One issue often overlooked with prostate enlargement is Nykturia. Nykturia causes sleep deprivation, sleep deprivation causes scores of other problems from cardiac issues to psychosis. I’d say ~ 3 times getting up during the night might be tolerable for most peope, > 5 times will cause problems.
AFAIK, clamAV hunts Window viruses, not Linux malware. The linux equivalent I know of is rkhunter.
