just a "thought" - does she have a HOSTS file??
Pull up your hosts file in Notepad. The hosts file will be in %System%\drivers\etc\hosts where %System% is System32 in Winnt (Win2k) or Windows (XP)
The file has no extension, so you'll have to browse for "all files" instead of .txt
Chances are the virus has overwritten this file to prevent your accessing a variety of sites. For example one current virus adds something like this:
That essentially prevents your computer from accessing any of those sites.
Remove anything like that that you see. Unless you've modified the hosts file in the past, the only thing that should be in there is
Remove everything except that one. Then click File | Save
Don't do save as, because that will add an extension to the file and we don't want that.
I'm working on a friends PC that has:
Windows XP Home
Norton Antivirus 2002
Currently she is getting a notification from NAV that her virus definitions are out-of-date. The last time the virus definitions were updated was 4/21/04. According to her she has not changed anything on her system in several months.
The Norton license is up to date and expires March 2005.
Everytime Internet Explorer runs it crashes the system, this condition has been this way for over a year. Consequently she uses Netscape 6.2 instead.
When she runs Liveupdate it attempts to connect, it tries a scouple of times, but each time it fails with a message that indicates "Connection refused ..." to the liveupdate.symantec.com site.
When she tries to connect to either the liveupdate.symantec.com or www.symantec.com URLs via Netscape the same thing occurs (connection refused) and she is unable to connect via the web.
Running the command prompt and pinging "liveupdate.symantec.com" or "www.symantec.com" she has no problem, the pings are successfull, 4 replys out of 4 sent. So the PC is able to resolve the address and reach the host.
I am unsure if this is a simple NAV problem or if it is a bigger issue. I suspect it is a bigger issue but wanted to speak with others first,
I was going to see if she could get to the TrendMicro or McAfee sites as well. And if she can, see if she can try to run the free scans to see if there are any viruses on her system.
Also, I'd get her to download spybot to see if there was anything unusual running.
Any thoughts, experiences, or help with direction would be very appreciated.
