Hey!
 
I've been recently experiencing this issue on my machine. On occasion, defender turns of mysteriously. This was after I uninstalled BitDefender. Should I be concerned. Are there viable alternative antivirus software that you recommend?

Since Windows 8/10 Defender includes anti-virus protection, it typically is disabled by the installation of a third-party anti-virus program. If a trial anti-virus (i.e. McAfee, Norton, etc) came preinstalled on your computer or you installed one, it most likely turned Windows 8 Defender off (disabled) to avoid conflicts. Windows 8/10 Defender will remain disabled until that anti-virus software has been completely uninstalled. In some cases, you may need to download and run the anti-virus vendor's clean up tool to remove any remaining remnants. If not, Defender may not work properly.

What about Open Source protection programs. Are they any better?

ClamWin Free Anti-virus is useful if you want something portable on a USB or removable drive, however, it does not include an on-access real-time scanner to automatically scan your computer or scan files as you download them. That means you have to schedule a scan of your system or manually click on a file to scan it individually in order to detect any malware. ClamAV for Windows is a cloud-based anti-virus software similar to Panda except it is open source.

In simple terms, Cloud computer refers to having programs and data reside on an outside network device instead of permanently on your local hard drive. In theory it turns your browser into a flexible smart terminal and the main program you execute. The program you run and data you store is somewhere else on the planet similar to the old concept of a main frame.

What on Earth is “Cloud” ComputingPanda Security was founded in 1990 and the company was one of the early pioneers in anti-virus software. They are among the top 5 largest vendors and in 2009 were the first IT security company to introduce cloud-based antivirus with its Collective Intelligence technology. With Panda Cloud Anti-virus you do not need to be connected to the Internet all the time in order to be protected. Panda stores a local cache copy of "Collective Intelligence" for offline operation. If you are disconnected from the net, it still works in the background, checking files against its local cache of the most common threats in circulation. I do not know if ClamAV for Windows provides this same type of protection.

I never used Nixory.

Many site rating vendors (i.e. McAfee SiteAdvisor, WOT, Google's Safe Browsing, Webutation, avast! WebRep, etc) use a system of volunteer testers that continually patrol the Internet to browse sites, download files, and submit information. All the results are documented and supplemented with feedback from users, Web site owners, and analysis from their own employees. The advising site vendor then summarizes the results typically into into a color-coded red, yellow and green ratings scale to help inform Web users as to the safety of each tested site. While these tools are useful, they are not foolproof and sometimes may provide misleading ratings. Just because you visit a risky site, that does not automatically mean the site is bad or that your system has been infected by going there. In contrast, going to a safe site could even prompt a warning. There are legitimate programs which are falsely detected by various anti-virus programs from time to time. This sometimes results in an inaccurate site rating/warning of potentially dangerous software when that is not the case. Thus, the use of such rating sites does not always guarantee an accurate rating of the results they provide. Further, for the novice user, rating sites can provide a a false sense of security.

IMO Windows built-in Firewall is enough.

In terms of other security software, I also have HerdProtect and Malwarebytes on my system. Is this enough or are there any other tools you recommend for me to have on my system?
