Keep hitting issues for months cant fix it easily!

[MichioEmoto]

Okay so I know my getac b300g5 is way outdated in some ways.  I have been getting continuously hacked for a few months and this time apparently theres a decompression bomb which makes sense since sometimes my laptop crashes or slows to the point of not being usable.  Ive done chkdsk C: /f, detailed scans, and boot scans.  it seems boot scans are the only thing that catches the alterations which are typically found in the windows delivery optimization cache and is usually error 42125 but this time i got error 42110 as well which is noted in the boot scan results notepad view.  I have tried deleting the containing folder, searching for ways to fix and prevent this and I am at the point of looking for computers to buy that are new and run mac os.  heres the results:

Please let me know what the best course of action is to repair and prevent this from happening if it is a threat

These errors are just that, an error, a file that can't be scanned, not an indication that they are infected.

If a zip archive is corrupt there is no way Avast can fix that.  If the program that created the zip archive were to be able extract the contents of that archive then Avasts resident on access scanner would scan the extracted files (according to your settings).

As for the - Decompression Bomb, a file that is highly compressed, which could be very large when decompressed. This used to be a tactic long ago to swamp the system.

The name really is the most dangerous thing about this and I wish they would change it or simply not report it, a real PITA.

These highly compressed files are generally 'archive' files which are inert, don't present an immediate risk until they are unpacked. If you happen to select 'All packers' in your on-demand scans then you are more likely to come across this type of thing. Personally it is a waste of time scanning 'all packers' and that is why it isn't enabled by default.

Thanks for the reply.  I have actually read the decompression quote you posted already and because it is from 2016 and my laptop is from around then, it doesnt bring me much confidence as the laptop is the same with old hardware that can easily be exploited and it is 5 years later.  It seems logical that then someone who could exploit my vulnerabilities may do a form of testing my knowledge by slowly increasing the quality of exploits.  The piece that makes it seem logical is that there are a few people spearfishing me over the past few months and have admitted to it on some occasions and then others i log all the details while allowing the individual to blatantly shoulder surf, social engineer, and play with what they think is my level of understanding.  While they figure out how "good" I and my network are they may use the oldest least powerful or harmful tools and see what I do.  I have had many accounts hacked in which I allowed it to create a trail of obvious attempts in case THEY are not as good as they think, like tai chi my body moves with theirs connected and controlling the majority of the flow of energy until it is the right time.  That being said, I ran chkdsk C: /f and recall something like a keylogger also being in there somewhere. can you help with the chkdsc scan results if I post them by chance?

The post, was probably also mine and the situation hasn't changed, we really are talking about ancient history when decompression bombs could bring systems to their knees.

A 2016 era laptop is by comparison, like a main frame computer from the era of compression bombs.

Sorry, I can't really help with the chkdsc scan results.
