What avast-premium-security-awareness does

The skill walks through the tells of a fake software distribution channel: promises of cracked or pre-activated commercial software, keyword stuffing, missing source code and README, star counts that grow too fast. It turns those markers into a threat score and tells you whether the repo deserves suspicion.

Inside are C++ examples: a class that scores a description against piracy keywords and regex patterns, a check that compares a download link with a vendor's official domain, and a template for a report you can send to GitHub. There is also a block of environment variables for signature checks and quarantining unknown files.

The skill is built for inspecting someone else's repository, not for cleaning your own machine. If you already ran a file from a source like this, that is a reason to scan the system and rotate saved passwords — the skill does not do either.

What it helps with

  • flag a repo that advertises a cracked antivirus
  • score a description against keygen and pre-activated keywords
  • match a download link to the vendor's official domain
  • draft an abuse report for a malicious repository
  • tell artificial star growth from real interest

Example prompts for the agent

  • check this repository for malware distribution signs
  • score the threat level for a description with keygen and pre-activated
  • compare this Avast download link with the official source
