I recently had to clear some viruses and malware off of my computer, and I did, but something still seems weird. During the infection, my internet connection was always wirelessly through my router. Now, I know it's not a problem on my ISP's end, since I'm able to connect fine through just the ethernet cable that is connected to a box which converts it straight to a cable line (Not a modem...A technician came and put it in, and there isn't a power cable going to it or anything). I'm not having any problems right now, since I'm not connected to my router. My Xbox 360's connection was also affected by this, meaning it would have connection issues as well when it was connected to the router. My question is, is it possible that a virus/malware could have somehow affected how my router functions? Such as an infected firmware being installed, or something? I don't want to connect back to my router until I know if it was affected or not, and how I can fix it if something is wrong with it.
