I have a question for you. For my work I fix computers. Lately a lot of computers are infected with a virus. Under win9x I use f-prot for dos to delete the virus (in this way I don't have to install antivirussoftware). For win2k ore XP I use norton (the cd-rom is bootable). Is there a way to use the latest anti-virus software without installing software on a computer? I don't know if I can thrust norton because I can't upgrade the virusdefinitions when I use it.
