Alrighty, a few days ago I got a pop-up stating I was infected and should download some spyware. Of course, I knew it was bogus and didn't click on it. However, I could not get the pop-up to go away, so I shut down my pc. Upon restart, the same pop-up showed up, and after 10 seconds, my system automatically restarted. I started up in safe mode, ran HiJack This, SmitFraudFix, and SpyBot S&D, which got rid of the pop-up and allowed me to run in normal mode. Since then, I have downloaded and installed BD and have been in the process of cleaning up my pc but still have some strange things going on.
First, my pc will not run disk defrag even though I have enough available disk space (18%) and have manually gone in and had it reinstall. In addition, I know whatever it is that infected my pc is still there because I still get redirected to advertiser and miscellaneous websites when using Firefox or Explorer, particularly when trying to reach sites related to anti-spyware and Microsoft as well. On top of that, this infection has hijacked my security settings in some way in that it is preventing me from downloading files from the internet such as some recommended by this site.
My latest scan by BD found an infection called Java.Trojan.Exploit.Bytverify in a zip file located at C:\Documents and Settings\Steve\Application Data\Sun\Java\Deployment\cache\javapi\v1.0\jar\crtdcghcn.jar-6425549-4fdf55b2 which contains 2 files, baaaa.baa.class and dvnny.class. For some reason, BD was not able to delete these files or do anything else. Right now, I'm kind of at a loss at what to do. Any help would be greatly appreciated.
