trbon2001,
Someone else may have a more definitive answer, however IMHO there are a few things you can do.
1) Be sure you have erased all previous restore points by turning off system restore. Once you are sure everything is cleaned, you can turn System Restore back on again.
2) Again, delete all temporary internet files, cookies and history.
3) Go to "START" >"Run" and type in: %temp% click Okay and delete all of those temporary files.
4) Manually Run Live Update for NIS 2008 and do another full system scan in both Safe Mode and Normal Mode.
5) Update the definitions for Malwarebytes and do another full system scan in both Safe Mode and Normal Mode.
6) If all scans report that your computer is clean, then:
7) Observe your computer over the next few days making sure that everything is performing normally.
I generally advise against using your computer for any online purchases or financial transactions until you are certain there are no more issues left.
The folks on this forum have suggested reliable and proven removal tools, so don't be tempted to download something else to check your computer - you may be asking for more trouble.
At the first sign of any suspicious behavior i.e. Website redirects, sluggish functioning, high CPU usage or anything else unusual get back to us and we'll try to help.
Last, but not least - do not click on unknown warnings which may appear in the future. The infection you had, Antivirus XP 2008 is user initiated. A fake message appears notifying the user that they are infected and that the cure is just a "click away". As soon as the user clicks, the infection is downloaded.
Best Wishes,
Phil
