Cannot access some websites

Thank you for your help! Chkdsk still wouldn't work so I've taken it into our local repairer who will run detailed diagnosis on the hard drives, and then we'll decide whether to repair the files (if possible), or replace the disk!

Ended up rolling back to Windows 7 - after thorough hard drive testing by engineer, no faults were found, and he has had various cases of Windows 10 corrupting files, and also not interacting well with Kaspersky AntiVirus!

Hi, understand.. not heard of Win 10 corrupting files as such, but plenty of people have had issues upgrading and then incompatibilities with drivers, hardware or 3rd party programs. Hope you've not lost anything important.

Personally, this is early days for an OS. You have a Win 10 license for your particular PC, so you can carry on with Win 7, use disk imaging routinely and before any major change (Macrium Reflect Free, Aomei Backupper (free) - also gives a fully accessible backup.. and in a year or so try Win 10 again. However we feel about Win 7, ultimately new purchase hardware => Win 10 (or sthg completely different).

Yes, thank you!

The engineer suggested not upgrading to Windows 10 until at least after Christmas when hopefully incompatibilities will be ironed out... I'll probably leave it until July!

He also suggested BitDefender instead of Kaspersky as there are known issues with Kaspersky and Win10!

Hi, Bitdefender works on mine.. but I had to install a new version after upgrading from Win 8.1. Best practice is to uninstall AV/Firewall before upgrading. ESET (Nod32) has very recently been fixed- a minor registry issue ->desktop icon placement/explorer folder view settings being lost. (which was confusing as this is a very long running symptom from before Win 7)

Bitdefender does detect some Auothotkey compiled scripts (even after reporting this several times), and is not convenient in setting exclusions. Updating does occasionally slow things down, tho' not for too long.
