Windows XP SP 3. Dell Vostro 410.
Attempting to run MBAM, which I have previously installed awhile ago, gets blocked with the message that the files infected. Attempting to run my Avira Antivirus is met with a similar message about it being infected. Attempting to run process explorer results in similar error messages.
I can't even bring up My Computer properties as the rundll32.exe gets met with the same error message.
Windows Security Center keeps popping up.
Also, www.[bleep].com keeps getting launched in IE, which I rarely use as I favor Firefox 3.5.
It looks like my IE (7.0) has been changed to use a proxy server on 127.0.0.1 on port 5555.
I'm typing this on my laptop which hasn't been infected.
There seems to be a variety of different solutions on these forums for this problem so I'm a bit at a loss as to how and where to start.
Any help in getting started is appreciated. Thank you.
