Quick decision
Need something free that actually works
You don't want to pay for antivirus. You need protection — or at least a cleanup tool — that actually does what it claims without hidden costs to your privacy.
Malwarebytes Free for on-demand cleanup. Windows Defender for background real-time protection if you're on Windows. Combine them for a functional free setup.
MalwarebytesFits for on-demand cleanup — run it when something feels wrong. Most trusted scanner for finding what other AV misses. Free version has no real-time blocking.
Go to Malwarebytes
BitdefenderMakes more sense if you want to invest in real protection — paid Bitdefender may cost less than the risk of an unmanaged infection over time.
