Help- "This page cannot be displayed"!

I keep receiving this message "This page cannot be displayed" on my SBC Yahoo DSL browser (just installed) about every other link. I cannot "Refresh" and instead must hit "Back" and retry the link. It's getting quite frustrating. I have run a virus scan (EZTrust?) in the past week with no viruses found, but don't keep one normally running because I notice it gets much slower. I tried to run Pandascan but couldn't get it to download without an error message halfway thru.
Finally, I keep receiving error messages when my computer sits idle for a while, headlined with "YCommon, YBrowser, or YPager", and the last one reported that "YCommon caused an invalid page fault in module KERNEL32.DLL at 0167:bff7b9a6." I am forced to restart the computer. I have a notion that it's related to Yahoo Instant Messenger and just uninstalled it since I never use it, and we'll see what happens. Here is my HijackThis scan log, and I was hoping you might check it out to see if there's anything I can do. Thanks.

Firewall running?......that's the norm

Next just to save system speed you can shut these off.

C:\WINDOWS\SYSTEM\MSGSRV32.EXE.............(Not MSN messenger, windows server)
C:\WINDOWS\SYSTEM\MSTASK.EXE...............(do you have Scheduled tasks?)
C:\WINDOWS\SYSTEM\mmtask.tsk ................(MStask)
C:\PROGRAM FILES\COMMON FILES\REAL\UPDATE_OB\REALSCHED.EXE...(real player junk)
C:\WINDOWS\SYSTEM\QTTASK.EXE.........(quick time junk file)
C:\WINDOWS\JAVA\WAVEBAK.EXE...........(will start when you need it)
C:\PROGRAM FILES\COMMON FILES\REAL\UPDATE_OB\RNATHCHK.EXE ...(real player junk)
C:\WINDOWS\SYSTEM\HPZTSB04.EXE...................(printer software)
C:\PALM\HOTSYNC.EXE ......................................(palm pilot?)
C:\PROGRAM FILES\NIKON\NKVIEW6\NKVMON.EXE ........(photo software)

Do you use Adaware 6.1?.......remove spyware
get it here

NO firewall, at least not that I know of.

Thanks for the tips, but I've still got the problem. And I can't download anything right now- including Adaware. It seems to me that it's a connectivity issue where it goes in and out sporadically, and I momentarily lose my connection, interrupting the download. Yahoo tech support says my connection is good though. Any ideas for a computer "grape" like me?

 

Not sure if this will take care of your browsing problem, but these lines need fixing in HijackThis:

Educate yourself about spyware/hijackers:

And you really need to be running an antivirus and firewall.

Here's a good online AV:

Do you have a friends computer you could use to download and to disk?

 

What would you recommend as a good firewall?
Good work BTW on the other tips- Browser is running fine now. Thanks a million.
