i hit a large snag on sat i was browsing around looking for a ribbon sorter of all things for my uniform. When i got hit by a trojan. AVG sees it as startpage.21.bi.
I have ran 6 diff spyware and trojan removers and AVG all up to date and all in safe mode.
Any one ever deal with this and know how to kill it? When it first hit i lost my internet explorer and my desktop. I have control over my desktop again but i know it is still here the active anti spyware is poping up every so often with warnings and blocks. Before whenever i try to run Internet explorer they all go nuts with warnings. So i am backto using netscape i dont thank it can get in to netscape. I havent tried to run it again for fear it may make it worse.
Please help

It won't be easy Plat.
Look at the posts here to get an idea. One person said AdAware with a special plugin may do the job cleaning. It will involve cleaning entries in your windows registry if it doesn't. I have a few more sites I will go to to look at solutions that have worked.
May want to try and save any personal files you want to keep and weigh the invested time in a re-install vs the hit or miss removal. I know I would personally try a couple shots of the step by step removal before throwing in the towel.
Good Luck!
Hopefully someone can offer more encouraging feedback.
