A customer calls saying since renewing NIS, her PC is running unbearably slow.
Looking at the PC, I notice a few strange things:
- NIS is installed (but causing PC to run very slow)
- An older version of NAV is also running
- It looks like the older NAV is part of Norton Systemworks
- During a reboot, it also looks like Norton GoBack is also running…
The user says that she just wanted NIS, but since she didn’t understand most “prompts”, she just said OK to all of them (that explains GoBack).
The first thing I try is uninstalling NAV and NIS in the official way (add-remove programs)… but it fails (after 20 minutes of waiting)… OK, time to get ruthless.
I disable all symantec tasks in the startup folder, registry, and services
I then reboot and I’m pleased to see the PC is now much faster.
I try to remove GoBack, but it also fails. So I lookup how to manually remove it (from the net)… It involves a few reboots, but I manage to disable it completely.
As an aside: why would I want to disable GoBack? Under some circumstances, it can cause a HUGE slowdown in your system performance. All it takes is something (that GoBack doesn’t recognise) to write to the disk quite intensely (eg a disk defrag program not recognised by goback).
I once had a problem with a huge slowdown a few weeks after installing GoBack… I didn’t know why… its just so easy to forget about GoBack once it is installed. Once I figured out what was going on, I removed GoBack and vowed never to use it again. If you like the idea of GoBack, then do a daily backup to a second physical disk instead… it works much better.
Anyway, I now manually remove NIS, Systemworks, and any other Symantec application. Everything seems to work well, but I’ve run out of time (customer doesn’t want to spend more than 2 hours worth).
Since she seems to have lost the NIS install file that she downloaded from the internet, I tell her she should download the file again, then try installing it again (and if she has any problems, to give me a call). This way I won’t spend up to 1 hour waiting for a download to complete, and another 30 Minutes installing and configuring NIS.
