AVG has started to try and get folks to use thier latest products,this has caused a few users to uninstall all security software and not bother!
I am starting to move away from AVG free to other free Antivirus products. I have been using Microsoft Security essentials on some client PC's and laptops. MSE seems to be doing the job.
I havee had to sort out a few Home pc's that have been using nortons Home security products, if you want to remove Nortons, first uninstall then run their Removal tool to tidy up. The tool is available on Nortons own site, would be best to download prior to removal. I have seen Nortons unistalls leave the internet unavailable.
As always don't just remove security software without then replacing it.
