I would uninstall Norton before it expires (to avoid any issues that sometimes occur after expiration) and just use Windows 10 Defender
(Windows Defender Antivirus
) which is Microsoft's free built-in (integrated) anti-virus
solution. It provides the same level of protection
against malware as Microsoft Security Essentials (MSE) provides on older operation systems plus enhanced protection against rootkits and bootkits
and protection against potentially unwanted programs
if that feature is enabled. Microsoft has incorporated a number of significant improvements
which make it competitive with other major anti-virus vendors including many paid for products.
Windows Defender Exploit Guard
has four components of new intrusion prevention capabilities
designed to lock down a system against various attack vectors and block behaviors commonly used in ransomware attacks before any damage can be done. "Controlled Folder Access" Anti-Ransomware
is a feature that allows you to protect files in certain folders to that they cannot be modified by unknown applications. This protects the files within these folders from being encrypted by a ransomware infection. In Windows 10 Spring Creators Update
, Microsoft also added a dedicated Ransomware Protection section
in the Windows Defender Security Center under the "Virus & threat protection" settings.
