Webroot
Also called webroot secureanywhere, wrsa, webroot antivirus
A small-footprint cloud antivirus often bundled by ISPs. The process is WRSA.exe. It is not Windows Security.
What you need to know
WRSA.exe is Webroot's small cloud agent. It should take Defender's slot.
Webroot is an ISP-familiar cloud AV now under OpenText. The agent is WRSA.exe. A tiny folder is expected. Two live engines with Windows Security is the conflict.
- What is it?
- Small cloud AV often bundled by ISPs
- Why is the folder tiny?
- Definitions are in the cloud
- Plus Defender?
- No. One live engine
What is Webroot?
Webroot is a small-footprint cloud antivirus. WRSA.exe is the Windows agent. ISP bundles are common. OpenText is the current owner.
If you have never used it
If an ISP mailed a Webroot key, this is that small cloud AV, not Defender. Download it from webroot.com. WRSA.exe is the agent. OpenText owns Webroot. The agent should take the antivirus slot. WRSA.exe plus live MsMpEng.exe is the two-engine fight. The tiny disk footprint is the pitch, not a missing install.
What is it used for?
The agent is small on disk because definitions live in the cloud. It should still own realtime so Defender goes passive.
A cable-company letter is a common source. That key is Webroot, not Norton just because both arrived in the mail.
Thicker Webroot plans add extras. WRSA.exe is still the agent.
Who is it for?
- People who activated an ISP antivirus key
- Users surprised that Program Files\Webroot is tiny
- Anyone with WRSA.exe next to live Defender
Current status
Actively sold under OpenText. This article is consumer Webroot on Windows.
How old is it?
Webroot dates to the 1990s and became a cloud-signature AV. Carbonite and then OpenText owned it. Current consumer branding is SecureAnywhere. A 2004 Webroot Spy Sweeper box is a different era.

Common problems
WRSA.exe plus live Defender
Webroot should own realtime. If MsMpEng.exe still scans, both engines are live.
Offline PC looks unprotected
Cloud look-ups need a network. That is the product model, not proof the files were deleted.
Getting unstuck
Install from webroot.com with the ISP key
A "Webroot 2026 full" host is not OpenText.
Check Windows Security for Webroot
The owner should change after a successful register.
Do not add Norton just because a second mailer arrived
Two resident suites is the fight. Pick Webroot or Defender or the other paid product, not all three.
Alternatives
Windows Security if you drop the ISP suite. Norton or McAfee if that is the other mailer, not a stack.
