Pfizer's Viagra advertisement recently caused an Internet storm when a large number of virulent Viagra advertising spam emails were widely circulated, and even Pfizer's own systems were infected. Now Pfizer has a hard time explaining it.
According to the intelligent email tracking monitoring report, because the virus is very hidden, many anti-virus software can not be monitored, so it can not get detailed effective data. But one thing is certain, this time the affected user area will be surprisingly large.
At present, Pfizer has denied that the information was sent by the company, but it does not deny that advertising and promotional sales companies may take such measures, and they are assisting the relevant departments to actively deal with it.
