A valid question from @omidomi .better protection=Kaspersky
better speed=Webroot
which one u need?
Actually I do too.
I went ahead with WSA plus it's on sale at Amazon for 9.99
Webroot = Signature depends on cloud mean it require active internet connection. In other word, as long you have active internet connection you will be on the latest Webroot protection, but if you don't have active internet connection Webroot will be dummy like Qihoo 360.
- Signature
Your main protection while disconnected from the internet is coming from SecureAnywhere's behavioral shields/detections and local heuristics.
There are a very limited amount of locally held definition signatures for certain critical items that don't require reaching the cloud. These are mainly for rare file infectors. Anything that is known as good from prior scans (while previously connected to the internet) will still be known as good if they have not changed when performing scans offline, which explains the speed of the scan.
Also, if a program or process was being monitored before going offline, it will continue to be monitored and these processes and their behavior will still be journaled. This journaling allows SecureAnywhere to keep an eye on possibly malicious programs or processes it was unsure about, and if they try to execute or end up being an actual threat, the damage done can be reverted.
Kaspersky have my vote here when it come to neat and nice user interface, while Webroot is not that good even horrible compare to Bitdefender 2016 user interface.
- User interface
Well we all knows that Webroot have less system impacts because all signature is store on the cloud on hard drive and RAM like Kaspersky does.
- System impacts
Hand down Kaspersky zero day protections. Webroot is decent enough but not as good as Bitdefender or Kaspersky. Also, Kaspersky have roll back feature which allows it to revert malware system changes.
- Zero day protections
Webroot has offline signature database, it is cached. it is true that webroot is less efficient while offline, but in those days who are offline...especially before a scan when the latest signature database must be downloaded.
UI doens't matter much
So does webroot. on HDD too.
Webroot was the first to do it...
Guys do some research before saying inaccurate facts.
Overall Kaspersky has stronger prevention modules than Webroot, but webroot many prevention features are still very good for a far lighter resources usage.
Note than Webroot is maybe a bit more expensive than Kasperky.
All depend what you look first. I'm a long time user of Webroot (since their first beta) and i never had any issues with it; not saying than webroot can be used a companion AV where Kaspersky can't.
UI is matter to me because i rather buy a product with nice and attractive user interface and less confusion than one with mediocre user interface, and easily get loss in the middle of the road.
I still consider Webroot lighter than Kaspersky because Webroot is cloud AV, but it does impact system a little bit when it scanning.
Webroot can be use as a companion antivirus, although i never try it and never recommend it since that is for paranoid people
not all companion antivirus are compatible because antivirus vendor keeps changing things a lot that can easily break their " compatible" easily.
For instance, Emsisoft Internet Security are not longer compatible with Malwarebytes Anti Malware at the moment because MBAM use a WFP driver to capture network traffic for their website blocking, and that driver could cause problems with the WFP driver used by Emsisoft Internet Security. EAM Compatibility with Malwarebytes Anti-Malware - Emsisoft Anti-Malware
really!? i am on a 3-4 year old machine , running half a dozen of security apps simultaneously and Webrot doesn't impact my system at all, even while scanning. Cpu barely goes above 20% and Ram usage is insignificant.
