Ransomware protection and recovery limits

Reduce opportunities for an attack

Keep your operating system, browser and document software updated. Use a standard account for daily work. Do not enable document macros or run an unexpected installer because a message asks you to. Restrict remote access and protect administrator accounts with strong authentication.

Understand the rollback boundary

PremiumAV describes a bounded rollback vault for previously backed-up documents. Recovery depends on valid earlier copies, configured coverage, available storage and a working recovery path. It cannot recreate files that were never backed up. Keep a separate backup that ordinary PC accounts cannot overwrite.

Test restoration before an incident

Choose harmless sample documents and verify that restored copies open correctly. Record covered folders and retention limits. Business teams should identify who approves restoration and how to preserve evidence. Do not test with real ransomware on a working computer.

Respond to unexpected encryption

Disconnect the affected PC from networks and backup drives. Avoid changing encrypted originals. Contact IT or support and record the time, alert text and affected folders. Use a separate trusted device for account recovery if compromise is suspected.

Check the exact scope

Ask which recovery paths have been qualified for your setup. A feature name does not prove broad efficacy or recovery guarantees. Continue making protected backups even with antivirus installed. Compare Home and Enterprise requirements before choosing a licence.

Questions and answers

Can antivirus recover every encrypted file?

No. Recovery requires usable earlier backups or another supported recovery method. Files outside backup coverage may be unrecoverable.

Does rollback replace a separate backup?

No. A local rollback vault has bounded coverage and retention. Keep a separate protected backup and test restoration.
