Proxy setting has changed

Hello

I was with my Macbook Pro running Windows 7 on it in analogies, 2014 and all of a sudden, I could not access all Web sites via http. I quickly realized that the https sites were working, but with http traffic, I'd get a failed Proxy error. I went to my network settings and a power of Attorney had been implemented for 127.0.0.1 for http traffic port 62123.

I'm quite positive that I have not configured who, so I wonder how that could have happened. Looks like some kind of Malware?

Any comments would be appreciated!

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.

VSearch malware tries to hide by varying names of the files it installs. To remove it, you must first identify the naming model.

1 triple - click on the line below on this page to select, then 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. Search inside the files with a name of one of these forms:

com.something .net - preferences.plist

com.something.Preferences.plist

Here, something is a string, which may be different in each instance of VSearch random meaningless. So far it has always been an alphanumeric string without punctuation signs, such as "disbalance" or "thunderbearer."

You may have more than one copy of the malware, with different values of something.

There may be one or more files with the name of this form:

com.somethingUpd.plist

where something may be a different meaning empty string in other files. Yet once, there may be more than one file of this type, with different values of something.

Here is a typical example of an infection VSearch:

com.disbalance .net - preferences.plist

com.thunderbearerUpd.plist

You will have files with similar names, but probably not identical to these.

If you feel confident that you have identified the above files, back up all data, and then drag the files - nothing - to the trash only. You may be prompted for administrator login password. Close the Finder Windows, and then restart the computer.

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 and runs without direct user intervention. This is not necessarily bad.

2 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

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.

3. If you do not find the files or you are not sure about the identification, after what you have found.

If in doubt, or if you have no backups, change nothing at all.

4. the trouble may have started when you have downloaded and run an application called "MPlayerX." It is the name of a legitimate free movie actor, but the name is also used fraudulently to distribute VSearch. If there is an element with that name in the Applications folder, delete it. I do not recommend to install the genuine "MPlayerX", because it is hosted on the rogue 'SourceForge' site and is bundled with other malware.

This Trojan horse is often found on the illegal Web sites that traffic in content such as movies pirated. If you, or anyone else who uses the computer, visit these Web sites and follow the instructions to install the software, you can expect more of the same and worse, to follow. Never install software that you downloaded from a bittorrent, or which has been downloaded by someone else from an unknown source.

In the aspect of security & confidentiality of system preferences, select the general tab. The marked anywhere radio button should not be selected. If this is the case, click the lock icon to unlock the settings, and then select an other keys. After that, do not ignore a warning that you are about to run or install an application from an unknown Director.

Then, still in system preferences, open the pane of the App Store or software update and check the box marked

Install the system data files and security updates (OS X 10.10 or later version)

or

Automatically download the updates (OS X 10.9 or earlier version)

If it is not already done.

  • My address bar search has changed and it's really annoying.

    Hello.
    Today, my firefox has changed something in the address bar search system.
    Now the first link it provides is for "popular sites" or your partners no idea but it's boring as hell.
    He destroyed all my combinations of site search...
    When I wrote normally shortcuts like 'pwn' 'kol' 'da' for my sites now the first link provided to ask me "want to pwn/kol/da search in google? Dailymotion? »
    No ffs I don't want that. If I wanted to, I would use the search bar.
    I tried to fix it but can't find it in the normal options and won't play with the config of my own.
    Where I can it turn off? I can't stand it.

    You can set browser.urlbar.unifiedcomplete to false to remove the suggestion to visit the location bar page menu drop-down.
    Note that the sound is not really new, but it has now enabled by default in Firefox 43.

    You can open the topic: config page via the address bar.
    You can accept the warning and click on "I'll be careful" to continue.

  • The number of thumbnails on my new tab page has changed

    When I changed my PC switched off last night, my new tab Firefox page had twelve miniatures, four per line in three columns. When I turned on my PC today, I opened a new tab page and there were only eight vignettes showing, four per line, but only two lines. I haven't changed my setting in my sleep, so why has the layout has changed and how can I go back to the way it was? Change the zoom on the new page of tabs, to 80%, allows me to display 15 miniatures (I don't really want to fifteen just my twelve original) but only on that specific page, if I open a new fresh tab page is back to the display of thumbnails only eight again.

    Hi, as you know you can change the number of tiles on the new tab in the zoom Page forward or back.

    You also said keep the same zoom setting when a new tab is clicked: Type Subject: config in the address bar, press ENTER, accept the warning, scroll to browser.newtab.preload and double-click on it to change the 'value' of true to False.

    It is also possible about: config to change the maximum number of tiles, scrolling to the browser.newtabpage.columns (or Rows), then right-click > modify to set a new number of 'value '.

    As an alternative, you might like to try the add-on new tab tools.

    If your question is resolved by this or another answer, please take a minute to let us know. Thank you.

  • Suddenly I do not get the popup "Download finished" at the bottom of my screen when I download anything... in addition, download 'box' at the top left has changed... Why?

    until yesterday, whenever I want to download anything, I'd get a 'popup' in the bottom right of my screen saying "full download"... now I don't see... also, when I click on my download option in my 'tools' at the top on the right, the box that appears has changed how it looks... It still shows my downloads, but the appearance of the box has changed... None of these problems is all 'biggie'... lol... nothing to worry about... but I just want to know why it happened all of a sudden if I've made any changes to my firefox... anyone?

    The user interface for changed in 20 of Firefox downloads. There was a parameter, you can change all: config to restore the old style. That setting in Firefox 20-25, but was no longer exists in Firefox 26. So, you probably changed this and now know the standard interface.

    If it's your computer, then bring it in a store and see if they can reformat the drive and reinstall Windows, or otherwise bypass.  They can at least copy the data on the hard drive.  If someone did something, you probably will never know with certainty what, it is best to reinstall the software.
