A couple of days ago I downloaded SD5. It have http://spyros.atspace.com/ bookmarked. SD5 detected it as a high threat. I didn’t have the page opened at any time while SD5 was on my computer. spyros.atspace.com is Spyros’s website. Spyros is a respected member of avast! forums and I don’t believe he would have a site that has malware & phishing. No other infection was found.
Also, SD5 froze Opera & my computer in cycles. It would freeze Opera, then free it. Then it freeze my whole computer, then free it.
SD5 may treat all of atspace.com as high threat/risk, (including sub domains) since atspace.com has come in for some stick previously.
I have to admit I have never heard of SD5 before this post, unless your are abbreviating version 5 of some application and google doesn’t throw up anything useful.
