Smart Defrag Portable has been released. Smart Defrag is a powerful disk defragmenter with a fast engine and an easy to use interface. It's packaged in Format so it can easily integrate with the Platform. It's freeware for personal and business use.

Smart Defrag is a trademark of IOBit and is packaged for portable use with permission.

Update automatically or install from the portable app store in the Platform.

Story Topic:


Avast keeps telling me that SmartDefragPortable_5.7.0.1138.paf.exe has "Win32:Malware-gen" virus. It happened in 2 different computers, so I think it's not a virus from my PCs. Also, MD5 hash is the same, so I believe the exe file wasn't corrupted anyway.

I think it's a false alarm, but it's happening so many times! Is there anything I can do to avoid it?

(By the way, among newest installers, I had this or other problems downloading or installing CDex, Database Browser, Q-Eye and Smart Defrag. Each problem is commented on its program page.)

I'm not sure what's up with the Avast, AVG, Avira engines the last couple days, but they're having false positives quite a bit.

It also appears to be a very specific definitions update that's borked amongst those antivirus apps. 1 out of 39 shows a false positive on MetaDefender.!/results/file/ZTE3MTAwNUJKNGUyZm5DWGhicmt...

And if you happen to get a scan with yesterday's definitions, it's 100% clean:!/results/file/ZTE3MTAwNUJKNGUyZm5DWGhiUzE...

Sometimes, the impossible can become possible, if you're awesome!
