I keep getting hack tool detected

A_Shadow

Like i previously stated, every time I logg into crossfire it gives me that error Hack tool detected at least 2 or 3 times for the past 3-5 days. and it actually bans me every single time for at least a minute and i've tried looking for fixes for this issue now that its gotten annoying too the point were I actually had too make a post about this. Any solutions? ( I have a windows 7)
