@Tabeer - this sounds related to your other problem with the "Newfolder.exe" malware.

What is your operating system? It looks you have some leftover files from the malware in the registries.
You need to either check the registries or find a program like a registry cleaner or an anti-malware tool,
that also cleans the registries and looks for trojans and rootkits. Try Avast or Malwarebytes Anti-Malware for example.

Make a quick scan with either of them, and write back with the results.
