AVG Identity Protection™
Analyzes a software’s behavior in real-time to determine if it’s safe. This feature helps protect you against 0-day threats and malicious programs that could steal your passwords, bank account details, and other digital valuables.
AVG Identity Protection uses a technology called behavioral analysis to make sure all the programs running on your PC are operating the way they should. If it spots something suspicious that could indicate an attempted identity theft attack, it shuts that activity down, preventing any possible theft from happening. It doesn’t matter whether you’re running AVG software or security software from another vendor; identity protection runs alongside all popular programs to keep you safer when they’re online.
