Hi,

I found the virus before and i did a re-install this weekend of my server but as you see it returned. The virus is rebooting my server randomly. It was gone for 3-4 days but the evening it started again. I'm going to shutdown the ClearOS server but I'm not sure what the infection source is. The first three are false positives. Nick also pointed this out. I also detected the three files when I scanned the ClearOS server after installation. The other looks like a Windows Trojan. I have only one VM on unRAID running Windows. EDIT: I scanned the Windows VM and it's clean. Please some guidance.

I'm not worried about the snort rules or the backup files (which contain the snort rules but the scanner is probably only returning the first hit). The other one is the same on mine. I don't have the time/patience for a full scan but:
[root@server ~]# clamscan -ri /usr/lib64/gconsole/browser

    I'm getting the impression that the others are also false positives but I'm completely sure yet. The only problem left are the random reboots. This server was before running Windows 10 and I was minning on it. It always preformed fine.
