There appears to be a growing trend for Anti-virus manufacturers to abandon support for older versions of operating systems, and Vista appears to be the one catching the brunt of it.In April this year we started getting a rash of reports that the new version of Avast! was giving problems. that seemed to die down in about June/JulyIn the past couple couple of weeks, we have been seeing reports that Symantec Endpoint, and BitDefender are causing similar problems.Symptoms
- In all cases - an error in the licensing section - C:\Windows\system32\slmgr.vbs(291, 5) (null): 0xC004D401 - note that the numerics may change
- Avast - Typically, the problem will often show as both a Kernel Tamper, and a Mod-Auth Tamper – TTS Error: K:20110618155223762-M:20110618122132007- where the numbers are a numeric timestamp at around the time that the new version of Avast was installed – note that in some cases, only one of these errors may show
- Symantec Endpoint and BitDefender – these show a Mod-Auth Tamper - TTS Error: M:20111111153351704- - again, at about the time that the AV was installed
- Vista – only RTM and SP1 appear to be affected - builds 6000 and 6001
Hope this helps – and Good Luck.
- Uninstall the AV.
- Use Windows Updates to install all updates, and get to SP2 level, or install SP1 and SP2 from the standalone installers.
- Reinstall the AV.
- Check the solution works. Run another MGADiag report, and post the result in YOUR OWN thread – not someone else’s. If you don’t already have a thread of your own, start one, and tell us some background.
