I'm not understanding whats going on. I attempted to perform a computer and a custom scan and neither would scan beyond 60%. I've downloaded the lastest version and uninstall the previous version before installing the lastest version. I also deleted the ESET folder before installing. Everything seems to be working except for not being able to scan. Can anyone help with this one. Thank you in advance. I'm using the ESET Smart Security v3.0.621.0. I'm running Windows Vista Home Premium 32bit.
