IBFX and Tr/crypt.xpack.gen

While installing an IBFX demo, my AV software ID'd a virus/trojan called TR/Crypt.XPACK.Gen. I quarantined it and started the platform. Everything was normal except Expert Advisors were grayed out and not functional.
Anyone heard about this?
I contacted IBFX. They said it wasn't their bug. Had no solution. Recommended removing MT4 and downloading another. Same thing happened.
Then Avira found another bug during defrag, this one called HEUR/HTML, which is part of the same family as the first bug.
Could IBFX be doing some sneaky shit?

Not necessarily, a more likely reason is a false positive by your AV software.

A false positive is more or less a suspicion that the said file is a trojan / virus or whatever.

A virus is an executable file and a trojan resides within the executable or possibly the program installation itself. There is usually some "trigger" event that causes the trojan to execute.

The problem is in order to install a program you need an executable file along with an "installer" depending on how these files are packaged may determine why you are getting this "trojan" warning thru your av software.

For this reasaon it is very common for software developers to tell you to shut off all AV software while installing their software because they know it will trigger a false alarm.

Thanks.
