I recently clicked onto my Mcaffee firewall icon to find alot of programs granted full access to internet from my computer that I did not authorize.My son has installed a program called called limeWire where he gets music downloads from some kind of file sharing system.I think part of his download gave access to these programs. Is this bad? could someone get important information from my files? what would they be after? I have my banking info on Quicken and some websites I access to check banking,investment,and CC info from. Could they get my passwords? and who would they be? I just dont know about this stuff.Should I be worried.
