lazarba,

Have not forgotten you. Did take a look at the reports provided, and at first review, have not seen malware entries. Need to look at it more thoroughly, though.

Since the following driver has been questioned in your previous thread:
C:\Windows\SysWow64\WinFLAdrv.sys

Please run the file though one or more file scanners, and let's see if there are any malware detections:

VirusTotal

Jotti's malware scan

ThreatExpert - Online File Scanner

VirSCAN.org - Free Multi-Engine Online Virus Scanner v1.02, Supports 39 AntiVirus Engines!

Comodo Instant Malware Analysis


Also, please check the following file:
C:\Windows\SysWow64\WinVDEdrv.sys

If you get a message saying: File has already been analyzed, click: Reanalyze file


Please post the link to the results of the scanners chosen.
