The fake update stopped before I saw it.
M., accountantI had already clicked 'install' on a video codec.
For anyone who has ever clicked 'update' too fast
Ransomware, fake tech support, and update pop-ups don't wait for you to notice them
Antivirus watches the install, the call, and the message before the story turns into a locked screen or a drained account.

Three scam stories your computer hears every day

What Antivirus does while the scam is still a story
Scans before the file wakes up
Behavior monitoring catches ransomware and trojans that signature scans miss, including files that arrive through a 'helpful' app. To find out which tools perform best in these detection tests, you can review our tested antivirus software options.
Blocks the fake support window
Pop-ups that claim your PC is infected, that your bank is blocked, or that a technician is ready to connect get removed before you answer. To evaluate how different security suites handle these intrusive browser hijackers and deceptive alerts, you can check our comprehensive antivirus feature breakdown.
Keeps updates real
It checks software updates against trusted sources, so a 'critical update' cannot become the thing that needs fixing. To see which security providers passed our update-verification benchmarks, you can explore our full list of evaluated antivirus programs.

How the protection runs
- 1
Scan the device
A quick scan looks for ransomware, trojans, fake support tools, and unsigned installers.
- 2
Block the story
Suspicious messages, pop-ups, and remote-access attempts are stopped before they become a task.
- 3
Repair the damage
If something slipped through, TotalAV helps remove it and restore the files it touched.
A conversation with Antivirus
- You
I keep getting fake update pop-ups on my PC.
- Antivirus
I can check the update source and block unsigned installers.
- You
What if a tech support pop-up asks me to call or allow remote access?
- Antivirus
I flag fake support windows and block the remote tools that follow.
A simplified conversation, not a real call.
The same device, two endings
Without protection
A fake update installs a trojan. A tech support pop-up appears. Files get encrypted. The story ends with a ransom note.
With protection
The update is checked, the pop-up is blocked, and the file is quarantined before it can lock anything.
What a scam looks like on your device
- Avoid: A pop-up that says your PC is infected and demands a call.
- Avoid: A 'recovery' email that sets a deadline and links to a login page.
- Avoid: A software update that arrives from a domain you do not recognize.
- Do: A signed installer from the vendor's own site.
- Do: A support page that asks you to verify through your existing account.
- Do: An antivirus that blocks the behavior, not just the file name.
Common questions
Does Antivirus replace my current antivirus?
It can run alongside, but if you already have a full antivirus, use antivirus for the extra layer: pop-up blocking, update checking, and behavior monitoring.
Can it stop a ransomware attack that is already running?
It can quarantine active threats and help restore files, but the best protection is before the file runs. Keep backups separate.
Will it slow down my computer?
A quick scan is light. Full scans can be scheduled for when you are not working.
What happens after the first month?
Nothing automatic. There is no card on file, so it stops unless you decide to continue.
