hijack this questions

By reading various threads I have figured out most of my hijack this log but there are a few remaining items I'm not sure of.

O9 - Extra button: Translate (HKLM)
O9 - Extra 'Tools' menuitem: AV &Translate (HKLM)
O9 - Extra 'Tools' menuitem: &Find Pages Linking to this URL (HKLM)
O9 - Extra 'Tools' menuitem: Find Other Pages on this &Host (HKLM)
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Default_Page_URL = http://desktop.presario.net/scripts/redirectors/presario/deskredir.dll?s=consumer&LC=0409&c=1c00
R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Search Bar = http://search.presario.net/scripts/redirectors/presario/srchredir.dll?c=1c00&s=searchbar&LC=0409

Can someone please advise what these are and can I safely delete?
Also....accidently got rid of systray.exe...hope I didn't cause disaster.(?)
Thanks!

 

None of these are bad, but not vital either. It's up to you. Systray.exe is a Windows system program, the one that displays icons of background programs in the right side of the taskbar. You shouldn't have deleted it. Unless you are expert in it's use, you should be very careful with Hijack This. Delete the wrong thing, and you will crash your system. Hopefully, you followed the instructions here at MG and have a back-up in case you have problems.

 

Thanks for the help. I did have a back up of systray.exe. I will be more cautious in the future. I do have one other one I am questioning.

R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyOverride = 127.0.0.1

Can you advise on this one also?
Thanks!
