Not being online much for the past couple of days because of more computer problems

specifically to the anti-virus software again
Long story short it updated and it was just crashing continuously and repeatedly about every two minutes. At one point I thought my hard drive had bad sectors because the nt kernel was crashing. It took a long time to figure out. In the end I restored Fridays backup and everything worked fine until I connected the Internet backup and the anti-virus downloaded updates of then started crashing repeatedly. I've been battling it out with ESET support who released pre-release updates, which solved the problem.. Then two hours later it updated again and started crashing again
Another long story short they said earlier
The issue has been pinpointed and should be resolved in version 1245.1 of the Cleaner module, which is due for release later today.
One thing I only just really found out as I could rollback updates within ESET. I went back 10 updates and it looks like the version numbers of the modules which I was running on Friday. It has not crashed once since using earlier versions. So I presume I will get a email at some point tomorrow saying they have fixed the problem.
Is a wonderful thing to happen Monday morning ! Did I mention I hate computers ?
EDIT:
Finally fixed. They said.
We do not develop the software here in the UK but my understanding is some third-party software does not correctly write values to the Windows registry and our Cleaner module 1245 did not adequately account for this, causing the ESET kernel to continually crash and restart.
