Almost every time I write an article about some web site or perhaps about a Windows program that can be downloaded and installed on your computer, I will receive at least one email message or other report from someone saying something like, “I downloaded it but my anti-virus program says it has a virus or a trojan”
My response usually is, “Well, maybe…”
In many cases, the claim of a virus or trojan or other malware (malevolent software) is a so-called “false positive.” That is, the anti-virus program reported a problem that isn’t really there. In fact, there is no virus or other problem at all, but the anti-virus program thinks there is. All anti-virus programs will occasionally report “false positives.”
How do you determine the truth? Actually, there are several ways.
