Trial factoring (TF) is a preliminary step that eliminates possible candidates by finding small factors. Factor found = not prime.
For proving a prime you must run "first time Lucas Lehmer tests" (LL) which you seem to have demanded from Prime95. But if your PC is relatively slow PrimeNet will assign less demanding work (for example TF).
Could you add your PC's hardware?
Last but not least: Welcome to the fun world of finding primes and factors.
