Have you performed any anti-spyware scans? Have you tried doing your scans in "SAFE MODE"?

You need to start there first. If you don't have any anti-virus or anti-malware programs see BC's List of Virus & Malware Resources and at least scan with Ad-Aware and Spybot S&D. In #4 there is a list of several free online anti-virus scans which you can perform. I would also recommend that you download and scan with SUPERAntiSpyware Free for Home Users.

Then perform this online Virus scan: BitDefender Online Scanner. <- Add a check by "Autoclean".

Since you have Norton, see what they say about the spyware in the link below and how to remove it using the uninstall command.

Symantec has removal instructions for the NS variant but not for dealing with the ossproxy or MKSC variants via the hidden installer. You need to identify which variant you have, so that the appropriate uninstall command can be run. Sometimes running the usual anti-spyware scans will do this but you can use the Windows Search feature to search for any of the following files:

mksc.exe
nscheck.exe
ossproxy.exe

For the NS variant, at the command prompt type: cd %WinDir%\System
press Enter and then type: nscheck /uninstall
press Enter

For the OS RelevantKnowledge variant, at the command prompt type: cd %WinDir%\System
press Enter and then type: ossproxy -bootremove -uninst:RelevantKnowledge
press Enter

For the MKSC RelevantKnowledge variant, at the command prompt type: cd %WinDir%\System
press Enter and then type: mksc -bootremove -uninst:RelevantKnowledge
press Enter

For the MKSC Marketscore variant, at the command prompt type: cd %WinDir%\System
press Enter and then type: mksc -bootremove -uninst:Marketscore
press Enter

Reboot the computer and delete the following files from the Windows/System32 folder:
csloa.dll
csloa.dll
cusnns.bak
nscheck.exe
nscheck.lgc
nsconfig.dll
nsconfig.dll
nsconfig.inf
okshook.dll
osmim.dll
osconfig.dll
ossproxy.exe

When done, remove Marketscore security certificates from Microsoft’s Internet Explorer Web browser. To do this open Internet Explorer, click on Tools > then Internet Options.
Click the ‘Content’ tab > ‘Certificates’ button > 'Trusted Root Certification Authorities' tab and look in the 'Issued to' column for any “Marketscore Inc” or “Netsetter” certificates.
Delete any “Marketscore Inc” or “Netsetter” certificates by clicking on the certificate and then clicking the "Remove" button.
Click "Yes" in each confirmation window that appears when you delete a certificate.

Finally, change all your passwords.

Hi, I have tried to do scans in safe mode but it still seems to be there. I cannot acess any of the symantec pages either.

Please read and follow all instructions in the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". You may have performed some of these steps already. If you can't perform a step, then skip and continue with the next. In step #9 there are instructions for downloading HijackThis and creating a log. (This is a self-extracting version which will automatically install HJT in the proper location.) Do not post a log using the Beta version by Trend Micro as there have been reported problems and it is not being used by the HJT Team.

When you have done that, post your log in the HijackThis Logs and Analysis Forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. Please include the top portion of the HijackThis log that lists version information. An expert will analyze your log and reply with instructions advising you what to fix.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?".

After posting a log you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make may cause confusion for the member assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.
