You’ve run your primary anti-malware application, and up pops a notice advising you that you have an infection. But since you’re an aware computer user, you launch both your secondary malware scanners in sequence and – surprise! According to your secondary scanners you are not infected.
But, you’re aware that anti-malware programs that rely on a definition database to identify malware files, can often be behind the curve in recognizing the newest threats.
So, decision time. Do you then trust your primary anti-malware application and attempt removal, or instead, do you trust the results produced by your secondary scanners, and leave well enough alone?
In reality, you’re not really limited to just these two choices. There is another option open to you.
