You are talking manual exclusion.No there is no quarantine, i think there is no need, you can add files, website's, applications to exceptions...
this is actualy no problem for me , its very simple to use. i think i will stay with Sophos
Why would you want to restore malware ? hehe
No product is FP proof. And you never know when an imp file detected as malware or bad signs in the database/cloud, etc...& poof things deleted.There are No FP's , either it detects malware or its detected as a PUP, when it is a pup you have the option to allow it or remove it.
On what files are you affraid off being deleted ?
