No problem, Vermon. In case you have any questions dont forget to post them in one of our topics

@verman. I try this method but after some time browser play same false things.... Any permanent solution.

@Tabeer it appears that you may have modified registries and possibly some other unwanted files on your comptuter. In order to find them, you need to scan your computer.

Here is more information how to do it:

Remove Malware From Your PC Completely

Bear in mind that the topic is for Windows 10 but it may also be relevant with Windows 8 and 8.1. For older versions of Windows simply press F8 while restarting your computer in order to get into Safe Mode.(I am referring to the first part of the instructions).

@never I never go to registry area. I also keep my laptop away from unwanted files as possible as i can, maybe some unwanted files create that keep my laptop busy. 

Tabeer I meant that your computer may have modified registry entires In It as a result of having an unwanted program on your computer.

Best Regards,
Never

Ok Never. got it. But things laptop done with me, irritate me.

@Tabeer - this might have to do with the "NewFolder.exe" malware we discussed, and sounds more and more like something tampering with registries and one you should remove.

I have replied to the topic where you asked for the malware. Try the things I have written and I hope that yields results.

With Regards,
Execute

@Execute, try every possible option which i know. Run a bunch of softwares, initially "new folder" removed but after sometime i don't from where "new folder" appear again.
