I've had similar issues with recovery tools. For example, the tool "Magical Jelly Bean Keyfinder" retrieves the product keys for some installed software such as Windows and Microsoft Office. It is quite easy to replace the installation media, but not always so for replacement product keys, especially Microsoft products.
With a quick test using the online scanner "VirusTotal", it checked this tool against 41 scanners and the results showed AntiVir, eSafe and McAfee reporting an infection.
My own AntiVirus Eset NOD32 is also quite picky and annoying at times and I'm most likely going to change AV once my subscription is up.
For example, have you ever heard of any problems with ExactAudioCopy?
Well, this is what Nod32 thinks of ExactAudioCopy (0.99 Prebeta 5) from the official exactaudiocopy.de website: :rolleyes:
I e-mailed Eset about this and they came back claiming it contains adware. But after downloading and installing this with Nod32 temporarily disabled, I never encountered any unexpected advertising.
Here's another "coincidence": Each time I try downloading the full installation of AVG Free edition on my PC, it always fails at 99% complete (at least with my 5 attempts in Firefox) with Firefox reporting that the source file could not be read. But, when I temporarily disabled Nod32, it downloads fine... I'm not aware of anything else I've downloaded where this happened.
