System32/svchost.exe Inbound Connection Blocked

Recommended Posts

Hi there, not sure what to do about this. Got a popup saying an inbound connection to an IP address was blocked. Ran a scan including "check for rootkits" and it turned up nothing, but as it's a System file I'm a little concerned.


Google search turned up more info than I can possibly handle myself.


Not sure if it matters, but it popped up while connected to a public wifi network.

Unfortunately I can't really get away from using that wifi network as it's my University's network.


I've redacted personal information from the logs. The post was too long with them cut/pasted in here, so I've just attached them all as .txt files.

The FRST logs are clean, no malware or infection. There was a possible browser hijacker (Open Candy) but malwarebytes has dealt with that... Bit of clean up with FRST, then one final scan....


Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into.
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Run FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.
