Latest update to AVG is crashing my computer.

I started having problems with AVG Free on July 22nd. Up until then it
had worked flawlessly for 6 months and I was very impressed. After the
22nd it didn't update anymore so I posted here and was directed to the
AVG forum where I found I had to remove the upd7avg folder contents (or
something like that) and it would update.

I found a better workaround myself. I updated to the July 22nd
installation source and it seemed to work as normal again.

Then we come to August the 19th. I was actually running a scan while
the file was downloading so I thought I had better stop the scan. The
system refused to reboot when I restarted it and I had to uninstall and
reinstall my 22/7 installation. Then today another big system file was
downloaded. Yet again the system wouldn't restart and I had to uninstall
and reinstall AVG.

I'm not sure if I should turn update off now. If I'm going to download
buggy updates I'd rather have something outdated that works than
something up to date that crashes my computer.

I am running Win98 first edition, AMD K6-500, 128Mb RAM. I'll check the
AVG discussion boards but I thought I would make people aware of the
problems I'm having with AVG in case someone knows the answer.
