Malware warning for PortableApps.com on Google, Firefox, Norton 360

Firefox reported it too although if I ask for why, it sends me to a page that says no malware has been found in the last 90 days. I hope this solves itsself quickly.

I've confirmed that this seems to be Google-related, by searching "portable apps" in Safari on the iPhone & clicking on the PA.c link in the search results. The following page pops up, and has a google URL:

Looks like John needs to request a review using Google's Webmaster Tools.

There was a security issue in Drupal that was patched yesterday, but we didn't get the release notification from Durpal.org for some reason. Someone attempted to perform a JS injection attack on the site some time this AM (which failed). However, the inserted bits were detected as possibly malicious. As the file that was attempted to be infected isn't needed by our current theme anyway, the file was removed entirely (which should speed up the review). Yesterday's Drupal patch was fully applied and verified.

Google has been notified and a review has been requested to remove the warning. Note that during this time, no infected files were served and no malware was inserted.

According to Symantec, the issue with Norton 360 has been resolved. Could someone using this (like the original poster darkness2fall) please verify this?

Ahhhh you guys are fast. Knew it has something to do with the Safebrowsing thingy though I didn't know it had something to do with Drupal

Don't know if it's relevant but I maintain a few small apps created with AutoIt. The AU3 compiler compresses executables with UPX by default, and I was getting numerous false malware positives. Removing UPX compression solved the problem. I guess we have to accept that compressing executables makes AV software suspicious.
