Emsisoft has a solid lineup of security software (currently being rebranded from previously used a-squared naming) and their Emergency USB Stick files pack caught my attention. What can I say – I am an addict of any and all portable antivirus software. :)
What it does
Portable version is package with two Emsisoft programs (Free and Command line scanner), modified to work without installation.
Download is simply a ZIP archive and app is ready to be used right after unpack and prompt to download latest signature definitions.
There are several scan profiles, including custom, with full scan of all files being default.
App is very thorough (read it – takes its time) with scan and maybe even too thorough with browser cookies. It plays better safe than sorry.
Self-update and command line scanner are functions both rare and welcomed in portable antivirus.
Download size is very considerable at almost 90MB as of writing this post. Most of this seems to be signature files. Portable scanners usually manage to keep their signatures much more compact. Size matters when you need to quickly fetch scanner from Internet on possibly slowish connection.
Earlier version stuck its service in the system, but this doesn’t seem to happen with latest one. Still service executable is still present in download, so it might be used for some specific tasks.
Interesting balance of features – heavier than most command line scanners, but closer to fully featured antivirus solutions as well. Free for private use only.
