I received a call from someone at phone number 704-325-9111 - asked me to run DOS CMD ASSOC, verify send to target {xxxx} at bottom of page, then asked me to run DOS CMD EVENTVWR, said all the warnings/errors indicated that my computer was trying to 'download malicious sw', and that I needed to fix it and he would walk me through the process. As I did not initiate call, I was not inclined to proceed any further. Asked for a phone number to call back, he gave me 704-325-9120 for windows technician, I called that today - not in service. Called the 9111 extension back - said the person at that number was unavailable He also gave me url www. applet.com. Went there - said enter username / pw but warned that it was being sent using basic authentication over unsecure connection.
What does this all mean, what should I do.
