Hi This is a bit of a newb question but I'll ask anyway. The second part really crosses over into Software and Services but if I don't like the answer to the first part then the second is somewhat redundant. Okay - scenario. Computer A- sits on a Broadband connection behind a Netgear router with a free AV and no other resident protection. No real reason to think it is infected at present but Spybot did detect a keylogger and fixed that problem. However, no guarantee that it is clean. Computer B- Laptop on a dial-up connection. Resident NOD 32, LooknStop,Counterspy, SSM full, PG full, ShadowSurfer and Spyware Guard. Various other on-demand scanners. Never any sign of infection and as reasonably sure as one can be that it is 100% clean. Question is, if I connect the laptop to the broadband connection therefore I guess, effectively networking the 2 machines, if Computer A is compromised in any way does that mean the laptop is vulnerable to cross infection, and if so how ? Secondly then. If I can be sure that the laptop has no chance of being compromised, what do I need to do to physically to hook the laptop to the broadband connection (cabling etc) and how do I configure the laptop to accept the connection. Sounds like LnS is a bit tricky to configure behind a router but I'm a big fan so would be reluctant to let it go. Thanks for reading and hope someone can give some guidance.
