No nmb,
It is always good to ask questions, the right questions have made people wiser, because good anwers are explained in detail. There is so many malware around, 1,2 million last year, this year this number could easily double. Not a single av solution that can catch all these variants of malcode - viruses, trojans, spyware, riskware, adware, rootkits and what more nastiness one could feed a computer to get busted on or slowed down or compromised. Absolutely impossible to catch them all with one scanner, so we have to have several layers of defense, a combination of resident and non-resident scanners, online scanners that will not conflict with the resident av-solution, working normal user rights when not uploading or installing or when not needed. Surfing without admin rights is severely cutting back on the the payload of malware to harm a system. Using in-browser security, using a good two-way firewall, safe online practices, etc. etc. will get us on top of the 2,4 million issues of malware that could infect us. If we were extremely unlucky and had no protection at all we would have some of them on our computer. Iin short we call that closing the vulnerability gap on the machine in question by knowing how to protect ourselves,
