edit. I posted this yesterday but in the wrong forum

Hi everyone,

Yesterday I my zonealarm went off and it asked if I should allow winav.exe, I immediately thought Ďoh no, lets hope this isnít a tough virusí unfortunately this one is a toughy and that is why Iím asking for advice here to see if anyone has come across the same symptoms as myself.

I would like to mention that I am not a complete noob but Iím no expert either. I was reading over some forums online on how to get rid of this fake antivirus virus and I got the following instructions:

Remove the following files:

C:/Doc and settings\ all users\ app data\ winav.exe

Reg:

Hkey_curent_user\software\winpc antivirus

Hkey_curent_user\software\microsoft\windows\currentversion\run\winpc antivirus

Hkey_curent_user\software\microsoft\windows\currentversion\ uninstall\winpc antivirus


Hkey_curent_user\control panel\ donít load\ scui.cpl & wscui.cpl

Hkey_curent_user\software\microsoft\windows\currentversion\run\sysav

Hkey_curent_user\softwarre\microsoft\security center \ antivirus disable notify

Hkey_curent_user\softwarre\microsoft\security center \ firewalldisablenotify

Hkey_curent_user\softwarre\microsoft\security center \ updatesdisablenotify

The bold are the ones that I could not find on my PC.

After a few freezes and restarts I finally didnít have the fake antivirus pop up. I was still having problems with the welcome screen. The PC freezes on that screen if there is not a 5-7 second break of having the computer completely turned offÖwhen I restart it usually gets stuck there. I ran AVG 8.5 and found Crypton in a lot of the win32 files. I was able to put them into the virus vault (then deleted them from the vault [not sure if thatís a good or bad thing] thinking AVG solved my problem) but it didnít seem to change much.

From what I read this is probably one of the reasons I couldnít get malwarebytes, combofix, super-antivirus to start upÖI couldnít even install malwarebytes because something was blocking it. I was also getting a freeze when opening up explorerÖthe iexplorer.exe file had Crypton by its name in the AVG scan I had run. Finally I decided to try out SDfix in safemode and it worked. I saved the log in case any Ďprosí can help me out. I can use the computer for a while now until it freezes again. I can use explorer, but if I open it up twice, the pc freezes. I can only use firefox for now.

Iím sorry if some of this is written in poor grammar and jumbled up, Iíve been trying to solve this issue for the past 9 hours and had no luckÖim tired, frustrated and hungry.

If anyone needs anything cleared up please feel free to ask and Iíll do my best. As for now Iím off to eat and sleepÖI just hope I can resolve this horrible virus problem and not have to format the whole systemÖ

Any help would be appreciated.

Hello bugzy,

Please tell us what your operating system is: Windows XP, Vista, etc.

From what I read this is probably one of the reasons I couldnít get malwarebytes, combofix,


Please note: ComboFix is an extremely powerful tool which should only be used when instructed to do so by someone who has been properly trained. ComboFix is intended by its creator to be "used under the guidance and supervision of an expert." It is NOT for private use. Please read Combofix's Disclaimer. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again.

Running ComboFix by yourself is like performing open heart surgery on yourself--the scalpel and other surgical tools that is ComboFix is meant to be wielded by a highly trained surgeon only in emergencies or dire circumstances. When the surgeon is thru s/he leaves the room. So combofix should be removed from a system once it has accomplished its job, unlike an AV that is there to protect you from future infections.

. . . CF does make some alterations to your system if you run it. Even if you had no malware removed and run the uninstall command, some things may be different now on your system. I can tell you that one thing is that all your restore points will be flushed out and a new one created. There is a good reason to do that when you have a severe infection--but if you aren't infected you might need those restore points.

Read and abide by the disclaimer people. It's there for a reason. Stick to running and protecting yourself with a good AV and firewall and an anti-malware scanner or two. If you feel you need a second opinion, try running online scans. If you feel you might need surgery, come here to BC and ask for help--that is what we're here for.

Are you/were you experiencing any pop-ups, redirections etc.? Please describe and be as specific as possible. If you are, do they occur only with IE or do they occur with Firefox as well?

Also, do you have access to another computer?

Also please run MBAM:
Please download Malwarebytes Anti-Malware (v1.36) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • 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.
