I am running Zonealarm internet security suite 9.3.037.000 with regular updates on a PC with Win XP SP2.
Yesterday I clicked on a folder on my desktop and I got a ZA popup that said that it had found Packed.Win32.Katusha.n and quarantined it. I was surprised that it said this was found in a McAfee rootkit detective program (Rootkit_Detective.exe) that I ran once about 3 years ago and is in a zip archive. When I ask for more information on it, the Kaspersky search says no matching records.
I saw today where there is another file quarantined by ZA, which is a system restore file. also tagged as having Packed.Win32.Katusha.n.
What should I do now. I still have the zipped archive of the file it alerted on, so should I send it into Kaspersky for analysis? Also, how do I get rid of all my old system restore points?
