When looking up the ip addresses that come up it is usually corporate. Sometimes it is overseas and unknown which really scares me.
About 2 months ago my brother in law(13y) downloaded what he thought to be a powerpoint upgrade. It did not say Microsoft and we started noticing this. We have eliminated the program and formated that PC's hard drive. Although now its mostly corporate ips coming up during that time it was all over the world and happening quite frequently. Now we always see attacks (some still unknown). I have tried disabling UPNP to stop this from coming up but it always seems to still come up although it happens less when UPNP is off.
Also is all the UPNP logs that come up normal? It happens alot when turned on and we don't run any apps. Thanks

Ask your ISP to change your external IP.
