Setup of a Computer

Free Programs for a Windows OS Computer


These are alternatives to Microsoft Defender Anti-Virus that are free.   

It's just an opinion and you may have other preferences.  I have used Avast and AVG and they are pretty decent especially for free software.   Microsoft Anti-Virus is very good at this point so I don't remove it or worry about it if somone has it and likes it.   

I don't care for Norton anymore and I especially dislike McAfee but if somone is using them and they like it it's acceptable.   I much prefer people use something they like and keep everything updated.      

Avast Anti-Virus

Good Anti-Virus. I have used this one.  
Updates frequently (several time a day at times) but doesn't interfere with your work.
Ability to scan all files before bootup is useful.  Now has an annoying tendency for pop-ups.

AVG Anti-Virus

Several friends use this and I concur - good anti-virus software. 


Avira Anti-Virus

Another one several friends use. It's good but I prefer others. HOWEVER, can be useful on older computers as it is lighter on resources.





I find the firewall in Windows to be quite acceptable for most situations.
There are good aftermarket ones you may wish to try.

ZoneAlarm Firewall

I used to use the ZoneLab firewall.  In time it was renamed.  It worked well when I used it but I haven't used ZoneAlarm.  I expect it is fine.  

Comodo Firewall

Used this too but it has been some time now.
