While some types of free software are OK (example, VLC Media Player), it's best to stick with a paid AV/AM solution. I use a ESET Smart Security on some, Emsisoft Internet Security on others, and most has Malwarebytes Premium Lifetime licenses, where I stocked up when on promo as a second layer of protection.i know Avast is ok . but i like free software
Works good if one has Malwarebytes Premium to intercept what it doesn't. Have had Windows Defender (Windows 8 version onwards) on several systems since 2012, and hasn't caught a cold, let alone a virus.Just use Microsoft Security Essentials or Windows Defender and you will be safe. I use it and it works. Try it, it's FREE
You may want to download & run a free scan with Malwarebytes, now at version 3, which will offer a 14 day free trial to Premium features, no harm in accepting. MBAM has now evolved into a full fledged AIO AV + AM app, if running the licensed versions, of which on Newegg, one can find 3 PC's for the price of 1 deals, usually download only. For $24.99 it can't be beat, and is in my arsenal of security apps.In Windows 10, I use Defender, made by Windows for Windows. I added Sandboxie as well, and still use WinPatrol.
I added Kaspersky, Acronis, Malwarebytes Anti-malware, and Ccleaner to round things out. Malwarebyte's pay version works fine with Defender and Kaspersky, which is the only antivirus that catches everything in unbiased testing, tested it myself, it found two Trojans that Norton and Defender both missed. Was glad to pay for two years at that point. Evidence trumps drama.In Windows 10, I use Defender, made by Windows for Windows. I added Sandboxie as well, and still use WinPatrol.
So does Webroot have to be connected to the internet to work?Webroot works differently. If you want to take it literally yes Webroot doesn't flat out block everything 100% it flags items and runs it through their cloud. While that is happening everything is journaled and rolled back to a clean state if it's determined to be malicious Webroot will even rollback ransomware and encrypted files.
