Hi Blind Dragon.
I run AVG Anti Virus, AVG Anti Spyware, Sophos Anti Rootkit and A Squared Anti Malware on my PC. No malware is detected by them. My browser is not hijacked. I also ran the online virus scan at Trend Micro. It came up with a few security vulnerabilities which had to be fixed using Windows Update by downloading some new updates. My PC is running fine. Can't I just remove the rootkit using AVG as Kimsland suggests?
Now the rootkit is detected as apl7a7wx.SYS and not as a5c6zkou.SYS
Even after following the instructions of showing hidden files through explorer I could not locate the file. Can I safely remove it?
