• Windows security updates knows about Anti - virus software

  When the updates are downloaded to Windows Defender, firewall and other things, it knock out my Antivirus Microtrend. Updates of Windows on my computer Vista firewall and Windows Defender interferes with my microtrend Antivirus software, so it no longer works?

  After the last update automatic this month by windows, my Microtrend disappeared completely and he worked since August 2011. I had to contact Microtrend and download everything again. Now I have to approve all of your updates, why is it happening?

  When my firewall is off, my computer automatically shuts down when I go on the internet why?

  This forum is for Microsoft Security Essentials.

  Since you use TrendMicro (Microtrend?), you really need to contact them for further assistance.

  You should not have more than one active anti-malware running program. It will cause conflicts performace issues and will result in less protection.

  Stand-alone on demand scanners is OK.

  If you use Microtrend (TrendMicro?), you should not run Windows Defender.

• How to uninstall printer driver that is not installed on the computer

  Original title: my "unknown device" is a printer I own is no longer!

  To solve the problem "code 28", I have to re - install the driver for HP OfficeJet Pro 8500 - but the printer is no longer installed, and in fact I is even more has the printer.  The HP printer appears on the screen "devices and printers", but when I click on the yellow triangle on my laptop device, it brings me to the unidentified printer and the hardware - MF\Officejet_Pro_8500_A910 & WSD & IP_PRINT ID.  How can I uninstall a printer that is not installed, or how can I update the driver on a printer that is not installed.

  Thanks for reminding me about MalwareBytes and SuperAntiSpyware.  I used MalwareBytes a few years ago to kill a particularly tenacious virus that prevented me from my virus program execution.  I ran the two--identified only 4 files MalwareBytes and removed and SuperAntiSpyware found 286 tracking cookies - I zapped them.

  Now, the best news of all...

  Child of a friend's House of the college - he won grants and national contest for his expertise in computers/software diagnosis and repairs as a sophomore in high school.  He stopped on the way back to decipher problems with computers on the local school district and spent every three minutes solving my problem.  I don't really know what he was doing - he did so quickly - but he said to send you the link and you will understand it better than I could explain it.

  http://www.howtogeek.com/HOWTO/Windows-Vista/remove-old-drivers-after-upgrading-to-new-hardware/

  The yellow warning triangle disappeared, and the unidentified printer is no longer there.

  I want to thank all those who contributed to this thread - your persistence and patience has been remarkable.  I learned a lot from the experience even if I was not able to completely solve the problem.  I congratulate you all.

• Firefox 5.0 disabled an add-on, which is associated with my anti-virus software. Is this disabled module if I use another browser too or just in Firefox?

  I just installed Firefox 5.0. I have also just renewed by subscription to Webroot Internet Security Essentials, so I have the updates on that as well, and apparently something in the latest Webroot is not compatible with the latest Firefox. When I open Firefox, I get a message that a Webroot 1.7 'Add-on' and a few files associated with Webroot (I wrote not them down and the error message disappeared) have been disabled. What worries me, because I do not know what part of my antivirus program has been disabled by Firefox. My Webroot reports that it is functional and up to date.

  What he says is that Webroot has a special add-on for firefox which does not match the version of firefox you have. Webroot will still work, but it will not use this special accessory. You may or may not have a similar attachment that it is bundled with other browsers. I'm not sure. All-in-all, the module is not the main part of your anti-virus, it's just a piece of bonus, they give you.

  Firefox has not disabled your anti-virus software, and using another browser will be no more or less dangerous than before that.

  Think of it as a vacuum cleaner. He always goes to the vacuum cleaner and clean, but the small fancy brush to clean baseboards or something does not fit immediately.

  They have most likely only need to change the small part of it that shows what versions of firefox, it will work with, if the chances are that if you keep an eye on, there will probably be an update soon with a version of the add-on that is compatible.

• What is the prevalence of viruses, malware, etc., to be hidden and undetectable by anti-virus software?

  • As before, when my computer when my computer has been infected, I get a svchost.exe error, repeatedly, whenever I restart the computer. The infection has been discovered that the last time by my anti-virus software, because it was hidden.  It was a computer expert on this forum who told me my computer was infected by svchost.exe repeated error messages that I received.  I ran my Avast software, anti-malware software from MSFT Security Center, Win Defender, etc. this time, and it has detected no infections.  (Yes, I know what to do to pass this message means not necessarily my computer is infected, but the tech guy said that it is likely, given that the error message appeared on several occasions).  How detect and destroy the virus/malware hidden, etc?
  • Also, if anyone can answer another question... I was told that it is not recommended that I have two programs of anti-virus software, which I do - Win Defender and Avast (I guess they may conflict).  I tend to want to keep Avast, but would like to know if I have to keep Win Defender instead, because it is a Win a Win system program.  If I've got this me getting rid of one of them, is it recommended that I both uninstall and then reinstall one of them?

  A person help would be appreciated!

  Thnx, Dharma

  WHAT I HAVE: Win XP Media Center, MS Office 7 Professional (used at home), IE8, Outlook 7, HP w / 32-bit dual core processor, latest version of Avast & Win Defender, Srvc Pack 2 and 3 (although I know that I don't need 3 because I have not upgraded to Win 7, but it won't let me uninstall it!) and regularly updates Win.

  PS Please ask questions if you have, before you answer, so it will be less likely that I'll get the wrong answers that don't relate directly my questions! (Can say you that has already happened?  (LOL).

  You pouvez have a type of rootkit of malware infection.  Rootkits can transform and change of identity on your OS (and are difficult to detect and remove) and many computing professionals recommend a reinstall of the operating system in order to ensure that the rootkit is removed.

  Follow the suggestions in the Brian - post.  The link that he provided is an excellent reference.   If you have a rootkit, TDSS Killer or one of the other programs listed pourrait be able to remove it.

  You can also:

  You can get free help in the removal of malware from MS Support here: http://supportservices.microsoft.com/support/services/virus_malware_removal

  If you are in North America, you can call the MS Support to 866-727-2338 for help with infections of virus and spyware.

  For international information see your subsidiary local technical support site.

  Or get assistance from Avast at: http://www.avast.com/support

  You have SP3 on your Win XP OS and if you plan to switch to Win 7 make sure that your processor and RAM will manage Win 7... with your history of technology issues a reformatting/clean install of Win 7 would be a good idea.  Because of the possibility of conflicts, I do not recommend using Windows Defender with Avast or any other resident AV program.  Suggest uninstall you Windows Defender in Control Panel.  MSE and several other AV programs require the removal of Windows Defender in XP (or disabling the Defender in Vista and Win 7).

  Kind regards...

  Where am I today? I can't always run antivirus software and my computer is currently not protected... online security with networking Mode.

  Any suggestions?

  You cannot save your programs - a clean installation wipe everything from the hard drive.  Programs need to be reinstalled (they cannot be copied or saved) - and you probably wouldn't do anyway because there is a good chance that some of the infected files can reside in these same programs.  The ONLY way to avoid this is to get your hands on a real Windows Vista Installation disc, so we can attempt a repair system/upgrade where your programs will be preserved (and we don't know yet if that will completely solve the problem of infection but it probably will restore the functionality at least for a certain period of time).

  Sorry for the bad news, but that's just how it is.

• 8 flow HP tablet 5901: anti-virus software HP Strem 8 model 5901

  I recently bought a Tablet HP 8 5901 flow.  She has Windows 8.1 on it.  I would like to install on it's free anti-virus software, but there are so many 'out there' that I don't know which one is better for this model of HP Tablet.  Therefore, I'm looking for a recommendation about which one would be a good choice for this tablet.

  Since all of your content is cloud-based storage, a separate anti-virus product is not really necessary. 8.1 Windows built in Windows Defender.

  the Windows firewall and use theres rather...?

  I wonder!

  Hello

  It would be unwise to try to start without antivirus/antispyware are has just too many real threats and
  methods for malware to attack the system. If you attempt to do if of course you have redundant and
  current backups.

  Here's what I use and recommend: (these are all free and very effective versions.)

  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 leave the file system, Web,.
  Operational network (Script and behavior are also recommended in Ver 6 +).

  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 6.x and 4.8 x

  Avast - home - free - 6.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/   <-->
  http://info.prevx.com/downloadcsi.asp  <-->

  Choice of PCmag editor - Prevx-
  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.
