After several years of safe internet practices, I must have gotten complacent or careless, because MS security essentials popped up telling me I was infected with numerous trojans, of which Kovter was one.
Numerous attempts to self-treat were only partially successful, as each time the machine is restarted the malicious files are re-installed, (...appdata/local/Ektion/(randomname).lnk, ...Windows/temp/(randomname).exe, etc.), and startup entries try to launch. Listed below are the malware scans I've run, and their result.
My uneducated guess is this malware is "file-less", or nearly so, and full removal may require manually modifying the registry, putting it well above my ability level to solve. I will not make any more attempts to diagnose or treat the infection until told to do so.
1. MS security essentials: initial detection. Ran full scan, removed all items. Currently running in background.
2. MWBAM: Ran full scan, found infection again, removed all items.
3. RKill: Ran.
4. Hitman Pro: Ran full scan, found infection again, removed all items.
5. Zemana: Ran full scan, found infection again, removed all items. Currently running in background.
6. Appguard: Installed as last resort to buy time to address issue. Currently running in background.
I greatly appreciate any help you can provide. Thank you very much.
