Honest about antivirus, and one window only

A release that makes the security check honest when another antivirus is in charge or a reading cannot be confirmed, keeps the app to a single window and a single tray icon, and explains a refused batch of repairs in one plain sentence.

• When another antivirus is your active protection and Windows Defender runs alongside it in passive mode, the security check says so instead of reporting virus definitions as thousands of days old. When the age of the definitions cannot be read, the app says it could not confirm the age rather than calling them current or outdated, and a repair plan built from an earlier reading can no longer show an impossible age.
• A scan with only informational findings now says when nothing needs a fix, without suggesting another full scan, and the closing message says if a reading could not be confirmed. When Defender is your active antivirus and its platform is behind, you get the update note even when the definition age is unreadable.
• Opening the app while it is already running near the clock brings the existing window forward instead of starting a second copy with a second tray icon. Cancelling the administrator prompt no longer lets later launches start duplicate copies, and opening the app brings an existing administrator window forward.
• When Windows refuses to start a batch of repairs, the app gives one plain explanation instead of repeating a raw Windows error for each repair, and keeps those repairs available to try again.
• The anonymous usage service now removes recognized user and computer names from diagnostic text before storage, records whether the app ran as administrator, and filters repeated launch reports.
