Firefox, Internet Explorer, Chrome and Thunderbird are suddenly not opening

[headscratch71]

I'm running Windows 7 (64 bit) and turned on my PC this morning to find Firefox wasn't opening, I then tried my other browsers and nothing either.. They simply don't open at all. Here are the things i've tried along with many reboots:

Avast full system scan
AVG full system scan
Uninstalling and reinstalling the programs
Malwarebytes (did not run in safe mode however)
SUPERAntiSpyware

I've also checked and none of the programs are running in the task manager.

All of my other programs still open just fine, but anything to do with browsing/email doesn't open at all.. so i'm assuming this could be Malware? If not, then it must be something which all of these programs need to function. Could a certain missing .dll file be causing this? Something missing from Appdata? What else could I check?

I uninstalled/reinstalled Java, hasn't changed anything.

Would really appreciate a fix which doesn't involve reinstalling Windows, I have so many important programs installed for work and need it all at the moment. Any suggestions would be much appreciated, thank you

The first step is to uninstall one of the virus programs, would recommend AVG. You can't have 2 virus programs installed at the same time. Yes, this could be a malware issue. Please follow these directions and post the required logs.

1.

Please download AdwCleaner by Xplode onto your Desktop.



•Please close all open programs and internet browsers.
•Double click on adwcleaner.exe to run the tool.
•Click on Scan.
•After the scan you will need to click on clean for it to delete the adware.
•Your computer will be rebooted automatically. A text file will open after the restart.
•Please post the content of that logfile in your reply.
•You can find the logfile at C:\AdwCleaner[Sn].txt as well - n is the order number.

2.

Please download Junkware Removal Tool to your desktop.

•Shutdown your antivirus to avoid any conflicts.
•Very important that you run the tool in this manner:
Right-mouse click JRT.exe and select Run as administrator
Do NOT just double-click it.
•The tool will open and start scanning your system.
•Please be patient as this can take a while to complete.
•On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
•Post the contents of JRT.txt in your next message.

3.

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

• Double-click mbam-setup.exe and follow the prompts to install the program.
• At the end, be 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. Please keep updating until it says you have the latest version.
• Once the program has loaded, select Perform quick scan, then click Scan.
• When the scan is complete, click OK, then Show Results to view the results.
• Be sure that everything is checked, and click Remove Selected.
• A log will be saved automatically which you can access by clicking on the Logs tab within Malwarebytes' Anti-Malware

If for some reason Malwarebytes will not install or run please download and run Rkill.scr, Rkill.exe, or Rkill.com. If you are still having issues running rkill then try downloading these renamed versions of the same program.

EXPLORER.EXE
IEXPLORE.EXE
USERINIT.EXE
WINLOGON.EXE

But DO NOT reboot the system and then try installing or running Malwarebytes. If Rkill (which is a black box) appears and then disappears right away or you get a message saying rkill is infected, keep trying to run rkill until it over powers the infection and temporarily kills it. Once a log appears on the screen, you can try running malwarebytes or downloading other programs.

Please post the log that Malwarebytes displays on your screen.
