Greetings
I own a 2400 celeron computer with 256 k ram and 80 gig hard disk. I use zone alarm, avg and adaware and keep them updated and religiously keep them active. I seem to however have picked up a virus/s which has slipped in under the wire.
AVG can recognise the virus however cant seem to remove the virus's, sometimes it says it does by deletting the file but the virus reappears. The actual virus's are as follows
c:\documents and settings\user\local settings\temp\1.exe: Trojan horse startpage.mf
and anotehr one

c:\documemts and settings\local settings\temporary internet files
pro_internet (1).exe

I have used trojan hunter without success. it would not even see the viruse was present and undertaken all the cleaning procedures given in thread PC Cleaning Procedures & Detection Tools including deletion of the files and also used
http://www.ravantivirus.com/scan/
http://www.bitdefender.com/scan/licence.php

and used the preliminary cleanup for hijack this and subsequent log is given below

Can you make any suggestions

Thanks

Kermie

You have some entries there that need removing.

===============

Open a command prompt by going to the start menu and then select 'Run'.

In the box that pops up type in 'cmd'. The command prompt will open.

OR

You can go to Start -> Programs -> Accessories -> Command Prompt. Unregister the dll(s) we're going to remove, by entering the following:

regsvr32 /u nsn100.dll

It's ok, if these aren't found or 'error' out. If you want, just copy and paste the individual lines to the command prompt to save typing them in.

===============

Run HiJackThis, click "Scan", then check(tick) the following, if present:


R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Search Bar = http://red.clientapps.yahoo.com/cus...rch/search.html
R1 - HKCU\Software\Microsoft\Internet Explorer\SearchURL,(Default) = http://red.clientapps.yahoo.com/cus...//www.yahoo.com

O2 - BHO: ohb Class - {98640C3B-0699-4D51-ADB4-A6FC48ACB966} - C:\WINDOWS\system32\nsn100.dll


Now, close all instances of Internet Explorer and any other windows you have open except HiJackThis, click "Fix checked".

===============

Locate and delete the following item(s), if present. Make sure you are able to view system and hidden files/ folders:

files...

C:\WINDOWS\system32\nsn100.dll

-

Note that some of these file(s)/folder(s) may or may not be present. If present, and cannot be deleted because they're 'in use', try deleting them in "Safe Mode".

-

Reboot.

===============

==

Clear out your Temporary internet files and other temp files.
Go to Start > Settings > Control Panel >Internet Options.

Under the General tab click the Delete temporary internet files,
delete all Offline content as well. Clear out Cookies.

Also, go to Start > Find/search > Files or folders > in the named box, type: *.tmp and choose Edit > select all -> File > delete.

Empty/delete the entire contents of the C:\Windows\temp folder and C:\temp folder, if you have one. (Contents but not the folder itself.)

C:\Documents and Settings\username\Local Settings\Temp\

In order to view these files you may have to select 'show hidden files/folders.' Instructions on how to here.

Empty the Recycle Bin.

==

After rebooting, rescan with hijackthis and post back a new log. Please let me know how your pc is now.

Thankyou for your reply

I followed the above instructions and logged on in safe mode to delete all the temp files etc.
Here is the new log

Regards and thanks again

Congratulations! Your log looks clean - good work!

===============

Now that your PC is clean you need to follow these easy steps to keeping it this way:

Secure your Internet Explorer by going here and following the instructions there.

Better yet, use an alternative browser! Download FireFox and give it a run. It is far more secure than Internet Explorer. Or, you can get Opera which in my opinion, is better still.

Use a firewall to help prevent your PC's control being usurped by undesireables. There is a link to a good, free firewall in my signature.

Install and keep updated, Ad-Aware SE, and Spybot S&D.
Run them both on a regular basis, following the manufacturer's recommendations.

Install an anti-virus. There are some good, free AV's available today. Make sure that it is updated regularly and have it scan your system often.

Check for Windows Updates. Microsoft regularly post updates for your systems safe running. Make sure to take advantage of this. Reboot when installed and return to make sure there are no others.


Clear your Temp folders.
Clear out your Temporary internet files and other temp files.
Go to Start > Settings > Control Panel >Internet Options.

Under the General tab click the Delete temporary internet files,
delete all Offline content as well. Clear out Cookies.

Also, go to Start > Find/search > Files or folders > in the named box, type: *.tmp and choose Edit > select all -> File > delete.

Empty/delete the entire contents of the C:\Windows\temp folder and C:\temp folder, if you have one. (Contents but not the folder itself.)

C:\Documents and Settings\username\Local Settings\Temp\

In order to view these files you may have to select 'show hidden files/folders.' Instructions on how to here.

Empty the Recycle Bin.

For XP users.
After something like this it is a good idea to Flush the Restore Points and start fresh.
To flush the XP system Restore Points.

Go to Start>Run and type msconfig. Press enter.

When msconfig opens, click the Launch System Restore Button.
On the next page, click the System Restore Settings link on the left.

Check the box labelled 'Turn off System restore'.

Reboot. Go back in and Turn System Restore Back on. A new Restore Point will be created.

Note that all previous restore points will be lost.

===============

If you have any more problems, post back.

Happy surfing,

crunchie.

Thanks for your help,

I havent had any problem with the virus since and I appreciate your help. There are still a few hangovers onthe computer I need to fix like the virus made my Word/Excel help display in such a small font that u have to peer very closly to see it but a fresh install will fix that.

One thing I cant see to fix is that my favourites in IE have dissappeared. Are they stored in a file anywhere. it was mainly junk but some where interesting I mean to revisit. I am taking your advice of moving to a diferent web browser so i will have the fun of collecting them againexcept my favourites

Again thanks

steven
