Hello, We are currently using ESET Smart Security and Business Antivirus in our company environment. Since updating to V4.XX we have had many problems with firewall rules, signature updates and also with the installation/uninstallation of ESET products. The ESET support recommended us to manually uninstall ESET Products, even if we only want to install an update from e.g. V4.0.417 to V4.0.424 . Manually uninstalling ESET products, in the way the ESET support told me (deleting folders, drivers, and zombie-services that haven’t been removed/disabled by the uninstall-routine), means approx. 20-30 minutes of work for every single client in an environment with more than 200 PC’s and Laptop’s . You may imagine that it is impossible for us to spend more than 100 hours of work every time ESET releases an update, only because the uninstall-routine doesn’t work properly. Please tell me how to handle this problem!?!
