I have a Win98 machine 256 Meg 30 Gig HD ... I can get a connection to my ISP ... but I am pretty sure some trojan or spyware altered the settings for how IE communicates with the Internet... after fruitless attempts to fix it I downloaded Opera and that worked for a while.... then didn't ... after several months of inactivity (I have another computer I can use) I have downloaded Firefox ... but that would not work at all. All browsers basically give the same message that the URL is not obtainable. ..
Are there any sequential steps and tests that I can perform to identify, isolate and fix the source of the problem?
Thanks in advance for any help provided... Chris
