Using SEP 11.0.6005.562 which gives numerous warnings about HTTP Tidserv requests for internet access.
Getting numerous browser re-directs & pop-ups (ad pages) symptomatic of this rootkit.
Downloaded the Symantec FixTDSS.exe removal tool but after execution I just get an infinite re-boot loop until I boot to last known good configuration and then the rootkit is still there (the FixTDSS tool just stalls after the reboot).
Also tried the Kaspersky TDSSKiller tool which identifies the Rootkit.Win32.TDSS.tdl4 object in the Master Boot Record, but again is not able to remove it as billed.
Would be very grateful if anyone has had any success in repairing this rootkit infection. Otherwise I guess it's reformat and re-install windows xp.
Many thanks!
