And sure enough it does trip many antivirus scanners. Sorry but to kill processes and more, it may get classified as a trojan. Perils of being a power tool.
The one thing however is to get it from the source and not just anywhere on the net.
Hi - I had been using r.kill some years ago at the recommendation of Cnet moderators, to be quite sure I did not have any malware. But last week suddenly AVG alerted me to having a Trojan on three r.kill entries. They were disposed of by the program. But then the owner of my secondary computer (a netbook) opened hers and used Super to scan hers. Again r.kill was listed there as harboring a Trojan, on an inactive partition having an XP section called XP.old. This, I feel, should be brought to your attention.
