A recent scan of my laptop with a2 anti-virus threw up a high risk Trojan-Dropper Delf!IK in C:\Windows\Installer\244cc9.msi. However, no other scan (Norton 360, SUPERantispyware, Adaware, Spybot S&D or MalWarebyte have picked it up. I've tried uploading the file to Virus Total for a check there, but cannot find the file location when browsing my laptop. A search on Google for 244cc9.msi doesn't throw up any results.
Thanks for that, buteman. a2 seems a bit prone to false +ves. It threw up another on the same scan, Trojan.HTML.Pcard!IK which I uploaded to Virus Total (it was a large file) for a scan. After about three hours four applications had scanned it and found it OK and I then had to shutdown, so I assume that was another false +ve.
A Squared normally works Ok with other Anti-Virus programs installed.it has used Anti-Malware with Anti-Virus for a year or so Not sure if this new version is different or not. I would imagine anyone using a Squared would Automatically have been updated to the new version.But something to think about.
If A Squared has not reinstalled it yet. Maybe install it again from Quarantine.Reboot and see if Windows Installer works again. Update A Squared and run it and see if it finds the same problem again.If not you know it must have been a false positive.
