I got my laptop back after a terrible ordeal to get it repaired under warranty when it died a few weeks back. I still don't know what happened but it was very similar to what happened to many AVG users on 11/11 when they downloaded an update that deleted an XP file and killed Windows. http://www.computerworld.com/action/article.do?command=viewArticleBasic&articleId=9119848 I have AVG on all my older machines but I am still not sure I had it on the notebook because Norton was running on it and I don't think I would have installed AVG on top of Norton. But now that I have read all about what AV programs can do I am seriously considering not using any. I rarely do the updates and rarely scan anyway so what good is it ? I scan with S&D and have a firewall. ( XP's or then ZA). The odds that you will catch a virus are actually much lower than the odds of experiencing problems with those programs . And then good luck to get help from support ! if you go to http://freeforum.avg.com/ it's a litany of problems posted by users who apparently still continue to use the product ! It's not just AVG, ALL antivirus programs have had their share of hair raising bugs. So how do we live without them ? I don't want to ever waste my time and raise my blood pressure because some timewasting developer somewhere screwed up their latest "update".
