Trusting antivirus is like trusting a horoscope.  
Can you believe that your antivirus is a kind of trash newspaper horoscope, that bases its report to you based on the moon phase ?</p>

I could not. Yet....

We know how the internet is full of bad viri (well, some corners of it really are).
We know how antivirus companies work hard to protect us from those bad bad virus-makers.
And since they work so hard we naturally think they work in most smart, intelligent ways.

They take a magic glass and scrupulously dissect every virus to know if it is dangerous or not.
At least that is what we must expect and hope.

It would be rude profanity to say that they just doing guesswork, throwing coins and summing numbers on calendars, won't it? Programming is the exact science, and so is protection of your private pictures and such. No one can tell if the program is dangerous virus or not just looking at the clocks and giving little attention to what the suspected program really does. It just cannot be.

Or at least you probably are used to think that way.

Now please, take a little time and compare these two links:

And those two as well:

You can see that some antivirus tools do hold to their opinions, whether they were correct or not does not matter. They made their decision and they are sure about it. But you can see many other just inversed their judgment. They have opposite assesment of those two files. So those files are probably different programs? Or not ?

позорный epic fail для антивирей, однако...
