Anchor.Hss - spyware?

Hello, I scanned my computer, and  Spybot has detected spyware Anchor.HSS every time I used it. It belongs   to: PUPSC - it stands for potentionally unwanted program.

By searching for .hss on google, I found out .hss belongs to Adobe.

I  use other programs to detect malware/virus/spyware/adaware as well.  Programs are Spybot SD2, Malwarebytes, Advanced SystemCare 6, IOBit  MalwareFighter, AVG, Super AntiSpyware. Only Spybot SD (1 - the old one)  has detected the same problem again and again.

Every time I  decide to scan my computer, I go to safe mod, since it is able to catch  more unwanted stuff in my PC. Only spyware I have ever had problem  removing was this one.

I looked at malware removal guide - Anchor.Hss thread here:

http://forums.spybot.info/showthread...for-Anchor-Hss but none of what  was mentioned there I found anywhere on my PC. I checked regedit, I  checked appdata,etc.

Not sure where can I located sysdir though, is it basically system32 folder? I checked that one, nothing there either.

Spyware still keeps coming back :/.

Any suggestions please? Is Anchor.Hss harmless or harmful? Does it actually belong to you?

I   have noticed Adobe Acrobat among addons in Firefox, I think it asked me  for update few days ago, I declined it, and I can still see it asking  for update among Firefox Addons.

Thanks.
