Thanks for reporting back, curiouser and curiouser. My computer is running sort of “funny” the last few days, did Avast check, nothing wrong..
I need a tech guy to have on hand!
run a malware check - we are being visiting plenty of strange sites these days...
www.superantispyware.com
free (not the red box free trial, the yellow box plain ol FREE)
first get your updates, then run a quick scan - delete everything it finds. Reboot. Run it again, a full scan.
I also use www.malwarebytes.com. free.
