I'm looking for a small app that I can install to scan my system for malware. I do not want "active protection" of any sort. I don't want new entries appearing in my services configuration. I don't want any new background processes. I don't want email, boot sector, memory, etc protection. I just want a scanner that runs when I tell it to and closes when I'm done. They don't seem to make anti-virus software like this anymore. Every app I've come across has been loaded with garbage that clogs up your system. You can't even terminate most of these apps without uninstalling them. Not even AdAware works the way it used to. I've tried AVG, Avast, Norton, NOD32, Kaspersky, and others whose names I've forgotten. I use Anti-Malware now but that's it. I'm looking for a bona-fide virus scanner of the same sort, but maybe there aren't any?
