The main idea behind viral processing is to stop the viruses in a given sample from contaminating the desired product. The two most widely used methods of viral processing are viral removal and viral inactivation. The former is a method in which all viruses are simply removed from the sample completely. The latter method is one in which the viruses may remain in the final product, but in a non-infective form. These techniques are used widely in the food and blood plasma industries, as those products can be harmed by the presence of viral particles. Some of the more common viruses removed by these methods are the HIV-1 and HIV-2 viruses; hepatitis A, B, and C; and parvoviruses. The methods used in the plasma industry have been summarized (Horowitz B., Minor P., Morgenthaler J. J., Burnouf T., McIntosh R., Padilla A., Thorpe R. and van Aken W. G. Who Expert Committee on Biological Standardization. World Health Organ Tech Rep Ser. 924: 1-232, 2004.) In some cases, however, it is the virus itself that is the desired product, as is often the case with the HIV. In many cases, researchers may be trying to extract the viruses from the blood for study, not specifically for blood purification. It is also common to use these types of techniques to remove particles produced as a result of viral infection.
Methods, software and apparatus for detecting and neutralizing viruses from computer systems and networks
InactiveUS20080263670A1Minimizing chanceMitigating unwanted response time-outMemory loss protectionError detection/correctionData streamNetwork packet
Methods, software or computer programs, and apparatus for detecting viruses and mitigating their harm to computers communicating through a gateway node to another network are disclosed. Upon detection of a virus in an incoming data stream or plurality of data packets directed to a gateway device or node, the data requesting recipient is notified and provided with a plurality of pre-defined virus handling action options. If the recipient, or designated proxy, fails to select an action option, then a random selection is made. If a selection is made, then that selection, to the exclusion of other action options, is carried out. Thus, the recipient is empowered to dynamically select, as circumstances dictate and without future prejudice, the appropriate response upon detection of a particular virus. Action options may include data encryption and forwarding with recipient notification, or where email is the vector, attachment removal and location link insertion may be used. Software embodiments of the invention provide the machine readable instructions to carry out the methods according to the invention.
