Ive recently recoverd from a bad spout of virus / spyware. But still have one last problem lurking. When i do a thorough virus scan with AVG it finds no traces of a virus or trojan. But now and again ill get this popup window. http://www.puce123.force9.co.uk/images/misc/purityscan.gif Ive run all the of standard spyware scanners, CWShredder etc but cant get rid of it. Any ideas?
