The invention relates to a secure file processing method. The secure file processing method comprises the following steps: a terminal collects file attribute information of a local target PE (portable execute) file when the terminal starts the anti-virus function, and calculates a file feature code of the target PE file; the terminal transmits the feature information of the target PE file to a server; the server compares the received feature information with a preset standard file feature library to determine whether the target PE file is infected by virus, generates different processing strategies according to the determination result, and transmits the processing strategies to the terminal; and the terminal processes the target PE file according to the received processing strategies. The invention also relates to a secure file processing system, a terminal, a server and probe equipment. According to the invention, the method can clean file-type viruses and repair the infected files based on the cloud computing environment without frequently upgrading the virus feature library, can clean unknown viruses and repair the infected files, and has the advantage of less user terminal resource occupied.

The invention provides a preparation method of plant antibacterial, antiviral, skin-care and health-care cellulose fibers. The preparation method is characterized by comprising the steps of preparingof a blended spinning stock solution, spinning and aftertreatment. Tea polyphenol and zinc elements are used for endowing the fibers with excellent antibacterial and antiviral functions, meanwhile, operation is assisted by the skin-care and health-care functions of collagen, so that the prepared functional cellulose fibers have antibacterial, antiviral, skin-care and health-care functions, the inhibition rate on staphylococcus aureus is larger than or equal to 92.6%, the inhibition rate on escherichia coli is larger than or equal to 93.8%, the inhibition rate on candida albicans is larger thanor equal to 90.3%, the inactivation rate on influenza A viruses is larger than or equal to 85.6%, the inactivation rate on influenza B viruses is larger than or equal to 86.2%, and the inactivation rate on herpes viruses is larger than or equal to 82.8%. The fibers contain multiple kinds of amino acid trace elements, and therefore good skin-care and health-care functions are achieved.

The invention discloses an application of a protein CbAE with a broad-spectrum antiviral function. The protein CbAE sequentially comprises a segment 1-segment 12, wherein the amino acid sequences of the segment 1 to the segment 12 are respectively as shown in the 72nd to 82nd positions, the 98th to 107th positions, the 109th to 114th positions, the 184th to 190th positions, the 218th to 242nd positions, the 232nd to 238th positions, the 273th to 283th positions, the 315 to 319 th positions, the 339 to 344 th positions, the 389 to 393 th positions, the 419 to 423 th positions, and the 425 to 429 th positions from the N end of SEQ ID NO: 2. Experiments prove that the fusion protein CbAE-1 and the fusion protein CbAE-2 can significantly inhibit novel coronavirus pseudo, novel coronavirus, HIVpseudo, DENV-2, ZIKV and HSV-1. The method has an important application value.

The invention discloses long-acting antiviral and antibacterial liquid, a preparation method thereof and application of the long-acting antiviral and antibacterial liquid in preparation of masks. The antiviral and antibacterial liquid comprises the following components in parts by weight: 0.5-2 parts of nano-silver sol, 1-5 parts of an organic antibacterial agent, 8-15 parts of a cosolvent, 5-15 parts of a polymer adhesive and 50-80 parts of water. The preparation method comprises the following steps: S1, mixing and stirring the organic antibacterial agent and the cosolvent in parts by weight to obtain a solution A; s2, adding water into the solution A, and stirring to obtain a solution B; s3, adding a polymer adhesive into the solution B, stirring, and cooling to room temperature to obtain an emulsion C; and S4, adding nano-silver sol into the emulsion C, and stirring to obtain the long-acting antiviral and antibacterial liquid. According to the application, the long-acting antiviral and antibacterial liquid is applied to preparation of a novel antiviral and antibacterial protective mask. The prepared novel anti-virus and anti-virus protective mask integrates the quick-acting and stable anti-virus and anti-virus functions, the lasting protection function and the like, and the defects that an existing protective mask is short in anti-virus and anti-virus time, complex in process, low in production efficiency, slow in effect and the like are overcome.

The invention discloses an aquatic probiotic with functions of lowering lipids, inhibiting inflammation, resisting apoptosis and anti-virus and its application. The present invention provides a strain of Cetobacterium somerae XMX-1, which is an indigenous bacterium in the intestinal tract of fish, the preservation number of which is CGMCC No.18908.
