A computer in the Planning Accounting Department yesterday morning needed to be disinfected without being online. The simplest and most common method is to copy an antivirus software via a USB drive, and use an offline update package for the update. However, currently, most of the software that can be updated using an offline update package are domestic Chinese ones, such as Rising, Jiangmin, and Oriental Guard. Kaspersky only provides offline update services for version 5.0, while the disinfection speed of Kaspersky 5.0 is obviously slower than version 6.0.
