I was told it is safe to run anti virus programs side by side. I believe the term used is layering. This sounded good "more is better" or is it The first line off defence already in place was Spy Sweeper. Spyware Blaster to follow, and then things got rather hectic. I started to do the updates in the Blaster and the Spy Sweeper asked permission to open access or block it, I stopped the download because the Spy Sweeper said it would change security settings. My question is, was I right to stop the download or should I have continued?
