Why don't all Microsoft security tools detects nothing, while others?

• Firefox opens, running Microsoft Security Essentials & Malwarebytes, nothing coming.

  I have 18 installed Firefox. This is the third time that Firefox has stopped opening.

  I ran Malwarebytes and Microsoft Security Essentials all three times and each time found any problems. The only thing that worked was (using Revo Uninstaller) uninstalling and reinstalling.

  It has worked well for three weeks and stopped opening again last night.

  Oh, and attempt to use the mozilla help screens in Internet Explorer is a nightmare...

  And I tried to use the troubleshooter below, IE won't let either.

  One possible cause is security software (firewall, antivirus) that prevents or limits Firefox or plugin-container process without informing you, possibly after the detection of changes (update) for the Firefox program.

  Delete all rules for Firefox and the plugin-container in the permissions list in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

• Why Microsoft Security Scan detects TrojanSy:win32 / Banker.SW but do not delet it

  I have the scanner provided by Microsoft, itdetects TrojanSy:win32 / Banker.SW, but do not delet it, WHY IS the following, AND WHAT to DO to DELET THIS VIRUS

  Download the free version of this tool. Look for updates and do a quick scan first. It will take a few minutes. She will most likely find the Trojan horse and allow you to remove it, but make a full analysis later to be sure. It will take 1 ~ 2 hours.

• Why do I need Microsoft security updates when I have another installed security program. That is to say; Norton?

  Are updates necessary security when I run Norton Antivirus?

  Yes, you need both.

  Updates to close vulnerabilities in the system of Windows OS (& other Microsoft programs). Programs such as Norton to prevent you get viruses - for example by downloading or via a USB flash drive.

  You should also check that you have a firewall in place as well.

• Microsoft is aware of a rogue security alert that mimics alert Microsoft Security Essentials?

  See this site for more details.

  http://Clubhouse.Microsoft.com/public/post/001648ea-976f-4cfa-A528-0e4ffe23a8ec

  I was wondering if Microsoft knows about this threat.

  If Microsoft knows about this alert, how they classify this threat? What they call it?

  I know that no anti-virus software will detect all at the same time, I only meant that Microsoft should be aware of this, because the creators of thugs try to imitate Microsoft Security Essentials alert them and attract users in the purchase of products not authorized.

  I know how to check whether or not the alert is Microsoft Security Essentials.

  When the time protection real Microsoft Security Essentials detects something, it always appears from the tray icon, it shows not directly from the alert, whereas the fake one appears directly on the center of the screen of the computer.

  Anyway, the whole point is that I don't want too many antispyware software on my computer, I prefer to use portable applications for the detection and removal, such as rescue of vipre, portable superantispyware, doctor web cureit, norman malware cleaner. I don't want to have separate antispyware software more, that drives me crazy, if I have these installed I will need to be updated regularly, they don't have no automatic updates unless if I buy the full version.

  I know that it will be easier to tell if the alert is false or not, once Microsoft Security Essentials 2.0 is installed on the computer, because Microsoft has removed the "Clean computer" button in alert details, it does appear on the alert since the icon of the status bar, while the false, they imitate the alert from MSE version 1.

  Maybe the alert doesn't really matter, the thing that matters is the threat to which the alert draws in

  Well, it seems that now, Microsoft has finally got the hang of this threat, the threat is now classified as Rogue: win32.fakepav

  Hope that Microsoft Security Essentials 2.0 coming out soon, so the user can make the distinction between the legitimate and the fake more easily alert.

  Do the following and check:

  Step 1:

  Try to do a Scan of the SFC (System File Checker). The scan will look bad system files and will attempt to fix them, if possible.

  (a) click the Start button.
  (b) type: cmd.exe in the search results.
  (c) right click the cmd.exe file and select 'run as administrator '.
  (d) in the CMD window, type: sfc/scannow and press the Enter key.
  (e) restart and see if that solves the problem.

  How to use the System File Checker tool to fix the system files missing or corrupted on Windows Vista or Windows 7

  http://support.Microsoft.com/kb/929833

  Step 2:

  If the problem persists, you can also scan your computer the Microsoft Security Scanner, which would help us to get rid of viruses, spyware and other malicious software.

  The Microsoft Security Scanner is a downloadable security tool for free which allows analysis at the application and helps remove viruses, spyware and other malware. It works with your current antivirus software.

  http://www.Microsoft.com/security/scanner/en-us/default.aspx

  Note: The Microsoft Safety Scanner ends 10 days after being downloaded. To restart a scan with the latest definitions of anti-malware, download and run the Microsoft Safety Scanner again.

  Note: The data files that are infected must be cleaned only by removing the file completely, which means that there is a risk of data loss.

  Hello

  Yes, you need to install all the applicable updates such as those that will enhance the functionality of the
  computer and also help to ensure his safety.

  =============================

  MSE is an excellent antivirus/antispyware software.

  Here's what I use and recommend:

  Avast and Prevx proved extremely reliable and compatible with all I have
  launched on them. Microsoft Security Essentials and Prevx have also proven to be very
  reliable and compatible. Use MSE or Avast and Prevx, Prevx 3 but not all.

  Avast Home free - stop any shields is not necessary except leaving Standard, Web, and
  Operation of the network.

  Prevx - Home - free

  Windows Firewall

  Windows Defender (is not necessary if you use MSE)

  Protected IE - mode

  IE 8 - SmartScreen filter WE (IE 7 phishing filter)

  I also IE always start with asset if filter InPrivate IE 8.
  (It may temporarily turn off with the little icon to the left of the + bottom
  right of IE)

  Two versions of Avast are available 5.x and 4.8 x - use only and no if using MSE.

  Avast - home - free - 5.x stop shields you do not use (except files, Web, network, &)
  Shields of behavior) - double click on the icon in the Notification area - real time Orange - click on the
  Shield that you want to stop - STOP. To stop the Orange icon to show an error indicator-
  Click on the Orange icon - top right - settings - click on the status bar - uncheck shields you
  disabled - click OK
  http://www.avast.com/free-antivirus-download

  Avast 4.8 x - home - free - stop shields, you don't need except leaving Standard, Web,.
  and the network running. (Double-click the blue icon - look OK. - upper left - Shields details
  Finish those you don't use).
  http://www.avast.com/free-antivirus-download#TAB4

  Or use Microsoft Security Essentials - free
  http://www.Microsoft.com/Security_Essentials/

  Prevx works well alongside MSE or Avast

  Prevx - home - free small, fast, exceptional protection CLOUD, working with other security
  programs. It is a single scanner, VERY EFFICIENT, if it finds something come back here
  or use Google to see how to remove.
  http://www.prevx.com/   <-->

  PCmag - Prevx - Editor's choice
  http://www.PCMag.com/Article2/0, 2817,2346862,00.asp

  Also get Malwarebytes - free - use as scanner only. If you ever think malware and that
  would be unusual with Avast and occasional Prevx running with the exception of a low level cookie
  (not much), to UPDATE and then run it as a scanner. I have a lot of scanners and they
  never find anything of note that I started to use this configuration.

  Hello

  In Windows 7, the AllUsers folder is not a real file.

  It is a symbolic link that redirects to the C:\ProgramData folder.

  ProgramData is not hidden, by default.

  The correct syntax for the Attrib command would be,

  C:\>attrib h ProgramData

  You can view all files by going to the tab options\View Organize\Folder and research.

  In the section files and hidden files , place a check mark in the Show drives, folders and hidden files.

  This message is not in MSE. If you have an AV/program installed (AND you can), update the latest definitions, start in safe mode (without network), and then run a full scan. I would hazard a guess that you have downloaded something in this setup.exe which is not really a program AV. It would be likely to send all your personal information, including passwords and account numbers, to someone you definitely don't want it to be.

  If you do not have an AV installed, follow these tips:

  Download, install, execute, update and perform analyses complete system with the two following applications:

  * MalwareBytes (FREE) http://malwarebytes.org/mbam-download.php>
  * (FREE) SuperAntiSpyware http://superantispyware.com/downloadfile.html?productid=SUPERANTISPYWAREFREE>

  Delete all what they find, reboot when necessary. (You can uninstall one or both when finished.)

• If running Microsoft Security Essentials do I need run Windows Defender? Is the reason why I can't start the Defender-Essentials?

  I use Microsoft Security Essentials on Vista x 32.  Security Center tells me to start Windows Defender.  I click to start, but he tells me that I have to restart my computer or manually start Defender myself.  I go to services, and it does not advocate.  It basically tells me that my system has no need currently the program or there is another reason, it does not start.  Responses tells me that for the error code of course, I met error 0x800106ba later Code it tells me to try to start it manually if it doesn't work I have uninstall Defender and need to reinstall it.  Yet when I go to uninstall programs, Defender is not listed.  I tried to install it again because it is not listed, I thought I could.  When I went to install it, it-error telling me that I have already as it came pre-installed with Vista.

  Now, my question.  Do I really need Defender since I use Microsoft Security Essentials?  Is in fact an older version almost essential?  Why it tells me to start it if it is not needed? And if necessary, why it won't start

  Maybe something here if necessary:

  What is display / causing the error message? Some anitvirus/security/antispyware products can
  cause this error. On those who use you, including those that your never had even those
  uninstalled (the remnants can cause problems). McAfee is just an example of what many can do.

  Start - type in the search box - Services - find top - Right Click - Run as Admin

  Windows Defender - value STARTED and AUTOMATIC

  or set MANUAL and STOPPED if necessary
