How can I determine that trusted root certificates in the Certification authorities are all valid

I was looking in the Lenovo Superfish Adware (I have her, much less a Lenovo) and I read an article in PC world who said Superfish installs a root certificate self-produced in the Windows certificate store for trusted root Certification authorities, and then quit all SSL certificates, presented by the HTTPS sites with its own certificate :

http://www.PCWorld.com/article/2886278/how-to-remove-the-dangerous-SUPERFISH-adware-presintalled-on-Lenovo-PCs.html

This led me to run certmgr.msc (Certificate Manager) on my PC to see what certificates were in CAs roots of trust and to my surprise there are 321 certificates listed. How can I determine that all these certificates are all valid?

I use Kaspersky Internet Security 2015 and Windows Defender and update the definitions and conduct analyses regularly, with negative results. I have no problem at all with my PC, I'm just worried.

Hello Josagan,

Thanks for posting your question on the Microsoft community.

I understand your concern.

This request fits better to the MSDN forums since it is linked to the development of Windows.

I suggest you post your question on the following MSDN forum.

  • How can I determine that my writing pad out to a channel feature works?

    Hello

    So I created a ramp function using a loop that takes the difference between initial and final pressure value, divide by an integer (called time on VI) and then increments the value by the result, until the final value is reached. The initials + increment values are stored in an array, which I can write in the NI9263 channel.

    The question I have is that how do I know that the write function writes each of the values in a table, for each piezo the piezo. That is to say, so that if my output voltage 1V, the increase is 0, 5V and the final value is 3V, how can I check that all the values [1,1.5,2.0,2.5,3.0] are written in the channel individually.

    The current result I have seems to indicate that the write function resembles the initial and final values and jump between the 2.

    I enclose a copy of the VI (pardon the background image) and a graph of the results that I get, which is a smooth curve (as oppsed to a graph of type staircase that could be expected with a ramp function, showing discrete steps]

    I look forward to any help you could give me.

    Rather than put a graph put a 2D scoreboard and check that the two values are the mapping very less select sample rate as 1 sample per second and use finished sampling rather than continuous sampling.

  • How can you say that in your team is the purchase of photos?

    I have a team of 3 people with two accounts who have 10/m. subscriptions the idea was that everyone would have access to the purchase of 10 images per month. Someone claims that they bought only 2 images and they are up to 5. My guess is that the credits are actually shared within the Group and the other person actually used funds that were not under their account. So the question is how do I know who is buying what images?

  • How can I determine what my CURRENT profile, because the Profile Manager shows 3 and all the questions and answers are ambiguous on this issue. THX.?

    Yes, I see ambiguity. I have also some old Save profiles of boards and I have 3 profiles showing under the Profile Manager. The folder under "%APPDATA%\Mozilla\Firefox\Profiles\" shows 2 of them, but how DO I know WHICH is my current profile? So far, I have been unable to navigate up a clear answer. THX.

    You seem to have created a profile in the Profiles folder and not as you should be in an empty folder.

    You already clicked the button Choose a folder and specified the profiles folder in the profile folder?

    You must always specify an empty folder and new for the profile if you really want to create one profile other than suggest Firefox (you can change the file extension part after the '. ': for example the default user-> my < name >)

    It would be preferable to cleaning the Profiles folder and delete all the files except the file profiles.ini and the default and files 'default user', although you might want to move to another location and start from scratch. If necessary, you can retrieve data from one of the two folders.

  • How can ensure me that I am connected to the Wan, not the Base Station?

    I have one extreme as a base station, with an express the upstairs of the extension of the network. There are green lights on both, the utility displays the Express connected to the extreme and it is not a big house, so it seems that the network is configured correctly.

    However, when I'm near the Express, my MacBook Pro connection speed is significantly slower: 9Mbps, vs 30Mbps when close to the extreme. As far as I know, I am always connected the low extreme, rather as the Express I sit beside.

    Is there a way to say that I am connected to? Or y at - it a way to choose who to connect to?

    The taskbar is resizable, like a window, and it can be set to zero
    lines of ups. Maybe that's your problem, and fixing must be the
    first thing you should try. You may have accidentally resized to
    zero lines of ups. Place the cursor on the bottom of the screen and pass
    it upward and down slightly until it turns into a two-headed arrow.
    Click on, and then drag it to the desired size.

    If this does not work, it may be zero lines high on another facet of the
    the screen, try the above on all four sides.

    Finally, if none of those working, go to
