About a week ago i installed ESET smart security and would like to leave my feedback as a first time user. I was previously using AVG9 and my computer was running very slowly and programmes such as internet explorer were taking a long time to load. After uninstalling AVG9 and installing ESET i must say i am surprised at how much faster my computer is running. I was planning to install ESET just to see how it ran and then do a clean install, but my computer ran so well i felt a clean install was unnecessary. Overall i am very pleased with my purchase and the responsiveness of my celeron laptop since installing this software.
