I am having a problem with my friends computer where all of a sudden his DNS is not working correctly. His ISP has been no help. May have been hacked, but there is no virus except for this NHelper.com file (there are a couple others, but I can't remember what they are) having to do with adware.

We have access to the internet and can get to the sites (such as www.yahoo.com if we use the IP address but not the www.yahoo.com name). In IE, it starts flashing apps.webservicehost.com/apps/... extremely fast and when it stops the URL line has "apps.webservicehost.com/apps/epa?cid=navl9882&s=www.yahoo.com".

In Netscape, it just doesn't find it nor does it from the command prompt.

I am going to take my portable over there later today to see if it has the same problem. If it does, then it is probably a DNS problem. If not, it is probably a problem with his computer.

This started to happen when he got a message saying that a remote computer was trying access his computer. Norton did find 6 files, such as NHelper.com that were adware files.

Anyone know what the problem is and how to fix it?
Thanks,

Tom

My first guess in this is it probably could be some sort of spy ware or virus. I know my fiend had a similar problem when he typed in a URL it changed to something similar what you described.

The way I fixed it was run a Ad-Aware scan with the latest updates also I used Trend Micro free online virus scan which can be found at housecall.antivirus.com or (66.35.253.32). I found a couple of viruses on his computer that were cleaned.

I also did some googling for you and came up with this:

Sounds great.

I am going over to his house in a few hours and will try it out. If it works, I owe you one.
Thanks,

Tom

Also, I use both ad-aware and spybot on my system and like both. I did hear something about a problem with spybot and was curious if anyone else did.

Also curious about others experience with both. I planned on putting these on my friends computer - but want to be sure there wasn't a problem I hadn't heard of before I do.
Thanks,

Tom

Yep, that's another perfect 10 from me! I totally agree with Neon, it sounds like a spyware issue. You might want to check the startup tab in the system configuration utility by going to "run" and typing "msconfig".

I experienced a problem with IE where no matter how many times I ran spyware, it constantly found registration entries and files everytime I rebooted.

To eliminate the problem, I ended up performing a system restore.
It seems like these spy cookies and reg entries are getting tooo smart to be handled permanently by today's spyware programs.

Let us know what the results were!
