I'm in a bit of a bind, and any help would be more than appreciated.
Some number of weeks ago, my computer became infected with something (I was never able to figure out exactly what the issue/virus/malware etc. wars). As a result, I was unable to use Google Chrome (my default browser) or Internet Explorer 7, so I reverted back to Mozilla Firefox. This was more of an inconvenience than a problem, as some programs didn't run perfectly anymore (e.g. I couldn't acces my hotmail inbox directly from MSN anymore), and if I clicked IE 7 accidentally, it would take a VERY long time to close.
Anyways, a few days ago my computer became infect with malware, and I have not been able to run anything because the fake antivirus program AV Security Suite will not allow me to. Originally, I couldn't not run anything, but then, without any reason, I was able to run Firefox again. I went to this site
and downloaded the Spyware Doctor, which AV Security Suite would not allow to run. So I installed it by booting my computer in Safe Mode with Networking. However, when I was finished, I was told that the Spyware Doctor needed updates to run, so I selected the option to download updates. However, I was unable to download them and the program closed, I'm assuming because of the aforementioned internet issue: my computer has trouble doing rudimentary things because it does can't run through IE anymore, because it doesn't work. (Also its not helping that without any provocation, IE is opening randomly to links to porn sites, which is a pain, given that it stays open for a long time).
As a result, I'm at an impasse, and am in need of some help. Again, any help would be more than appreciated.
If it helps, I am running Windows XP Professional on a Dell Dimension 3100.
