回答“Virus through WiFi router/Modem?”Hi John; your wifi per say can not be infected with a virus; although it can be hacked into and gain access to devices connected to your wifi and having the connected devices infected with a virus; someone must dislike you pretty bad to target your wifi for such malicious attack. In my opinion; your mention of surfing some adult sites might be your source of virus infection. I will recommend you get a good antivirus for all your devices.
回答“Why won't my mac power up?”Hi Kyle; you have been very thorough; but i have one question. Did you use an ESD Strap of any kind during your repairs? It is possible you might have a dead RAM; which might be caused by ESD. I have a similar situation where i actually fixed the "main" problem but created another by frying my memory modules since they are very susceptible to ESD; i hope this helps.
