possible to completely wipe both of my hard drives? As I can only get as far the the welcome screen whilst not in safe mode I'm not sure if I can.

Do you have restore disks on hand? Or, are you speaking of reformatting and reloading?

Hi, sorry it's been a while since my last post, something came up.
I was talking about a doing a system restore, pressing F2 at boot up. It starts by formatting the hard drive then reinstalling the OS with factory set up.
I did this and everything seems to be working. I downloaded Dr Web and ran it in safe mode and no infected files were found. However, the computer is running a little slow and there are some programs running in Task Manager that look unfamiliar, though that may be paranoia. I haven't used my back up CD because if those files get infected then I will loose them forever.
Is it possible for viruses to hide from formatting?
