What's New

* Spyware Doctor with AntiVirus - Spyware Doctor customers can now get a free optional upgrade to get our powerful AV engine fully integrated into Spyware Doctor. You don't need to pay any extra to get full comprehensive anti-malware protection, plus AV works with all our scanners and guards. So if you receive an email it's checked for both Spyware and Viruses, or if you do an Intelli-scan we check for both as well. (We made it optional as we know some people only want SD for its award-winning anti-spyware protection and want to mix and match it with other security solutions.)
* Incremental updates and a new database format - this means you will have smaller database definition downloads, faster program loading and on-the-fly database updates. We also have optional automatic silent updates that require no user intervention, and most updates can happen live without a restart of Spyware Doctor or the operating system.
* Intelli-scan - anti-virus and anti-spyware scans are taking so long these days that some people just won't run full scan anymore. That's why we came up with Intelli-scan, it is designed to detect active spyware, using our patent-pending spider-scan approach, in a matter of minutes. You can still run a full scan to detect those inactive and hard to find threats, but for everyday use Intelli-scan is fast and effective.
* Lower resource usage and faster start time - pretty self explanatory!
* New and Updates Guards - now included Email Guard to scan incoming and outgoing emails, File Guard to scan files in real-time as they are used. Updated Guards include Process Guard to detect more types of rootkit attacks, Site Guard being expanded to support all browsers, Browser Guard to support Firefox and Internet Explorer, and all the others updated to take advantage of our new even lower-level system integration.
* Vista™ Support - Spyware Doctor v5.0 works on Vista.
* Improved mutli-user support - Spyware Doctor v5.0 supports the removal and detection of threats from all logged in user accounts. Scans can be performed at once without the user having to login to each account.
* Self-protection - Spyware Doctor protects itself better from being compromised by malware.
* Full global white/black list support - consistent support across all scanners and guards.
* Lot's of other things - scan external drivers such as USB sticks, ability to pause scan plus lot's more.
