Macro virus on macOS Sonoma 14.3.1

I think I have a macro virus on my macOS Sonoma 14.3.1; My keyboard doesn't work on the following letters:

u, i, o, j, k, l, m, 7, 8, 9 and the period, also when " I" is capitalized, it highlights the sentence and will sometimes jump to another line. It appears on any typing program on my main iMac .

Any help would be appreciated! I have tried My Norton360, but it doesn't see a problem; I have tried MicrosoftDEFENDER, and CLEANMyMacX - they don't see a problem.
