I'be been to a site called Shields Up! and have a report stating that my port numbers 80 and 443 are open, evidently leaving me vulnerable to hackers.
The test for file sharing was OK.
So, how do I rectify this situation?
I'm a bit of a dullard with technical matters, but I use my PC for research, and want to keep it as safe as possible.
Thanks in advance......
