My Webroot software popped up that it detected a virus called Mal/FakeAvJs-A. It detected this same thing a few days ago and I quarantined it then deleted it. I thought it was taken care of until tonight. This same computer crashed about a month ago and I had to take it to a repair shop to get it to boot. They didn't say if it was infected or anything so I don't know if this is still the same problem as before? Please let me know what I can do to get rid of this! Thanks!

Hi and welcome.
Mal/FakeAvJs-A is a malicious script, usually found in a page pretending to relate to anti-virus software. The script will eventually try to download a malicious executable file, either by itself or by misleading the user. (Sophos)
I think we should get another scanner opinion,right!

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. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
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. 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 after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

Malwarebytes didn't detect anything with the Quick Scan mode so I went ahead and ran a Full scan. It says it didn't find anything there either but here is a copy of the results. Is this pretty accurate or do I need to run something else? Thanks!

Hi, please run another Webroot scan from safe mode and see if it still finds something. If so please note where it finds it and where you or it put it. Or post that scan log.

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.

Ok..I ran a Webroot scan in safe mode and it found another virus. It is in quarantine in Webroot now. In the quarantine, I now have 3 virus files in there. I have left them in quarantine until we decide what to do with them. Do I need to run Malware bytes in safe mode? My computer is now getting stuck rebooting if I have anything plugged into a usb. I have to leave the internet unplugged and let it boot up. Do you think this is part of the same thing? Thanks!

Missy

Hello it is possibly a hardware error. Are you getting an error message prior to the reboot.

Hi again! I figured out that the reboot problem is a hardware problem with my printer. I have gotten that fixed but I am still getting the virus notices. I have deleted them from quarantine but it keeps finding them. Do you think I need a hijack log or anything? My computer is running SSSOOOOO slow also. I ran another Malwarebytes today but it didn't find anything still. Thanks so much for your help!
