i couldn't really understand your code, but this is how I'd do it:

Under The defines

pawn Код:

forward Virt();

Under OnFilterScriptInit or OnGameModeInit

pawn Код:

public OnFilterScriptInit()
{
    SetTimer("Virt",2500,0);
    return 1;
}

Any Place on the script, except inside other callbacks.

pawn Код:

public Virt()
{
    for(new i = 0; i < MAX_PLAYERS; i++)
    {
        if(IsPlayerConnected(i))
        {
            if (GetPlayerVirtualWorld(i)!=0)return BanEx(i,"Virtual World Cheats");
        }
    }
    return 1;
}
