I removed Total Security 2017 with the removal tool and went to Bitdefender Central and downloaded TS 2018. All was fine, then all of a sudden I could not load loads of websites. Skype, OneDrive, Adobe Creative Cloud were offline too!
I pinged some sites (including ones that I could not access and they pinged OK. Also, accessing them on my cell worked fine. Google and YouTube were the only ones I could access. Chrome was allowed in the firewall and nothing was blocked. Same in the new Threat and Ransomeware modules. Other browsers were blocked too and I refreshed my Network adaptor and removed Googles DNS. Nothing solved the problem, even disabling the firewall and all the modules in BD TS 2018.
I removed Bitdefender 2018 and all was OK again.
What would have caused this? Because I want to reinstall Bitdefender Total Security 2018, but I don't want this to happen again.
