This question was also asked on MSE. Does there exist an asymptotic estimate for the following sum over primes $$ \sum_{p\leq x} \frac{\tau(p1)}{p}\;, $$ where $\tau(n)=\sum_{dn}1$ is the divisor function?

8$\begingroup$ Please do not ask questions simultaneously on MathOverflow and Math.StackExchange. It leads to duplication of effort and is frowned upon by both communities. Please pick one site and wait at least a few days for an answer before reposting the question elsewhere. $\endgroup$ – Ricardo Andrade Sep 12 '14 at 18:29
For this kind of things it's always a good idea to check in the two volumes of the Handbook of Number Theory of J. Sandor, D. S. Mitrinovic and B. Crstici. Here I found the formula:
$$(\star)\quad \sum_{p \leq x} \tau(p  1) = \frac{315 \,\zeta(3)}{2 \pi^4} \cdot x + O\!\left(\frac{x}{(\log x)^\alpha}\right), $$ as $x \to +\infty$, for any $\alpha \in \;]0,1[$. Yu. V. Linnik. New versions and new uses of the dispersion method in binary additive problems (Russian). Dokl. Akad. Nauk SSSR 137 (1961), 1299–1302.
Using ($\star$) and partial summation (Tenenbaum  Introduction to Analytic and Probabilistic Number Theory, Chapter I.0, Theorem 1 with $a_n := \tau(n1)$ if $n$ is prime, $a_n := 0$ is $n$ is composite and $b(t) := 1/t$) you should be able to get an asymptotic formula for $\sum_{p \leq x} \tau(p1)/p$.
