Emsisoft Emergency Kit review

Emsisoft Emergency Kit is the toolkit to carry on a USB stick when you fix other people's computers. It is fully portable, so nothing gets installed on the infected machine, and Emsisoft says you just delete it after use. It packs the same dual-scanner technology as Emsisoft's endpoint protection, and its cleanup goes beyond deleting files: it quarantines or removes detected objects and their artifacts and restores damaged system settings. The graphical Emergency Kit Scanner suits most users, and the command line scanner, a2cmd.exe, lets technicians script scans with options such as memory, registry traces and archive scanning. Updates come with one click. Emsisoft also promises personal expert malware removal guidance for hard to remove infections. The catch is age of hardware: the current version needs Windows 10 64-bit or Windows Server 2016 and later, so older PCs need another tool. It offers no real-time protection; Emsisoft sells Anti-Malware Home for that.

Who it is for

Technicians and confident users who clean several PCs from a USB stick.

Price

Free portable scanner; Emsisoft Anti-Malware Home is the paid real-time product.
