I did an online scan at Panda and it found adware/ist.istbar. But it wasn't det. by Kas, NAV, Ad-aware, S/D, Microsoft Anti-spyware. Location is C:\Prog. Files\Common Files\Totem Shared\update I found files with Advertising & Distribution & Free Samples as file names but there are files with Network, System, Update, Windows names also. Common to all these files is the ext. .dll with a number after it e.g. Advertising.dll.043, FreeSamples.dll.042, Windows.dll.049 etc. Is this a legit folder in xp? 'cuz I have encountered other .dll ext. from legit programs and they don't have the number after it. I'm holding off in deleting the folder for now. Do some snooping around for info. Any comment is appreciated. Thanks.
