A visit to the SEPTA online store (shop.septa.org) for comparing fares and passes led to the antivirus protection going off. The warnings noted multiple hijack attempts and high risk from that address. Don't know exactly what happened or if other SEPTA sites are affected, but please use caution. This is the first time I had such dangers from an "official" store, as opposed to "unofficial" or third party vendors.
Since my friend continues to chain smoke nonstop, she is probably an Alco.
