What are the symptoms of these 2 BUGS?

One of the steps in Major Attitude's Post above says that you only do a certain step if you have "about:blank or home search hijack". How do you know if this is one of your problems. What are their symptoms?

Thanks

 

The about:blank hijacker changes Internet Explorers homepage to a 'about:blank', This is not a real blank page, but pointing to some commercial site or search engine site. As of right now there are 8 variants of this hijacker. Some can be difficult to remove.

The home search hijacker changes your Internet Explorer homepage similiar to this "res://.dll/index.html#37049" It also adds specific Words on webpages link to search pages.

Both of these hijackers are very bad and need to be removed asap if infected.

If you think your infected please see this sticky thread When all else fails - Generic Solution to HSA (Only the Best) & About:Blank hijack
