My mother emailed me this morning asking about some behavior she had seen when entering a credit card number on a shopping site - she said that the numbers she entered were turning into lower case letters on-screen.
She has Avast free installed, and has scanned which has come up clean. I advised her to do an additional scan with Malwarebytes Anti-Malware.
I'm wondering if any of the keylogger protection in the Avast web plugin might cause this kind of thing? She's running Chrome.
Apologies, I can't do much scrutinizing as we're in different countries, but thought I'd ask on here if anyone has seen similar behavior?
Thanks
