I ran a full system scan on my laptop and was watching the files it was scanning and it said it was scanning "Infostealer.Snifula.B." on my c: drive. I kept watching norton scan my hard drive and also saw "backdoor rustock b" and "rustock a". Norton 360 did not recognize these items as threats but did quarantine other files. My question is whether Snifula/rustock a/b are actually active on my computer? Would Norton 360 miss these threats?
In addition I ran the same scan on my desktop and the same process occurred.
thank you for your help
