The problem was not caused by indexing, it just didn’t happen for a while. It
has been ok now for a few days but I am not able to give a definite reason as to why.
It was fixed after Microsoft Windows updates KB975496 and KB980408 were downloaded but I had also done other things to try and fix it.
Other things I had done.
Changed all npdeploytk.dll to Xnpdeploytk.dll so Java deployment toolkit no longer goes into Firefox as an Addin (Still had freezes after that)
Uninstalled Ashampoo DVD burner
Uninstalled Nokia OVI suite
Uninstalled VLC Media Player
Uninstalled Muvee Reveal
Deleted Ahead and Nero directories from c:/programfiles/commonfiles. these files were left after a failed installation of an incompatible version.
I do not think uninstalling these programs had any effect.
I ran services.msc and changed the following.
WWAN Autoconfig Manual to Automatic
Windows Time Manual to Automatic
Windows error reporting Manual to Automatic
SQL Server Browser Disabled to Automatic
Adaptive brightness Manual to Disabled
Com4QLBEx (HP quick launch buttons) Manual to Disabled
Hpqwmiex – HP stuff Manual to Disabled
I found that wiki.blackviper.com gives a fair bit of information about services.
(I still had freezes after these changes)
I had on occasions been getting Packed.it virus in shared folders and had been puzzled about it for a while.
Upon receiving one of them I checked through all events.
I found in Windows Security that a logon from network had happened at the same time and a user name had been created
This account had been given full control.
I initially deleted this account but when it happened again I made all its permissions Deny.
I also made permissions for “Everyone” to be only “List folder contents” and “Read”. They had previously been Full control.
Checking more through the security events I found many occasions which had logins with NULL SID login type 3 that had a workstation name and an IP address – seemigly hackers at work.
I have not yet been able to correlate the times of these with freezes so I am not sure if they were causing freezes or not but the problem needed attention.
Any suggestions of better security while still being able to use as shared files would be appreciated. I couldn’t really see a way, that I could understand, in windows firewall to do it.
The system now seems to be working very well – a pleasure to use without the freezes.
