How do I remove ad-aware web search engine from firefox?  I've uninstalled all of Lavasoft's programs from my pc.  I've removed it from Internet Explorer.  Reset and removed it from Firefox options under the search tab.  I've used my webroot to remove threats that have popped up several times over the last 2 days.  I've used malware and its not finding anything.  I read up on the ad-aware and articles are saying its in the bootkit.  I don't know what that is.  The instructions are too advance for me.  Its been suggested I buy Spyhunter to get rid of it.  I don't know what that is and never heard of it until today, so I'm not buying it.  I did read up that the ad-aware web search engine is know for hidding viruses and other nasty things deep in your pc where it hides. I need help, I just bought my pc, a few days ago.
