Windows Defender Gone Due To Trojans Attack - How To Get It Back And Running
Apr 5, 2012
I lost Windows Defender. I had a few Trojans pop in last week. It was the Sirefef.p, and a few others I can't remember their other names. I think I have gotten rid of all of them. Now just trying to get back what they took. I had an Error code "0x80070424" with my Firewall. I followed these instructions here: [URL]. My Firewall is back up and running now. But my Windows Defender isn't working. It isn't even in my PC any-longer. These Trojans even uninstalled my Microsoft Security Essentials. But I got that reinstalled. I just need to know how to get my Windows Defender back up and running. I am using Windows 7 Home Premium.

ive been looking all over google and all i found was that winlogin.exe is a randex/RBOT virus (i honestly dont know what that means) but i could not find any solutions on how to get rid of it. Ive deleted it from my startup programs but i still think its somewhere in my computer and i cannot find it. Windows Defender will not turn back on, it freezes when i try, but windows firewall is still working. can anyone give me a fix PLEASE? i really dont want to restore my computer to that long ago or reset it completely, unless its the ONLY choice.

I recently had some problems in my windows. Out of many problems in windows 2 were that windows update was not working and secondly dialogue boxes did not have texts on it. I ran a quick WDO on windows from Boot and the scan was successful. It found some Malwares and removed it aftet which the above 2 mentioned problems ran away.. But; when I did a full Scan so that problems completly eridate away; BSOD occurred and could not complete the task.. I tried it twice an both the times same thing happened..

Bought my new ASUS laptop from Best Buy a week ago. Finally having a chance to get started with it. They gave some good advice, to create a back up disk(s) in case any issues arise. This means I will have to get a USB-operated external DVD drive. Not really a problem, I mean I don't mind doing that. But is it not possible to create the same backup disk on a flash drive?

I am trying to setup a Win7 Pro PC backup so that the primary user does not have any admin rights. Setup Standard user login and then another separate login for file backups.
Created a new login called Backup1, and assigned this User Account to the Backup Operators Group, and Users Group. Rebooted, and logged in as Backup1. Attempted to run Backup.

I am on a large LAN that I absolutely cannot disconnect from. I am using Windows 7 Home Premum with the latest updates. I use Comodo Internet Security (AV and firewall). Here is the problem: I am being hacked from the LAN level. What can I do to lock down my OS and minimize my attack surface? My Macbook doesn't succumb to this, but my fully updated Windows 7 PC gets hacked relatively easily from other users on the same LAN. I am experiencing remote code execution (IE9), unattended installs and system wide changes. What can I do to minimize my attack surface?

I have Windows 7, Premium Home Edition. When I typed Ctrl+Alt+Delete, I used to get the Task Manager. Tabs allowed me to select some options, one of which was "processes". Maybe I clicked something that changed things, but now I only get a list of running programs (NOT processes). And I don't have any tabs to select other options,How can I get the running processes list back?

Yesterday I was attacked by the s.m.a.r.t. trojan which has "hijacked" my files and hid them. I have followed the recommendation from Microsoft Answers, Security Essentials[URL] but it is not working. I got my desktop icons to show up but the screen is still black and I cannot see anything when I click the start button. It was suggested that I open up a new window in task manager, but when I click on Task Manager it reverts back to the fake virus scanner (S.M.A.R.T. HDD). I typed in "cmd" on the search bar, which opened up a dos prompt. I then proceeded to type in the following:
CD/ then hit enter
ATTRIB -H -R -S /S /D then hit enter
The prompt began to scroll through numerous files rapidly, but each line was preceeded by "access denied". So, when it finished, nothing was accomplished, as far as I know. I have not rebooted the PC yet. Any suggestion? I don't know if this was the incorrect thing to do, but, before I entered those dos commands I ran a copy of Windows Defender Offline Beta from disk. It said that it removed numerous trojans, but I fear that it only angered it. I will probably reformat my c:\ drive, b ut i want to gbet some files off of it prior to doing so.

I know there are few Limited connectivity threads but ive checked them, non of them have the answer im looking for so ill just tell you the story.I accidentily downloaded a malware/adware program called Antimalware Doctor, i tried going into safe mode and using multiple programs to delete it (Malware bytes, Spybot - Search and Destroy & AVG command line scanner) they apprently deleted it , i loaded my comp back to normal mode and there it was back in there corner >
i managed to get rid of the program by bringing up task manager and removing the process called "sorttm700" (thats what the antimalware doctor program was called in the toolbar when i hovered over it) then going to my computer and searching for sorttm700, i deleted all the folders with sorttm700 in them and rebooted and no more annoying ads to buy fake software however i still have limited connectivity (it became limited while the malware was on my computer and before i took any action to resolve it)i am trying to use the same network as the computer i am using now ot send this message, i never get connection problems with my laptop using this connection i have tried reseting my router and modem as well as uninstalling the driver and reinstalling and now there is a red cross with no options to connect to an access point, my wifi on my laptop is on before you ask?

I am trying to turn on Windows Defender with no success. I click on the works turn on Windows Defender but it just keeps going on and on. I tried downloading it again with the wizard but it said it said the wizard was interrupted and try again when I do it does the same thing. i tried downloading it from the Windows site and after downloading the pop up said "You do not need to install this software because Windows Defender is included in Windows Vista (I have Windows 7) You can access Windows Defender from the security section of the Windows Control Panel". Again, I tried this but when I click on the words "turn Defender on" it just keeps going on and on without doing anything.

I am using 7 for the first time today - I was downloading Alvira anti-virus and was asked to disable Windows Defender. It said something about tools - options etc, but the only place I would find Windows Defender was in the program files and nothing about tools etc. Noting in system tray either.

Windows Defender. This program is turned off. If you are using another program that checks for harmful or unwanted software use the Action Center to check that program's status. If you would like to use this program click here to turn it on.I've tried so many things I'm running out of patience. There seems to be nothing in Action Center that is relevant and I can't uninstall Defender as there's no option so I went to Services and disabled it. Still I get the message. I've tried a Command Prompt that should have disabled it, but no luck. I went to the AVG forum which is definitely not user friendly. I rang the free phone number only to find that a) I couldn't hear the operator and she couldn't hear me and b) it's only the phone call that's free - the service isn't.

Need to install Kaspersky internet security 2010 3-user before i go internet with new machine.reading the literature on this site and following it to the letter, i have been trying to disable windows defender but no joy.WHAT I HAVE DONE1. msconfig - there is nothing at all under 'startup' but found it in 'services' tried to 'stop' but theres a note that says some important windows services cannot be disabled. what? that cant be right.
2. Opened defender panel and tried to go Tools , Options but i cant, no manipulation of any of the options is allowed from the defender menu, it seems to be waiting for me to download updates from the net. (No way jose until i got kaspersky on it!)3. ctrl+alt+del, Task Manager, Services, found defender, right click to stop service and window pops up to say 'Operation cant be completed, access denied' . I am administrator as there is only one user.4.am looking for this services.msc but i cant find it. what is it?

restoring Windows Firewall and Defender. I am running Windows 7 64 Bit. A few weeks ago I was infected by a trojan called "System Progressive protection". I used an uninstall guide for removal but I am unable to enable Windows Firewall and Defender. I get Error 0x800070424 whenever I try to open either Windows Firewall and Defender.
I am currently using anti-virus software provided by my internet service provider, but I would still like the option of having Windows Firewall and Defender available to me.

I am using Windows 7 on my desktop and laptop.At the end of each week I run Malwarebytes and Superantispyware.I can no longer open Windows Defender unless it has an icon with a castle and blue flag? Microsoft security essentials is running and it says Real time protection on Virus and spyware definitions up to date.Is that enough protection or should I be running another anti virus program?

I am running Windows 7, 64bit with 12 GB of RAM. My memory usage is usually around 2-3 GB. About once a day, Windows Defender eats all my memory. For a few minutes the computer is slow (even if running i7-980) then Defender releases the memory and everything is back to normal. I know it's Windows Defender because as soon as I see memory going high, if I stop the Windows Defender service, the memory goes right back to normal.
Is there anything I can do except disabling the service?

Win 7 professional 64 SP1 all patches applied till today. Some days ago I got a Definitions Update, like many others before. But this time it failed to apply with an numeric code. Since I don't have MS Security Essentials (never installed it for what I can recall) and just have free Avira, Spyware Blaster and Malware Bytes, it should not be disabled or something. After reading a number of posts on the MS forums I tried manually starting the defender service, which failed with error 126 (could not find its mpsvc.dll DLL).
I noticed the required DLL, along with a couple others, was in Program Files, while the registry entry for it was set to %ProgramFiles (86)%\Windows Defender\mpsvc.dll. Not willing to fiddle with the registry, I just applied a .reg fix others on the MS support forums found useful to fix this issue with. But it did not help. The definitions update indeed worked but now the defender service won't start at all and shows as disabled (trying to start it does nothing, no error, no Windows logs in events viewer.

Got the Alureon.a trojan/rootkit. Downloaded the Windows Defender Offline and ran it successfully, but now I can not get past the "Verifying DMI pool data....".I've read countless posts about doing F8 or F10 to go into Advanced Boot Options, but neither of those respond. So I can not change the /NOEXECUTE=OPTIN.Only things I can go into are the Boot Menu (F12) and BIOS Setup (Del). I've tried every possible combo of Alt+F10, Ctrl+F8, etc. to no avail. Hitting (ESC) to go into Safe Mode option does not work either. Nor vigorously tapping of F8 or F10.

a while back, my computer was infected with a windows antivirus... virus. Essentially, it took over the windows defender and warned me about fake viruses so that it could get me to download more. I was able to clear that up on the bleepingcomputer forums, but was told to go elsewhere to fix my updater and defender. I'll post the link to that old thread, but first I'll post your standard info...
