In short, I was visiting my usual places on the 'net this weekend when an error message popped up, "Beware, a Trojan virus has infected your computer. Warning, your computer has been compromised," etc. I called my ISP which also provides my anti-virus protection, for which I pay, and apparently tech is not open on the weekends. I called HP, I'm still under warranty, and over a three-hour period decided to let them guide me through setting my computer back to factory settings (my important documents are backed up). What is my ISP responsible for? I always update my anti-virus protection, and I certainly pay for it every month, but what if my computer were destroyed? At most, I don't want to continue with *their* anti-virus software, but I'm under warranty. Any suggestions on what I should say when I call them?
