http://support.pcsecurityshield.com/faq/FAQs.asp?c=89 I have been contacting these guys via email, phone calls and everything available to me. they use yogi, which is supposed to help them give customer support. so far the only thing yogi has done is kept me on the phone for 30 minutes.. twice. then transferred me to another line, which promptly hung up on me. the second time I called I told the guy he needs to stay on the phone with me until I was effectively transferred. he said ok, then transferred me to a line which dropped me, just like my previous call. I even gave the guy my email address, he stated he would have the link sent to me directly. it never happened. Oh btw their "support" is in india. So good luck with that.. They won't even respond to my emails, even though their supports says 24 hours for a response. I just installed win 7 x64 and now for 3 days I have no antivirus.. I'd stay away from these guys like the plague. I See MBAM has an active protection now a days. They never failed me before. I think I'll go with them. Honestly the pc security shield and the deluxe shield, never once caught a virus on my pc. I have used them for 3 years. I have had dozens of viruses since I got them, all of which have been caught and removed by Mbam. Not A SINGLE VIRUS has ever been caught by this crappy ass software. don't get it, it's useless and their customer support ignores you.
