I will try to copy & paste my link here - but I am afraid I may lose this post in the process.
grc Link: #703885 Nothing caught this one. And nothing seems able to remove it. Not SpywareBlaster, not Spybot S&D, not SpywareDoctor, not AdAware, not my Yahoo! AntiSpy that comes with my ISP contract. I update these protections several times a week (I'd say every other day) at least. Yahoo! AntiSpy will catch it when I scan, but after I click "Remove", it just comes back (and apparently Yahoo! AntiSpy has no Quarantine feature). It ("Netzip") prevents me from executing Administrator actions. I have (somehow) eliminated (removed) the program I think that it came from ("Speed Optimizer"), but everytime I attempt to Logon as administrator, it restarts my system. CleanUp is of no help either. I have tried everything I know - for several days now - to no avail.
Can anyone help? Yahoo! identifies it as "Netzip" and as "Spyware". Also, this vermin seems to have cut-off my ability to update programs/protections.
