security - How can I know my website contains Malicious code -

-

recently our website got hacked people , reporting below when try open our website

reported attack page!

this web page @ www.example.com has been reported attack page , has been blocked based on security preferences.

attack pages try install programs steal private information, use computer attack others, or damage system.some attack pages intentionally distribute harmful software, many compromised without knowledge or permission of owners.

at last came know there malicious code reporting in way... how can know code

i say, first, scan own pc ensure infection did not originate there. download site safe location(you may need disable antivirus software while purpose). have backup of original site before infection(or webhosting partner). make compare against infected content , should see difference.

if not have backup, scan infected scripts antivirus software determine specific files, need browse through code in these files , scan malicious code manually. worms/trojans append file, or specific tag, suspicious lines , parts of code not familiar.

(i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
