All https sites are routed to/from a site that has an 'invalid certificate' with the name DATAMARKETRESEARCHAPPS.

I just upgrade to v26 v27 and did a reset and had no problem before this.

Hello rehmeyer, this seems to be a problem caused by malicious software on your PC.

go to Control Panel / programs and remove all the toolbars, programs, suspicious or things you have not installed intentionally there.

afterwards, run a full scan of your system with security tools like the free version of malwarebytes & adwcleaner.

    You may have installed one or more variants of the malware "VSearch' ad-injection. Please back up all data, and then take the steps below to disable it.

    Do not use any type of product, "anti-virus" or "anti-malware" on a Mac. It is never necessary for her, and relying on it for protection makes you more vulnerable to attacks, not less.

    Malware is constantly evolving to work around defenses against it. This procedure works now, I know. It will not work in the future. Anyone finding this comment a couple of days or more after it was published should look for a more recent discussion, or start a new one.

    Step 1

    VSearch malware tries to hide by varying names of the files it installs. It regenerates itself also if you try to remove it when it is run. To remove it, you must first start in safe mode temporarily disable the malware.

    Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. Ask for other instructions.

    Step 2

    When running in safe mode, load the web page and then triple - click on the line below to select. Copy the text to the Clipboard by pressing Control-C key combination:

    /Library/LaunchDaemons

    In the Finder, select

    Go ▹ go to the folder...

    from the menu bar and paste it into the box that opens by pressing command + V. You won't see what you pasted a newline being included. Press return.

    A folder named "LaunchDaemons" can open. If this is the case, press the combination of keys command-2 to select the display of the list, if it is not already selected.

    There should be a column in the update Finder window. Click this title two times to sort the content by date with the most recent at the top. Please don't skip this step. Files that belong to an instance of VSearch will have the same date of change for a few minutes, then they will be grouped together when you sort the folder this way, which makes them easy to identify.

    Step 3

    In the LaunchDaemons folder, there may be one or more files with the name of this form:

    com Apple.something.plist

    When something is a random string, without the letters, different in each case.

    Note that the name consists of four words separated by dots. Typical examples are:

    com Apple.builins.plist

    com Apple.cereng.plist

    com Apple.nysgar.plist

    There may be one or more items with a name of the form:

    com.something.plist

    Yet once something is a random string, without meaning - not necessarily the same as that which appears in one of the other file names.

    These names consist of three words separated by dots. Typical examples are:

    com.semifasciaUpd.plist

    com.ubuiling.plist

    Sometimes there are items (usually not more than one) with the name of this form:

    com.something .net - preferences.plist

    This name consists of four words (the third hyphen) separated by periods. Typical example:

    com.jangly .net - preferences.plist

    Drag all items in the basket. You may be prompted for administrator login password.

    Restart the computer and empty the trash.

    Examples of legitimate files located in the same folder:

    com.apple.FinalCutServer.fcsvr_ldsd.plist

    com Apple.Installer.osmessagetracing.plist

    com Apple.Qmaster.qmasterd.plist

    com Apple.aelwriter.plist

    com Apple.SERVERD.plist

    com Tether.plist

    The first three are clearly not VSearch files because the names do not match the above models. The last three are not easy to distinguish by the name alone, but the modification date will be earlier than the date at which VSearch has been installed, perhaps several years. None of these files will be present in most installations of Mac OS X.

    Do not delete the folder 'LaunchDaemons' or anything else inside, unless you know you have another type of unwanted software and more VSearch. The file is a normal part of Mac OS X. The "demon" refers to a program that starts automatically. This is not inherently bad, but the mechanism is sometimes exploited by hackers for malicious software.

    If you are not sure whether a file is part of the malware, order the contents of the folder by date modified I wrote in step 2, no name. Malicious files will be grouped together. There could be more than one such group, if you attacked more than once. A file dated far in the past is not part of the malware. A folder in date dated Middle an obviously malicious cluster is almost certainly too malicious.

    If the files come back after you remove the, they are replaced by others with similar names, then either you didn't start in safe mode or you do not have all the. Return to step 1 and try again.

    Step 4

    Reset the home page in each of your browsers, if it has been modified. In Safari, first load the desired home page, then select

    ▹ Safari preferences... ▹ General

    and click on

    Set on the current Page

    If you use Firefox or Chrome web browser, remove the extensions or add-ons that you don't know that you need. When in doubt, remove all of them.

    The malware is now permanently inactivated, as long as you reinstall it never. A few small files will be left behind, but they have no effect, and trying to find all them is more trouble that it's worth.

    Step 5

    The malware lets the web proxy discovery in the network settings. If you know that the setting was already enabled for a reason, skip this step. Otherwise, you should undo the change.

    Open the network pane in system preferences. If there is a padlock icon in the lower left corner of the window, click it and authenticate to unlock the settings. Click the Advanced button, and then select Proxies in the sheet that drops down. Uncheck that Auto Discovery Proxy if it is checked. Click OK, and then apply.

    Step 6

    This step is optional. Open the users and groups in the system preferences and click on the lock icon to unlock the settings. In the list of users, there may be some with random names that have been added by the malware. You can remove these users. If you are not sure whether a user is legitimate, do not delete it.

  • I got a call from people claiming that there was a problem with the computer.

    Original title: scammed by PCWizards?

    A few days ago I received a call from PC assistants saying they were Windows operating system support. They tell me that they have noticed that I had many requests from spam junk that was slowing down my computer. Unfortunately, as I had a big problem with my computer in time, I bit. I was very nervous about it at the time, but since I had so many problems with my computer and that you didn't know what to do, I fell prey to their plot. They talked to me in a 6 month contract for a fee of $99.00. After they have finished the maintenance on my computer, it worked very well, too gullible me thought: maybe they are legitimate.

    At the end of the interview I googled their business and came across an article that has been exposed as the crooks and claims that Wizards PC installs a spyware sophisticated by giving them access to the victim's computer remotely.

    To reassure myself, I decided to call using my Norton Security System. Their technician checked my computer and found a few things that their technology did not that he should have done; such that no detected restore points, the registry was not cleaned (35 detected registry errors) and it did not remove some software malware browers (toolbars).

    On his recommendation, I recalled PC assistants. The first tech I talked didn't seem to know what he was doing, so I hung up with him and sent their support line and ask them to address these problems or I would withdraw the payment from my credit card. Almost immediately after sending the e-mail, another technician called me. Unknowingly, I had all ready filed a dispute with my credit card company. I intend to cancel the service, but I am still concerned by some spyware detected on my computer. What is the best way for me to handle this? How can I get authenic proof that I was definitely scammed and I should report it to the Internet Crime Center? Using my computer for a few basic daily functions, must not be so stressful!  Any constructive guidance would be greatly appreciated!

    It's a scam.

    Either these so-called "Microsoft" Tech companies want to sell you a worthless software, or remote access to your computer to try to steal your credit card and bank information and also achieve an identity theft on you.

    If you use your online credit card, cancel and get a new one issued to you.

    And the only way that willl you know that you are free to them is to backup your data and do a clean install of your operating system.

  • All https sites are with sec_error_untrusted_issuer and watch a specific certificate

    All https sites I visit will get "this connection is untrusted". I tried reinstalling (entirely) firefox and also uninstalled all kinds of virus software (I had Kaspersky Endpoint Security 10). Tried to clean the cache, cookies, history, and all temporary files disk cleanup. Also tried the file cert8.db regeneration and reset profile. Nothing seems to work, but on other browsers, pages Web (facebook, youtube, banks) work very well. What would be the next step to get closer to the solution. (Keeping in mind a constant restart was part of the process).

      • Also when I "Add Exception" and obtain the certificate, then it shows "thawte, Inc." on each site.

    For some reason any using CCleaner to clean my computer fixed the issue... While I used the disk cleanup to clean all my files, but if anyone has the same problem, then CCleaner would be an option to try.

    This happens since I updated from FF6 on all sites that use the protocol https for logging under... I contacted most of the sites and they say that's not them... they are all sites that I have seen in the past and regularly use... now since I updated to FF, they no longer work and I had to use another browser to access these sites... it's a royal pain!

    Thank you very much! Who has resolved, but is it safe to leave it off?

    Thanks again!

    Firefox blocks all https sites, I can not even my Google mail - there is no option to bypass this blocking!

    Or, I can simply go to http://google.mail.com... I don't see ANYTHING in the settings to disregard certificates

    Firefox has gone downhill the way in many ways...

    Tittiger said

    I respectfully disagree with you about Firefox...

    The code of Firefox is so bad that I only use it as a last resort. Constantly, it crashes and has done this on several PCs in 2 or 3 years.

    In any case thanks for the suggestions, but it turned out malware that Panda deleted.

    If Firefox is a 'last resort', why you use it to check your emails? Do you use Google Chrome to access Google mail? I've never had problems with Firefox, then maybe I'm just lucky.

    Added the: Chrome and IE are coded by companies funded by programmers. Firefox is a program open source funded through donations to not-for-profit, which means that's what users are doing. If the 'bad code' is probably just different, not bad.

  • All of my records changed in the files system and .exe files are created with the names of these folders.

    Is it due to malware? How to convert these files to their form of moose?

    Hi Raffey Hassan,

    ·         Did you do changes on the computer before the show?

    ·         You have security software installed on your computer?

    Changed file .exe file names, the reason might be that the computer is infected from virus or malware.
