Short answer
TeamViewer can help a trusted technician support you, but never install it or share a code because of an unsolicited call, popup, or refund story.
What TeamViewer does
TeamViewer lets a remote person view or control a computer with your permission. The name may be legitimate while the person using it is not. The safest question is how the session started.
If someone already connected
- 1
End the connection
Close TeamViewer and disconnect the computer from the internet if the person is still active.
- 2
Use a trusted device
Change email, banking, and other important passwords from a different device. Contact your bank through a number you already trust if money was involved.
- 3
Check access
Remove unattended access and note any programs or settings changed during the session.
- 4
Get the computer checked
A cleanup should verify what happened rather than simply uninstalling one program. See remote-access scam steps.
What not to do
- Do not call a number shown in a virus warning.
- Do not share a TeamViewer ID or password with an unsolicited caller.
- Do not assume deleting the icon proves the session caused no harm.
Common questions
- Is TeamViewer malware?
- TeamViewer is legitimate software. A scammer can misuse legitimate remote-access software, which is why the caller and circumstances matter.
- Can a technician use TeamViewer safely?
- Yes, when you start the session with a technician you trust, stay present, and end access when the work is complete.
