HELP! Lost Internet Connectivity

I installed CA Antivirus for my father last night on his Win98 Dell. 

 

The instructions he printed said to remove anything related to antivirus before running the executable for the CA AV.  I did not notice but it said on the CA website not to remove any EZTrust  (former name of same program - CA Antivirus).

 

The directions he printed for me, on closer inspection, were incomplete and had words missing on the side of the page that were not included in the printout.  So, they (EZTrust files) were completely uninstalled plus some old Symantec files as well.

 

I then installed the CA Antivirus but when I tried to download the new AV updates - I found that we had lost our connection to the internet completely.  We spent several hours with Verizon DSL Tech Support and they can find nothing wrong with the account status and spent a while doing line checks.  He said everything looked fine from their end - but we just can't get their modem to pick up the signal.  Their supplied modem just cycles every so often to establish a connection with our PC but to no avail.

 

I went to CA AV tech support and typed a description - like this one - and they popped a window open with something (a file I think) to "RUN" - but I'm doing this on my home PC and not his, so it doesn't do any good to try to get him help in this manner, as he can't access the few fixes I've found like LSP Repair file or the downloads from CA AV regarding the problem.

 

I am posting here since he's 87 and just can't handle it anymore.  I'm hoping someone might kindly share any insight or possible fixes we can do on his PC w/o an internet connection.  He can't afford to take it to a PC shop and have it repaired.

 

Sorrry for the lengthy post - please help us if you can?

 

Best Regards,
