I have few Qs in my mind regarding AV and AS scanners for a while. I will like to have any info about theses. 1- After a scan some scanners ask to reboot to clean the malware while others don,t. Why such a difference? 2- Ideally if some malware process is running in real time, it might be impossible to remove it without a reboot( if I am thinking correct). So what about the scanners that never ask for reboot during cleaning. 3- Why it is that almost all AV don,t ask for reboot while AS scanners usually ask for this? If reboot is required to clean spywares, why it is not required to remove viruses? 4- Viruses are almost always detected as files without registry enteries or memeory processes while spywares are detected as files, reg enteries and memory processes. Does it mean viruses don,t touch the registry? oOn the other hand if they do touch the registry, is it not imp to remove these reg enteries just like spywares? 5- Are these scanners always/ mostly have some special built-in tools that are used to terminate malware processes to facilitate the removal of the malware processes that are running in real time? Thanks for any input.
