Three layers of live defense that stop ransomware before it can encrypt your files.
Ransomware is malicious software that locks up your personal files (photos, documents, tax returns) and demands payment to unlock them. By the time most antivirus programs notice, the damage is already done. TuneBit's Ransomware Shield runs in the background and uses three independent techniques to catch ransomware while it is happening, then kills the attacking program before much harm is done.
Leave it enabled all the time. Protection is only effective while active.
SRP is a built-in Windows feature that blocks programs from running in folders where legitimate software rarely lives — places like your Temp folder, %AppData%, and the Recycle Bin. Ransomware almost always launches from one of these spots, so SRP stops the attack at the starting line.
Good to know: A handful of legitimate installers and updaters also run from these folders. If you see an app refuse to launch after enabling SRP, use the Manage Whitelist button to add it to the allowed list.
TuneBit plants tiny decoy files with tempting names (like !_passwords.docx) in folders ransomware loves to attack: Documents, Desktop, Pictures, and so on. If anything tries to modify or encrypt a decoy, TuneBit knows something is wrong and reacts in milliseconds.
You won't normally see these files — they're hidden. Don't delete them; they're your silent alarm.
This watches your personal folders for the tell-tale pattern of a ransomware attack: rapid, mass file renames or a sudden burst of files being rewritten. When that pattern appears, TuneBit treats the offending program as hostile.
