Adobe Trojan infection was reported to be found on systems installed with any of the latest Adobe CS4 trial versions of Photoshop ,Dreamweaver, InDesign and Illustrator.

Reported cases:

“I downloaded trial versions of InDesign, Illustrator and Dreamweaver direct from adobe.com last week, installed them, but kept the install files for future reference. Then this evening I get multiple virus warnings, alerting me to the presence of the Crypt.CFR trojan in all the setup.exe files.
There’s no mention of Crypt.CFR anywhere on the internet, as far as I can see, and no mention of false positives with recent Adobe products – just the cracked Photoshop CS4 and the Flash thing from last year. I find it hard to believe that there are new trojans in official CS4 downloads, but it’s strange that no-one else is reporting this. I’m on 8.0.176, with virus pack 270.10.14/1917. Anyone had similar issues? I’m on a brand new computer and haven’t got the hang of Vista yet, so am unable to upload the setup.exe files to jotti or virustotal – keeps telling me I’m not allowed!” –EthylMormon from Avg forums

“The same thing happened to me this morning, AVG said it’s a Trojan from the Adobe Dreamweaver installer, but I don’t think it came from Adobe, I’ve had this on my machine for over a month without a problem. I removed Dreamweaver after putting the Trojan into the virus vault and about 10 mins later it turned up attached to something else. I know Adobe can be very invasive, that’s down to aggressive marketing on their part but I don’t believe an organization of their reputation would knowingly deliver malware. It is strange though that it only being reported today”- Cliff from Yahoo Answers

“I’m pretty sure this is a false positive, and sorry for posting about it here, I don’t know where else do go. The setup of the support forums is confusing me.
Anyway, AVG Free detected a "Trojan horse Crypt.CFR" in Common Files/Adobe/Installer/and a bunch of numbers and letters/Setup.exe . From what I’ve read, there is no such thing as a "Trojan horse Crypt.CFR" and that this is probaby a false positive, but just to be on the safe side, I wonder if anyone else has experienced this and knows what to do.” –Aeolian from Adobe Forums

Update:As expected,it was a false positive from AVG and “trojan warning” of Adobe installer has been removed in the last definition update.

    I had the same with an original installer DVD from InCopy CS4 and AVG Network Edition 8. I had to disable the resident shield before i could install the program.
