Thunderbird 115.11 gets seriously slow

Thunderbird 115.11.etc has become seriously slow when deleting or moving emails - the first one goes quickly but then it all slows down for the second and subsequent emails. I have found that this is a Virus checker issue - I use Microsoft's own defender software on Windows 11 - and have now eliminated the problem by making an exception in the virus software to the TB profile folder. My question is: how safe is this - I don't want to allow virus attacks in email but at the same time I don't want the slow software! What do you suggest? Thank you

You are still protected from viruses by Defender's other protection features. Since the real-time scanner is still turned on it will scan all the files and attachments in case you attempt to open or save them to disk. It will alert you if there is any infection. A malicious attachment just sitting in your Inbox does not impose a threat.
