Avast One review

Avast One is the easiest way for a student to put free protection on both a laptop and a phone, since Avast offers free versions for PC, Mac, Android and iPhone or iPad. Avast says the free tier includes its malware and ransomware protection, Web Guard for phishing sites and Avast Assistant, an AI helper that tells you whether a message or offer could be a scam. Ransomware Shield stops untrusted apps from changing, deleting or encrypting chosen files, which is useful for coursework folders. If you want more, Premium Security inside the Avast One app adds Email Guard, which blocks suspicious emails rather than only links and attachments. The 1 PC plus 1 mobile plan costs $49.08 for the first year, the lowest paid price we found here, but it renews at $77.99. A 10-device plan costs $69.48 for the first year. The free app suggests paid upgrades, so expect prompts.
