Slow - very slow - too slow - for about a decade now - 12,000 forum results concur

I’ve used Webroot for almost a decade. It absolutely the strongest protection out there. I have never, ever, not even once, had a virus infection that I had to remove. It always blocks it. I love Webroot… except….

The bad news… it DOES cause Windows slow down a LOT. This has plagued Webroot for years… really ever since I initially recommended it to a former employer and convinced them to switch to it back in 2013. They now have it deployed to several thousand endpoints.

I would really like Webroot to focus on improving the speed. There are unnecessary things that occur in the WR client, such as when there is a directory exclusion set in the console, the WR client re-scans the entire directory every so often, finds all EXEs, and re-determines its status even if the directory is excluded. Many processes are tracked, whether excluded or not, and it still runs through its system, it just doesn’t alert on the issue. This is just one example of unnecessary processing power.

Sadly I am reminded of how fast my computer really is when I remove Webroot for one reason or another. This time I’m removing it to diagnose a compatibility issue.

With all that being said, I have not stopped using Webroot, but only because of its ability to truly block infections.

The speed issue is a night and day difference though when WR is removed from a computer. Seriously… that’s the ONLY thing that changes…. and the computer flies.

I’ve been considering switching my company away from Webroot for this very problem. There are many other great endpoint products that users do not report the sluggish issues. I hate to recommend to my MSP clients to use another product, but there’s really no other option when the speed improves 20-40% when Webroot is removed, even with Windows Defender enabled.

I’ve worked with WR support for years, opened many tickets, and unfortunately that’s the response many employees give. It’s a proper one from a support standpoint, but the issue is not with the computers that WR is on - it’s not the operating systems - it’s not the third party software - it’s not the network - it’s with the code itself. This isn’t just a bug at this point, it’s a business issue that I foresee causing WR as a company, financial loss, as more people switch away due to the sluggishness. I am not sure if management is not aware of this issue, if the development team is unaware, or if it’s a topic that is purposely not discussed for some reason or another. I really like Webroot, I want to stay on your team as a client, but it’s … no bueno and hasn’t improved. :-/

The issue has persisted from Windows 7, 8, 8.1, 10, and now 11.

I have taken advantage of the exclusions heavily… extremely heavily. Nearly a third of the apps that we use on a day to day basis are blocked. Nothing fancy either - Photoshop, ISO files, Acronis backup files, various tools. The exclusions do help, but only about 15% with speed.

I love it otherwise. :-/

I’m sorry you are having specific issues with slowness on your computer. How have you confirmed with support that it is Webroot that is causing this issue? We have literally been the fastest security solution for years based on 3rd party testing. We are industry known for being the security software that DOESN’T slow down your computer and have proven results on this claim. See the Passmark testing results which specifically test the performance of a computer during a number of tests including: memory, CPU, network throughput, file copy/write, file de/compression, app launch, browser speed, etc - all tested during installation, during scan, during idle. 

^these are the most recent, but we’ve also held this title for almost a decade

I am by no means doubting your claim that your computer had seen an impact and that your experience has you concluding it’s Webroot, but I believe there is a reason for this. I’m sure logs could be analyzed to pinpoint the issue as I’ve only seen slowdown if Webroot encounters a process that has not been whitelisted and it is monitoring it at certain levels. I don’t see any support tickets with the email you have used here, but if you want to DM me the email you did use for support, I could look into this for you. 


You can also submit a ticket from the computer in question with a description of your issue and logs would automatically be uploaded and we can take a fresh look at this

I have our MSP deployed the Webroot agent to over 10K endpoints with no major complaints of slowness due to the agent being installed itself. 

Based on what you mention with regards to using exclusions all the time, I think that itself is your main reason (also could be due to policy settings), that’s causing your problems.

You shouldn't need exclusions for the common software like Acronis, Photoshop etc. unless you have Photoshop extensions. 

Setting A LOT of exclusions WILL slow your agent down as it has to keep referencing the exclusions each time it goes through a regular scan or you use the software that the exclusion is set for. 

It’s best to NOT use exclusions at all but instead contact support to have the files/programs whitelisted so that the agent itself already knows it is safe to use. 

We try and avoid exclusions and in over 10K endpoints, might have only a few clients with a couple of extensions. 

I’d go that route first and get rid of all your exclusions and actually whitelist the programs.

Hope this helps
