So first my C drive was named as label I remember that I did not changed this.Next I got these weird files also in the C drive like in the C drive not in a folder in C, those were 25caed58e9e1c2c4f9259b9fec4c(empty folder),32A809DCD6BD(file),bootsqm.dat(DAT file),msdia80.dll(application extension). These files are really weird, I hope someone answers. I'm thinking this is a cause of a virus because I have a lot of apps installed in my laptop, but theese things appeared before I installed a lot of apps here. Again I hope someone answers and get y laptop fix.
Ps: I am advanced on using computers so if you some geeky things to do for me to fix my laptop I could do it. Thanks

Please download MiniToolBox  , save it to your desktop and run it.
Checkmark the following checkboxes:
  List last 10 Event Viewer log
  List Installed Programs
  List Users, Partitions and Memory size.
Click Go and paste the content into your next post.
Also...please Publish a Snapshot using Speccy taking care to post the link of the snapshot in your next post.

   Go to Piriform's website, and download the free version on the left.  Click Download from Piriform.com (the FileHippo link requires an extra click). Or if you want to use a portable version of Speccy (which doesn't require installation), click the builds page link and download the portable version. You will now be asked where you want to save the file. The best place to put it is the Desktop, as it will be easy to find later.

    After the file finishes downloading, you are ready to run Speccy. If you downloaded the installer, simply double-click on it and follow the prompts until installation is complete. If you downloaded the portable version, you will need to unzip it before use. Right-click the ZIP file and click Extract all. Click Next. Open up the extracted folder and double-click on Speccy.
     Once inside Speccy, it will look similar to this (with your computer's specifications, of course):

     Now, at the top, click File > Publish Snapshot.

     Click Yes > then Copy to Clipboard

Now, once you are back in the forum topic you are posting in, click the ADD REPLY or REPLY TO THIS TOPIC button. Right-click in the empty space of the Reply box and click Paste. Then, click Add Reply below the Reply box.

The issues of those weird folder names has been around since the XP days so here is some copy/paste about that:
When some programs (including Microsoft programs) install things, it may create a temporary folder consisting of 20-30 random letters and numbers or random 
numbers and letters in the root drive of the volume with the most free space.
This explains why sometimes the folders are on your C drive or on some might be on another drive - which one has the most free space?
For example you may see a folder on your C or D (or other) volume similar to:
There may be other folders and files under that main temporary folder such as amd64 and i386.
These should normally be removed when the installation is complete, but sometimes they are not - especially if the installation fails.  They are harmless but annoying.  
You may think something is wrong when there is not or be afraid the files are really needed.  To avoid confusion you can delete the temporary folders.
If your installation failed or the installation does not delete the randomly named folder when it completes running and you run the installation again, the installation again will make another randomly named folder.  
Sometimes you will see several folders like this and they can all be deleted.
You may be able to identify the installation (for curiosity) by looking at some of the folder contents and decide if that installation was okay, just delete the files/folders.  If the installation did not work 
properly for some reason, running the installation again will just create a new randomly named temporary folder so the old temporary folder is really of no use.
Sometimes the folders are stubborn to delete.  Even if you are an Administrator on the system you may get a "sharing violation", "access denied", "being used" or similar type message when trying to remove the 
temporary folders.  Installations sometimes use different permissions than a regular user with Administrator group might have.
There are many methods to try to remove the folders and some involve third party programs to install or changing certain Windows settings that may compromise your system security if you don't change them back 
when you are done.
Booting your system in Safe Mode (pressing the F8 key repeatedly right before XP tries to load) is a good first method to try and remove the folders since it doesn't involve making any changes to 
your system configuration or downloading any third party programs.
For Windows 7 you might need to "take ownership" of the offending files/folders and then delete them and this link tells you how to do that:
If none of the above work a popular third party tool called "Unlocker" is helpful.
Unlocker can be downloaded from here:
You may need to use Internet Explorer to get Unlocker to download properly.
Do not be tempted to download any other software that promises some miracle on your system.  Just download the correct Unlocker for your system (either 32 bit or 64 bit).
Pay attention when installing Unlocker since it wants to add a bunch of options, addons, shortcuts, and other extras you don't need, for example:
UNcheck the box to install the Babylon Toolbar and click Next
UNcheck the box to Check for Unlocker updates
UNcheck the box to install the Unlocker Assistant
DO check the box to install the Explorer Shell extension (you are going to need that)
Click Install, you do not need to reboot.
The reason you need to add the Explorer Shell Extension is so when you right click on the offending folder, you will have an Unlocker option to choose.    
Explorer Shell Extensions help make up the right click menu when you look at a file or folder.
Right click one of the offending folders and choose Unlocker, then choose the Action (that would be delete) and click OK and you should see a Success 
message and the folder should be gone.
I would just install Unlocker long enough to clean up those leftovers and then, I then generally use Add/Remove Programs to uninstall Unlocker and all parts of it.  You can always 
install it again some other day if you need to.
Unlocker can be uninstalled when you are finished using it.
Reboot when you are finished to be sure the annoying folders are really gone.
Have you considered performing a Google search on the other files where you might see results like this:
