Slow updating

Hello,

I installed Comodo Free Antivirus 3 days ago.

Updates are taking too long. I manually (which I prefer) updated last night then again this morning - took 1 hour and 35 minutes this morning to complete? 100% CPU Usage mostly too throughout.

‘Install updates’ is the problem part.

Any ideas on how I can put this right please?

Also, does Comodo Free Antivirus protect against ransomeware and malicious urls - would I be protected if I clicked on a malicious link?

Thank you in advance.

XP SP3 / ClamWin Free Antivirus - which I will probably uninstall soon
