If McAfee finds a trojan or similar and quarantines it, should I leave it in Quarantine or empty the quarantine folder? I had a trojan that Threatfire found and killed before it got any further and then McAfee found one during a scan and quarantined it. I'm a bit worried if I empty the quarantine folder, the trojan will be let loose on my computer!! Sorry if this sounds a bit silly, but it's the first time I have ever had a trojan or virus etc on my computer and I'm not sure how to manage them. Thanks in advance for your help.
