I am getting a MERLIN pop up repeatedly. I have tried to download a program called Registry Mechanic to fix the problem, but when I run it it finds a multitude or errors, but rather than repair them it tries to sell me a package to fix the errores. I read a post that says to use AVAST! or AVG as a free vius program, but another posting shows these as programs I should delete when havibg problems. I am really confused. What can I do to clean adware spyware malware etc and viruses that I already have and what should I install to keep from getting more. I am not very computer proficient and not sure this post will even work. I tried to reply to another post and it said I did not have proper clearence or something like that. This is my first attempt to use this forum.
