Anti-Virus Software Not Working on Windows 8.1 Preview

Recommended Posts

Even though Symantec has already announced that its security products are fully compatible with Windows 8.1, it turns out that most anti-virus apps on the market do not work on the first Windows 8 update.

Several users have confirmed on Microsoft's support forums that anti-virus software doesn't launch on Windows 8.1, including apps such as Norton 360, Avast Anti-Virus, and Micro Titanium Maximum Security Suite.

At this point, the built-in Windows Defender seems to be the only choice for users who wish to give Windows 8.1 Preview a try. Windows Defender is pre-installed on all Windows 8.1 machines and given that it's included in the operating system, the CPU and memory footprint should be minimal.

Security companies are most likely working to make their apps compatible with Windows 8.1 Preview as we speak, so expect a new wave of announcements on this particular topic anytime soon.

What Microsoft labels as a Preview - in real world use, is generally a beta . . . . . . . . . . historically speaking.

By the time the 8.1 goes RTM, most software Developers (and drivers) would be compatible - that's the basic idea of a Preview (going public.)

No 3rd party antivirus software would work yet with preview version of windows 8.1 I think thats why Microsoft has built-in windows defender to this release

OR BOTH in some cases... LOL!

But regardless... this news is fairly bad no matter how its looked at! At least AV Vendors will have more time and all to hopefully make them compatible with Windows 8.1 for when it launches or sooner :D

It should not come as a Surprises .. Some call it " Public Preview " but me thinks its just Beta .... Generally, beta version are known to contain few bugs which are supposed to be fixed in the Final Verson ... So Download and Install with care .... Cheers guys ... :) :)

@7h3Pr3d47oR,

As MS is now going for a rapid release cycle, this is something which will happen every year. Bearing in mind this is not rtm they have time to fix bugs etc and have their products ready.

I can confirm that Kaspersky AV 2013 does not work.

Kaspersky failed to allow windows 8 apps to work either when it first came out despite being "Windows 8 ready"

The original poster of this tweak on comodo forums, also mentioned that this tweak in theory should work for Kaspersky if anyone wishes to try

The reason

The firewall driver was failing to initialize because the driver wasn't getting installed under network adapter due to limits imposed by Microsoft on number of network filters that can be installed on windows 8.1. The default value on a every stable Windows OS is 8 but for some odd reason they changed it to 1 maybe because this is a beta version, not sure though.

.The fix

Run regedit, go to this value
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network
On the right side you will see MaxNumFilters REG_DWORD change it's value from 1 to 8. Reboot your machine and then install CIS, everything works just fine thereafter.

If you don't have the above DWORD, you can simple create a new one by right click selecting New \ DWORD name it MaxNumFilters and change it's value to 8.

This has been a known issue with Preview releases of Windows 7, Vista and XP, too (possibly with Windows 98 and Windows 95, as well - can't remember before XP era.) ;)
