i used hijackthis - http://www.snapfiles.com/get/hijackthis.html PLEASE PLEASE PLEASE be very careful with this program! it’ll give you a list of programs and stuff, if you know a certain program that is harmful to your computer, fix it. and if you want to kill a process that cannot be killed, kill it on restart or something using killbox! ([URL=“http://www.bleepingcomputer.com/files/killbox.php”]http://www.bleepingcomputer.com/files/killbox.php) i really hope the links i’ve given are right. and then there are those registry values and keys they modify. the first step you must take is close the internet conn. so that new stuff doesn’t get into your comp… i hope this helps.
NOTE: in the registry editing process, they’ll tell you to turn off sys restore, and mostly tell you to go into the safe mode. please do what they say exactly. 
i suggest you write down anything that pops up on your infected computer like a url or a message. then you get on a diff computer, and then type that message on google and search for the virus, trojan name. upon finding the name (norton website is best for it. ie. if the virus were mssearchnet.exe then search “mssearchnet.exe norton”), you find out what registry values were modified, what keys were modified, and what files the trojan installed. KILL the files, and CAREFULLY (without messing up the registry) modify or add or delete the values or keys.
PLEASE DON’T CONNECT THE COMPUTER TO INTERNET YET.
restart, and once you know everything is clear and gone, then connect to the internet.
i really hope this helps.

3. To run the scan
[LIST=1]
[*]Start your Symantec antivirus program, and then run a full system scan.
Note: If you ran the Add/Remove programs applet as described in the previous section, all the files may have been removed, and thus none of them will be detected.
[*]If any files are detected as Adware.SurfSideKick and depending on which software version you are using, you may see one or more of the following options:
Note: This applies only to versions of Norton AntiVirus that support Security Risk detection. If you are running a version of Symantec AntiVirus Corporate Edition that supports Security Risk detection, and Security Risk detection has been enabled, you will only see a message box that gives the results of the scan. If you have questions in this situation, contact your network administrator.[LIST]
[]Exclude (Not recommended): If you click this button, it will set the threat so that it is no longer detectable. That is, the antivirus program will keep the security risk on your computer and will no longer detect it to remove from your computer.
[]Ignore or Skip: This option tells the scanner to ignore the threat for this scan only. It will be detected again the next time that you run a scan.
[*]Cancel: This option is new to Norton Antivirus 2005. It is used when Norton Antivirus 2005 has determined that it cannot delete a security risk. This Cancel option tells the scanner to ignore the threat for this scan only, and thus, the threat will be detected again the next time that you run a scan.
To actually delete the security risk:[LIST]
[]Click its file name (under the Filename column).
[]In the Item Information box that displays, write down the full path and file name.
[*]Then use Windows Explorer to locate and delete the file.
If Windows reports that it cannot delete the file, this indicates that the file is in use. In this situation, complete the rest of the instructions on this page, [COLOR=#0000ff]restart the computer in Safe mode[/COLOR], and then delete the file using Windows Explorer.[/LIST]
[]Delete: This option will attempt to delete the detected files. In some cases, the scanner will not be able to do this.[LIST]
[]If you see a message, “Delete Failed” (or similar message), manually delete the file.
[]Click the file name of the threat that is under the Filename column.
[]In the Item Information box that displays, write down the full path and file name.
[*]Then use Windows Explorer to locate and delete the file.
If Windows reports that it cannot delete the file, this indicates that the file is in use. In this situation, complete the rest of the instructions on this page, [COLOR=#0000ff]restart the computer in Safe mode[/COLOR], and then delete the file using Windows Explorer.[/LIST][/LIST][/LIST]
