I recently experienced some problems with my computer and I ran a malware scan. It identified a "Backdoor" virus (not such a good thing).
I am not a computer expert, and maybe I've got this all wrong, so do NOT impute any guilt or veracity to my results.
The log shows the virus was extracted from my Pro-ethe--e folder.
If anyone is more knowledgeable about these things, please don't hesitate to advise us.
