Same for me, ive just registered so I can comment on here...
Last night same issues with 90% of my Portable Apps...
7Zip, Handbrake, Firefox, MediaInfo, Fotografix... all seen as malware.... I actually removed them first but I had the same versions for over a year and never a problem with them so I know they are fine... Just Suddenly detected as malware[at] (#3i0uplmysdze7) that's the most common one...
Latest update 10.2.0.6526 / DB 28948 /Website DB 22061
Hopefully we can get this sorted soon, thx
