Thank's
So, how to fix problem???? I have't internet conections
1 I had recovered tcpip.sys from file c:\windows\system32\tcpip.copy, just copy and rename to tcpip.sys
next step:
2 reinstall tcp ip protocol in properties of local area network connection, common\press install button, choose protocol \install from disk\ choose path c:\windows\inf press ok and choose tcp ip internet protocol, reboot system

if you set tcpip.sys in avast settings as exclusion its dosnt help, avast keep on blocking tcpip.sys but will not delete it. when warning about infections apeared, choose ignore and mark never ask again. Then wait for next update of avast.
sorry for my english, i am from ukreaine :)
Good Luck

Instead of reinstalling the TCP/IP protocol, you also could  open a command prompt (start -> run -> cmd.exe [enter]) and type at the commandprompt "netsh int ip reset c:\reset.log"

Windows restore will do the work

Guys, were those detections caused by an on-demand (i.e. manual) scan, or rather by a shield?

If it was a shield, could someone please open the file
c:\Documents and Settings\All Users\Application Data\AVAST Software\Avast\report\FileSystemShield.txt
search for the relevant entry about tcpip.sys (should be somewhere at the bottom), and paste here the few lines (the detection, plus the subsequent action(s) on the next line)?
Thanks.

I found a free tool to recover TCPIP.SYS:

It's worked for me.

I had the same problem yesterday. I solved it by system restoration.

I can't believe the trouble this has cause me (and others).  Took me 3 hours to get back to normal.  I got this Root kit warning for the TCPIP.sys but cause I know it's related to internet connection, I wasn't quick to let Avast delete it.  After an hour of googling the matter and going to the Avast forum (this happened the other day before this thread was started which seems to have helpful information), I finally decided to delete the file but then I lost the internet althogther after a reboot.  I did a system restore and got the file back and was able to connect to the internet and got the toll free number Avast offers and called.  The tech guy told me, after a look at my "Event Viewer" that I had many system errors and that was the cause of the file being reported as a RootKit and that I could select "Ignore" in the Avast drop down list when the warning came up again.
What a drag this was.

Did Avast Fix It In Today Update ? Because After I Format My PC Yesterday I Kept The Auto Update Off ? Is It Safe To Run It On Again Now ?  :o

Just hang in there and let Avast investigate the problem as it might take a bit long ;)

Edit: Beside I don't have this problem any way because my avast didn't detect my tcpip.sys as a virus because I have XP Pro SP3, so I have no problem at all as mind say it clean.
