I usually try running Malwarebytes first. You can get it HERE
. Install, update and run it. If you have problems installing it then try renaming the file before saving it to your desktop. I like renaming it to bigmama.
Remove what MBAM finds and then install and run ATF Cleaner
(for Windows XP and 2000 only!). Check the box for select all and then click the button Empty Selected. This will help clear out temp files, cookies and other junk that clutters up Windows.
Next install, update and run SUPERAntiSpyware
. Get rid of what it finds. Finally update and run your antivirus program and get rid of anything that it finds.
If you have problems getting these installed and/or run then it will most likely be related to your admin issues. Let us knwo what happens and we will work forward from there. If you are able to run MBAM and SAS please post the logs in your next response.
