Although it's based on Grisoft's own paid-for AVG 7.0, this free version doesn't offer quite the same feature set. You may not get technical support, access to the fastest update servers or scheduling abilities, but given its price - or lack thereof - it's still a reasonable basic antivirus package.
Regular, downloadable updates to virus definitions ensure you're protected against the latest threats, and incoming e-mail is checked too.
There's a Resident Shield for real-time protection as you open and run files, as well as an automatic scan on boot-up and a Virus Vault to quarantine any bugs that are found. Ursula Seymour
