I have Windows Defender Beta. Should I remove it and install the non-beta version.

Best wishes. whatapalaver.

Actually, just install the final version over the beta (the beta expires this month as I recall). I've done it on 2 systems so far without any problems.

Thank you Sir.

That's great - except for the fact that a horrible little programme called Ultimate Defender (and possibly others) is currently popping up Adult Contact ads on my work desktop every five minutes, while my newly installed and updated Windows Defender twiddles its thumbs and says (I quote):

"No unwanted or harmful software detected.
Your computer is running normally."

I had to close pop-up windows twice while copying that message...

If you receive a Windows Defender error message: "0x80071b90 the systems license has expired"
Windows Defender Beta 2 v1.1.1592.0 expired 12/31/06...If you have version 1.1.1592.0, you must first manually uninstall Windows Defender before you can install version 1.1.1593...Microsoft Windows Defender is no longer installable or supported for Windows 2000.

Update to version 1.1.1593 is available for download here.

Is this windows defender any good or should i just stick to AVG anti - spyware?

Defender targets general spyware/adware while running in real-time. AVG AS is very effective against many types of Trojans and malware but to take advantage of its real-time protection you must purchase it after the trial period. No single product is 100% foolproof and can detect and remove all threats at any given time. The security community is in a constant state of change as new malware infections appear. Each vendor has its own definition of what constitutes spyware and scanning your computer using different criteria will yield different results. The fact that each program has its own definition files means that some malware may be picked up by one that could be missed by another. Thus, a layered defense using several products (including an effective firewall) to supplement your anti-virus provides the most complete protection.

ok thanks, but you haven't really answered my question, would you recommended using windows defender?

thanks

Its not the best but then again its free. And if your not using anything else, its better to use it than not to.
