I'm posting this for my sister's neighbor.
We have a Windows 7 desktop that was running slow and would not access any site other than cnn.com or other news sites.
It had Norton 360 on it and an error was saying it did not have updated signatures.
We ran MalwareBytes on the computer and it cleaned up quite a bit.
We couldn't get around the Norton 360 error so we uninstalled it and installed Avast. Many things were found and removed by Avast.
However, after booting up in safe mode and attempting to clean it up (all with her doing the work since I can't even remote into it) we are posting here for help!
Since the computer will not access many sites, including bleepingcomputer.com, we will need to download any programs from another computer to a USB drive and run them.
We even tried to purchase a new program but she couldn't find any local sources, only keys with internet downloading. Not helpful in this case.
She just attempted to go to bing.com and got the following error:
This page can't be displayed
Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to
https://www.bing.com again. If this error persists, it is possible that this site uses an unsupported protocol or cipher suite such as RC4 (link for the details) which is not considered secure. Please
contact your site administrator.
Also, Avast popped up a small window in the lower right saying that the site certificate was invalid. It does this for many sites, not just for the above.
We will not do anything else to the computer until we hear back.
Thank you for your help!!
