Internet shows as connected. Works for a bit, then stop working, but still connected

[Gathe3]

Hello.

 

My problem is the following:

I have an internet connection of 10 mb. It always shows as connected in my Dell Notebook, but sometimes it doesn't work, even though it says it's connected and without any errors.

For around 15 minutes my internet works fine. But after 15 minutes, it stops working (it still says it's connected and without any errors!). Sites don't load, Skype doesn't work, internet in a whole stops working for a while (around 15 minutes as well). I'm using Google Chrome, and whenever sites don't load because of this stupid problem I get an error from it. Most of the time, the error is dns_probe something. The point is: nobody did anything to my router/internet connection for it to be like mentioned above. So, I started to think that it may be a virus or a malware that's causing it. I ran Avast, McAfee, MalwareBytes and CCleaner, and nothing changed. Then I opened the programs list thing that Windows have and started searching for programs I don't know. The only program I found was 'The Desktop Weather 1.2' by ShenZhen Enode Technology co,.Ltd. Then, I uninstalled it. I'm pretty sure that whenever you uninstall a program, mainly malwares or virus, they don't get completely extinct from your PC. It didn't change a single thing. Should I post a log here so that you can see if there's anything wrong with my PC? If so, how do I get one? Please help!

 

Additional notes: sometimes a random cmd opens and closes almost instantly in my PC. I saw that the cmd has the name of a file, but it's so fast that I can't see what the file is;
                           I'm using a Windows 8.1;

                           my router is a Belkin Surf N300.

Hello,
    
 
They call me TwinHeadedEagle around here, and I'll try to help your with your issue.
 
     
    
Before we start please read and note the following:

• We're primarily oriented on malware removal here, so you must know that some issues just cannot be solved and you must be prepared for this. Some tools we use here will remove your browser search history, so backup your important links and all the files whose loss is unacceptable.
• Limit your internet access to posting here, some infections just wait to steal typed-in passwords.
• Please be patient. I know it is frustrating when your PC isn't working properly, but malware removal takes time. Keep in mind that private life gets in the way too. Note that we may live in totally different time zones, what may cause some delays between answers.
• Don't run any scripts or tools on your own, unsupervised usage may cause more harm than good.
• Do not paste the logs in your posts, attachments make my work easier. There is a More reply options button, that gives you Upload Files option below which you can use to attach your reports. Always attach reports from all tools.
• Always execute my instructions in given order. If for some reason you cannot completely follow one instruction, inform me about that.
• Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay someone to repair it.
• If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.

I can't foresee everything, so if anything not covered in my instructions happens, please stop and inform me!
There are no silly questions. Never be afraid to ask if in doubt!
