boot scan error 42125: corrupted compressed files

Hi there, recently I've been running a boot scan and I'm encountering a lot of 42125 errors ("corrupted" compressed files).

In order to solve it I downloaded a third part software (DiskInternals ZIP Repair) and manually "fixed" some corrupted compressed files but to no avail, cause the next time I ran the boot-scan the problem reappeared.

Could you help me solve this? Could my files be "healthy" anyway or they are corrupted for sure?


Thanks for your attention


Kind Regards

Thank you for sharing the screenshot, Norberto.

We'd like to inform you that few zipped files might be unavailable to scan at boot time, which might produce this error.
We assure you that these are not threats, they're just unavailable to be scanned at boot up.
Let us know if you have further queries.

Hi, thank you for your answer, I understand what you said, I hope I'm not going off-topic including an additional issue I came across while reading another log
User-added image
This time it's a full system scan. I noticed those 42110 and 42006 errors, respectively "Decompression Bomb" and "File not available" it seems. Does the first one mean AVG is having a hard time again trying to decompress? Are there any actions I should take?

Thank you in advance!

We understand your concern, Norberto.

A ‘ Decompression bomb’ is a term given to archived file (RAR or ZIP) that has a very high compression ratio. These files have the potential to grow to be very big once they are extracted and possibly use up all the memory.
This is not necessarily a virus. If the contents are unpacked, the AVG file shield will scan them for any malicious content.

Recently I am working with Magnotek (https://www.magnotek.cl). My computer often suffer from viruses I have tried a lot of anti virus programs but still something goes wrong. Even one time my Kazan every aniti virus failed to remove malware at that time I removed malware in safe mode. Now I have a lot of information about that.
