PC has ceased connecting to the Internet

[higgins]

I've been cleaning a friend's laptop of some atrocious virus, spyware and trojan dialer problems. I've got most of it licked, but have one big remaining problem: the laptop no longer recognizes the Internet.

MSIE was for a while summoning a dialer. No longer. But while it established a connecction to my router, it does not see that there's a high-speed Internet connection behind the router.

I've dug through various network settings but can't see any solutions. And it's definitely not just a browser problem. I can't get my telnet program to connect, either. There's no type of router security issue for a hardwired connection that I can think of.

This is a Toshiba Satellite, (Pentium 3, can?t figure out the exact model) It?s running Windows XP 5.01 SP1. I?ve run AVG anti-virus (479 infected files found); Spybot, Ad-Aware, Microsoft Anti-spyware beta and JV16 Powertools, plus I?ve updated Windows, though I haven?t installed SP2. (She's definitely getting Firefox, however, once I fix this other stuff....)

Any suggestions?? thx

I was thinking the LSP fix thing too. Try those and see what happens. Lots of time that affects only IE though so if you have Netscape on there you could try that and see if it works and just IE doesn't.

Wow, winsocks. I haven't thought about these since the good old days of installing Trumpet Winsock on my office PC to get it to connect to the Internet. Early 1990s?

Looks like LSPfix is the best one for me and Windows Xp Can't wait to try it. This is pretty maddening. "Yes, the good news I have guaranteed that you're never get more viruses and spyware on your laptop. It no longer surfs the internet."

TeraTerm telnet isn't working, so I'm assuming that it's more than and IE problem. I run Firefox on my personal machines largely for spyware avoidance.

Thanks for the tips, we'll see what happens...

Eeek. LSP-Fix does come with some pretty stern warnings... Into the Valley of Death. I hope a registry backup will be all I need to protect myself.

OK, I've run LSPfix on "basic" mode to no obvious affect.

I'm loathe to click the "I know what I'm doing" box, since I don't.
The "keep" window says:

mswsock.dll TCPIP
winrnr.dll NTDS
rsvpsp.dll [Protocl handler]

Should I be moving any or all of these to the Remove box, then his finish???

Just accept the defaults if I remember correctly. I believe I did the Winsock fix, not the LSP2 fix but it's been so long. Either way, your not going to blow your machine up running these fixes.

 

[higgins]

Great. I just like to make SURE before I muck with these things....thx. I'll try it tonight..

 

[higgins]

OK, I "removed" all three files, rebooted but still have the same problem. I connects to the my network, but not the Internet. What else should I be looking at? And should I do a system restore to pre-LSP Fix??? ?
