Hi,

:) I am a new forum user so forgive me if I have missed out anything/put something in the wrong place etc. etc.
I am not an expert but can navigate simple DOS, regedit etc. :thumbsup:


I have recently had a problem with explorer.exe on my work laptop. It started when for some unknown reason my laptop switched into safe mode? I thought this was a bit odd and I may be under attack (I am constantly connected to the internet via my wireless router at home). I forced the laptop to close in the hope of preventing any hijack before running too many scripts by holding down the power button until the laptop powered down. The laptop started OK again and was ok the rest of the night but the next day when logging on I kept getting to my desktop and after 5-10 seconds all of my desktop icons had disappeared and I got an explorer.exe I/O error. I even got this in safe made and every other mode when starting up, I even tried a restore to a previous point via simple DOS commands without success. I eventually got an old XP disc out and repaired the OS that way and everything seems fine. I have trend micro office scan client virus scanner taht was on the laptop when i inherited it but I have no idea how effective this is or if the company pays to keep it updated so I have installed avast anti virus and spybot s&d to prevent this happening again.

That's the senario but my question is:

Please see my hijack this log below. Could you check and advise if I have anything suspicious that could have caused the corruption in the first place or if you have any idea what virus this could be so I can clean up unwanted files? :)
