May 25, 2021 4.0 Windows Defender is an application program that comes from Microsoft which is provided free of charge for users of the Windows OS system, which is found on every laptop and PC. Windows Defender is no less powerful than other antivirus such as avast, avg, smadav. Windows Defender on Windows 8 will always check for updates when we are online, so we don't have to be afraid of new and increasingly dangerous viruses. Pros Always active and gives a warning, Clean up to the maximum, Windows Defender will ask to restart if it finds a dangerous virus Cons Scanning using Windows Defender itself, there are two options, namely quick and full. This is where the weakness of Windows Defender is that sometimes the two methods are not too thorough so that small viruses can be bypassed. Device performance can decrease if you install other security applications besides this firewall application. Especially if the computer load is heavy and often performs many tasks though.

They have done an excellent job; but they still have a long way to go. People find it difficult to connect the dots holistically because of the way their documentation is structured. Microsoft Defender for Office 365 gets a nine out of ten from me. Pros It's a good extra layer of email security protection with some helpful features but it's not a one-size-fits-all email security solution. It includes near-instant detection and blocking of new and emerging threats, detecting and blocking potentially harmful applications that aren't necessarily malware. Cons The product's integration to operate across different operating systems needs to be improved, as well as better support for non-Microsoft file forms. Review Source AA Ali A.

Pros We use Microsoft Defender primarily as a spam-filter, and it performs that task very well. Cons Sometimes Microsoft Defender quarantines important, non-spam emails which causes us to not see them in time and miss certain communications or deadlines.

I will continue to use it both in my office and on my home devices. I trust it a lot as well as it is a Microsoft software product. Pros Very easy to use. I don't have to remember to do scans, because defender is on a schedule to run automatically. It quarantines anything I need to review on a case-by-case basis so I can make decisions on whether or not to remove potentially bad software. It keeps strong firewall up that I have control over as well. Cons Sometimes the scans can take a long time. Review Source Molly B.

Nutritionist Health, Wellness and Fitness Used the software for: 2+ years ### "Antivirus software" July 7, 2021 5.0 Generally Microsoft Defender is a basic antivirus that helps with minor issues. The fact that it is pre built in office 365 makes it easy to access and relatively cheap. Pros I like that is it pre built in Office 365 and that it is able to at least prevent common spams and viruses and is able to clean the device regularly protecting emails and documents. Cons I find the Microsoft defender for office 365 too basic and can therefore not prevent advanced issues. It also requires too many updates regularly which take long. Review Source AM Andrea M.

Pros Microsoft Defender for Office 365 is a great way to protect our online documents. I know for me, I am always stressed about my documents being hacked, but this program allows me to feel comfortable knowing my documents will be safe. Cons Always check with your company to see what you can and cannot store on a virtual drive, as they might not allow everything due to GDPR or HIPPA regulations. Review Source Tadeo R. Freelancer Computer Software Used the software for: 6-12 months ### "Great defender!" May 10, 2021 5.0 If we weigh the pros and cons of Windows Defender, in most cases, this antivirus is more than enough for normal use of the computer, but in the event that you are a regular at online shopping or are looking for greater protection for your company, it is better that you bet on a more powerful antivirus. Pros One of its main advantages is that it is a free program, unlike other options that we can find in the market, it does not have any paid version, so users can use all the options. Cons Although this antivirus has very good things, it should be noted that it is not perfect. In the event that you move through potentially dangerous pages or use P2P exchange programs, Windows Defender may be small and not offer all the protection offered by programs of companies that are exclusively dedicated to this purpose.

Tourism researcher Leisure, Travel & Tourism Used the software for: 6-12 months ### "Assured protection for everyday work" July 1, 2021 4.0 I don't have to worry much about virus when I'm working, it perfectly is in charge of that topic and I just can save my files, enter to web pages and send emails with security. Pros I have to highlight its email protection features. for For example, I use OneDrive everyday and I see that my files are safe, which is great since I save important information for my research and daily work. Also, it protects files from Microsoft Teams so I don’t have to worry when I use it with my partners. The protection for URLs within Word, Excel and PowerPoint are natively integrated and protection of mails don’t need additional configuration. Cons I think I'm ok with the features but I would suggest it could be integrated with Office 365, not a separate option. Review Source Similar Products Featured
