For the past week and a half I have been plagued with viruses, the worst of which I believe to be the Vundo virus. Three times I have presumably cleaned my machine only to have it become infected again. Each time I am greeted with an Internet Explorer dialog box (I use Firefox) which reads, "Attention! If your computer is struck by the spyware, you could suffer data loss, unusual PC behaviour, PC freezes and crashes.Detect and remove viruses before they damage your computer!Antivirus 2009 will perform a 100% FREE and quick scan of your PC for Viruses, Spyware, and Adware.Do you want to install Antivirus 2009 to scan your computer for malware now? (Recommended)".
Each time I have quickly terminated IE using the Task manager, but the trouble starts anyway. The virus or viruses have caused popups, computer crashes, and blinking desktop items. I have seen similar cases documented on the internet and have used various tools to clean my machine. It seems that every time I feel that I have thoroughly cleaned the computer the infection recurs.
When using MalwareBytes, Combo Breaker, Hijack This, and other programs I have found many viruses, but the most prevalent would be Vundo and Seneka. The last attack put three strange dll's in my startup folder; higihape, vuwizodi, and vepuhuje. I unchecked the items and I believe they were deleted while cleaning the machine but they are still in the startup folder.
I read at Wikipedia that Vundo exploits a vulnerability in Sun Java and have since reinstalled it. My computer seems to be clean for the moment but I would like to prevent this from happening again.
Thanks for any help.
