How to prevent a Trojan horse to send e-mails

My Thunderbird sends spam to all my accounts. I want to stop it leaving ME ONLY to send, not an automated virus.

Or it could be something on your PC that isn't using Thunderbird. For example, a program (good or bad) has to do is open a port on an SMTP server and run the well documented Protocol. Sometimes, I sent emails in this way myself using telnet. (It's kind of awkward to do this way, but it shows that you don't really NEED an e-mail client to send emails).

  • How do you remove Trojan horse from the Windows\system\svchost.exe file located?

    How do you remove Trojan horse from the Windows\system\svchost.exe file located? I worked on this problem for 5 days. I've tried everything except wipe the hard drive completely and starting over. Windows xp pro sp3

    I bought a new diagnosis program and quarantined the virus once it has been identified. I tried to remove the virus in several ways, but it comes back. The best way that I thought would work enter safe mode and by changing the attributes of the svchost.exe file and then delete and checked the registry AWI hwo to the Web site, but it continues to be problematic.

    During the uninstallation of antivirus/antispyware/security programs always check for an uninstall

    http://KB.eset.com/esetkb/index?page=content&ID=SOLN146
    ------------------------------

    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/   <-->

    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.

    First of all, you must realize that truly control information is not a realistic proposition. People can photograph their screen, for example. Assuming that you accept the weaknesses, maybe the DRM is a possibility, although it sounds as if you need several administrators full time. Adobe LiveCycle Rights Management is a solution Adobe DRM generally used as part of a policy of control of company data - not ad hoc to solve simple problems - and usually something to get buy-in to the level of the Board of Directors.

  • How to remove a Trojan horse in Firefox, but OK in safe mode?

    For about three days each time I do a search on google and try to open a site I get redirected to a page called stepandomain.com
    If I'm fast enough I can right click and open site in a new tab. In safe mode, this happens. In Internet Explorer, it doesn't happen. I uninstalled and reinstalled Firefox. I use HP PC with Windows XP SP3.
    Help will be GREATLY appreciated. Thank you very much.

    As it does not occur in safe mode, check your extensions to see if one of them is the cause. For more information on how to do that see https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes

    Re-directions can be caused by malware. Try to run several malware scanners. It is better to run more as each will be looking for things that the other miss. Some scanners, you can try are:

  • How people make viruses, Trojan horses, worms, etc. ? __

    I didn't do this kind of form for years because I can just never get to work, but I think it's time I learned what I am doing wrong!

    "mailto:" is a command for your operating system open the default e-mail program.

    Contact forms are better handled by a PHP script or CGI - BIN script on the server.

    In addition, a "mailto:" is an open invitation to "spammers" who hit your site and suddenly you get all offers of credit to "good male enhancement drugs" report

    Check with your hosting service to see what they offer for contact forms. Most offer PHP or CGI - BIN form processing or support them as part of your package.

    You can also check out services like mycontactform.com dealing with PHP and the CAPTCHA for free or for a small fee if you have a lot of traffic.

  • I tried to post a coupon on xianet and my computer has been taken over by a Trojan horse.

    I tried to post a coupon on xianet and my computer has been taken over by a Trojan horse. My report says: Win32/fakeSysDef. He directs me to a data recovery site that charges $75 to solve the problem. No idea how to do to remove the Trojan horse?

    Microsoft support addressed my problem and Javier took control of it and solved the problem.

    It has been pretty smooth how I got the Trojan horse. When I tried to display a coupon, a dialog box came asking if I wanted to download a software. I clicked 'Cancel' and this is meant to 'run '. That's when all this started.

    Thanks for help.

  • After an automatic update of the El Capitan, initialize to send diagnostic request. Is this real or a Trojan horse?

    Auto-installé update for El Cap 10.11.2 12/17 unattended via usual application store auto-updated. When I opened to the top of the standby mode the MacBook was initially white Virgin, then spinning dot gray then the screen asking permission to send diagnostics to Apple and the developers. All looked for real, but it could be a kind of Trojan horse?

    Whether it's a major OS update, such as 10.11.1 to 10.11.2, it is legitimate.

    It will look as if you set partially up the computer again. Should ask you to allow the diagnosis must be sent, and then show a computer small logo that says: "Setting your Mac upward" with a few small "data bars" on the screen. I don't know why Apple did allow you to send diagnostics and set up your mac after each update. I guess they have to ask anytime you install new software to avoid any legal problems.

    Hello

    If you need search malware here's my recommendations - they will allow you to
    scrutiny and the withdrawal without ending up with a load of spyware programs running
    resident who can cause as many questions as the malware and may be harder to detect as
    the cause.

    No one program cannot be used to detect and remove any malware. Added that often easy
    to detect malicious software often comes with a much harder to detect and remove the payload. Then
    its best to be thorough than paying the high price later now too. Check with them to one
    extreme overkill point and then run the cleaning only when you are sure that the system is clean.

    The methods below are for Windows 7 - Vista is very similar - for XP using RUN instead of
    Start - Search,.

    It can be made repeatedly in Mode safe - F8 tap that you start, however, you must also run
    the regular windows when you can.

    TDSSKiller.exe. - Download the desktop - so go ahead and right-click on it - RUN AS ADMIN
    It will display all the infections in the report after you run - if it will not run changed the name of
    TDSSKiller.exe to tdsskiller.com. If she finds something or not does not mean that you should not
