Over the past couple of weeks, AVG has identified a virus that it is unable to remove. I have been getting the exact pop up from AVG saying that “Virus identified Win64/Patched.C” with “c:\Windows\System32\rpcss.dll”. This virus keeps coming up as an AVG security threat which cannot be removed. I have run Malwarebytes either but it was unable to remove it too. I searched on the web and it said the virus should be removed manually. Also I am getting pop ups and random ads on google chrome. Are these pop ups most likely being caused by this virus and if so, how do I get rid of it for good if AVG cannot actually delete them?
