Just updated my laptop (which hadn't been used for months) with ZA Pro 9.1.008.000. Machine seemed very slow, so checked Windows Task Manager and the process zlclient.exe was using 29% cpu. Left it running for an hour and still the same. Close ZA and cpu use drops to virtually zero.
So did a full uninstall (untick load at startup, safe mode, uninstall, ran cpes_clean.exe, checked that folders, logs etc had gone) then downloaded the new version again from ZA website (via Firefox) and reinstalled (selecting standard installation). Did notice that my reg code was still there, so must have been something left from old installation.
Problem still the same. Stopped AV program (Avast), no difference, nothing else running. Event log shows nothing suspicious.
My desktop PC works fine, most of the time zlclient.exe is showing 0% cpu usage.
Any idea what the problem is? Any other diagnostics to try?
(XP sp3, 2.4G P4 cpu, 1Gb memory, XP fully up to date)
