My PC is processing very slow and the reason for this is maybe the system is infected with viruses. I searched and got to know that my PC requires some authentic Antivirus software for fast processing and great security. However, as per my knowledge, Norton Antivirus is the top-most protecting application accessed by almost everyone to freely scan the PC and remove the threats if detected any. After knowing the fact regarding Norton antivirus, I have downloaded and installed it in my operating system to protect the device against viruses. But now the software is not running appropriately. So, want some fruitful solution from top-most tech-geeks to fix this issue. It is requested to the one who thinks they are capable enough to handle my problem and can easily sort it out within a few seconds or a minute.
