|I personally check files mentioned in HJT log on www.processlibrary.com - if it is unknown or shows malicious - very likely you should fix line containing this file because PL contain pretty full database of known files.|
I remove lines containing (file missing) or (no file)
Lines containing hosts entries or proxy settings - check if website mentioned is goog or bad (f.e. on Google).
Read carefully about each line (O1-Ox) etc. Send here your if you want an example of analysis.
