What operating system are you using?Microsoft Security Essentials (MSE)
is a free anti-malware solution for Windows 7 and Vista SP1/SP2 that combines the features of an anti-virus
and anti-malware scanner
to provide real-time protection against viruses, spyware, and other malicious software.Windows 8
and Windows 10
integrates a more robust version of Windows Defender
(and uses that name) for its anti-virus
and anti-malware protection
. Windows 8/10 Defender provides the same level of protection
against malware as Microsoft Security Essentials (MSE) provides on older operation systems and uses the same daily virus definition updates.
IMO Microsoft Security Essentials is just as good as any other free antivirus solution
(and probably easier to use for the novice) without bundled toolbars or nagging popups.
Although Microsoft Security Essentials provides some anti-malware protection...it does not provide comprehensive protection
and cannot prevent, detect and remove all threats at any given time. This is true for most anti-virus solutions. Anti-virus and anti-malware programs each perform different tasks
as it relates to computer security and threat detection. Essentially, they look for and remove different types of malicious threats.
In simplistic terms, Anti-virus programs
generally scan for infectious malware which includes viruses
generally tend to focus more on adware
, unwanted toolbars
, browser hijackers
, potentially unwanted programs
and potentially unsafe applications
. Anti-virus and Anti-malware solutions with anti-exploitation features
protect against zero-day malware
, drive-by downloads
and Exploit Kits
Therefore, you need both an anti-virus and an anti-malware solution for maximum protection
