I call these "cockroaches" as they have resisted all my attempts to kill them. I run the following at least twice daily: SpyBot/SpyBlaster AdAware CCleaner Additionally, even though I don't use IE, I have just run the MS Beta anti-spyware full test. I also have Avast as resident anti-virus. The "cockroaches" which have proved invulnerable to these precautions are: Httper ABetterInternet WebSearch Toolbar Seekerbar Hijack Websearch.Com Hijacker Three of these:ABetterInternet, Seekerbar Hijack and Websearch.com Hijacker have appeared since yesterday. Any suggestions as to get rid of these "Cockroaches" would be welcome.
