Explorer.exe freezes when F-Secure is processing a threat
I have noticed that when F-Secure detects and processes a new or complex malware sample (typically detected as Trojan:W32/Generic.xxx!Online or something like Trojan.TR/Crypt.XPACK.Gen) and I right click on it, Explorer.exe is likely to temporarily freeze. After the disinfection process completes, everything returns to normal.
In my opinion, this is probably because F-Secure is looking for online virus definitions or employing some advanced heuristic detection technique to identify and remove new threats.
That being said, I still hope F-Secure can improve the detection and disinfection process, so that Explorer.exe does not freeze or crash.
It's hard to say since there are many variables that could affect that. It could be the disinfection process that took quite a lot of the resources which could contribute to the freezing.
A similar case that was recently reported had no freezing issue reported but if you face such in the near future, there could be need for you to get a diagnostic log for us to investigate further.0 Like
