I am reasonably sure I have removed the rogue program antispycheck 2.1 from a neighbours computer. I deleted all relevant folders, files and registry entries and used HJT to remove a few relevant odds and ends. I stopped aspch from running at start up. I uninstalled antispycheck 2.1 using Add/Remove programs. I ran another registry cleanup to make sure no references remained. I also removed 12 Downloader.Zlobs and a quantity of spies. Re-running anti virus and anti spy programs shows the computer is now clean.
However, I am unable to remove the live link to the antispycheck website which lives in the Windows XP notification area. It is a shield just like the Windows security shield, it flashes alternately from red to blue to red to blue. Making sure I was off-line I clicked the shield to see what URL it was linked to. This was antispychecker.com//?aid=1012
At regular intervals of about a minute the shield throws out one of two false warning balloons. The yellow triangle in the balloons looks quite genuine but the System alert asks you to either download antispyware or download a tool for removing malware. Something is also resetting the Windows automatic update to 'off'.
I would be grateful for advice on stopping this little blighter from operating.
