Free Trojan scanner

Scan and remove Trojan horse malware from your device, or get proactive protection with Malwarebytes Premium.

Trojan horse virus symptoms
Trojans disguise themselves as legitimate software, so they can be hard to spot. Watch for these warning signs.
Lots of desktop pop-ups
Frequent pop-up ads and messages advertise products or say your device is infected.
Slow computer
Trojans and the malicious software they download take a lot of computer resources, which makes your device run slowly.
Applications won’t run
Programs won’t run from the Start menu or Desktop—or programs execute that you didn’t start.
Annoying Internet pop-ups
You get multiple pop-ups the moment you start browsing the Internet.
Your computer has a mind of its own
Your device turns off, launches applications you didn’t start, or prints documents you never sent to the printer.
