"last scan" results strategy - which option to choose?

consider the attached… i have 4 options: “delete,” “move,” “chest” and “scan.” when - and where - to move, when to delete, when to move to chest, and when to scan?

Into Chest (Quarantine) files are safe and can’t harm your computer.
If you way some days and rescan a file and be sure it’s not a false positive, you can delete it.

Here, in your scan results, you shoud consider which file are you talking about.
Repair > Send to Chest > Move/Rename are sequencial options.
Last option would be delete as you won’t be able to restore the file in anyway.

how can i verify, say 50, files? or 600 files?!! clearly, there must be a reason why i would verify a false positive - what are possible reasons?

while i respect your answers, let me say - and respectfully - that your English is not good: i cannot understand this answer.

From your image there are two important points:

  1. The files in the image are reported as ‘Unable to scan’ (not infected) there should be a reason given.

Many programs (usually security based ones) password protect their files for legitimate reasons such as AdAware and Spybot Search & Destroy, there are others (and avast doesn’t know the password or have any way of using it even if it did know it). This would seem to be many of yours Unable to scan: Ar…, the … means more text and this is probably Archive is password protected.

When you run scans with the above programs and you delete harmful entries that they detect, a copy is kept (in quarantine/restore/backup) in case you need to reverse what you did. These are usually password protected, you should do some housekeeping and delete old backup/recovery/quarantine entries (older than two weeks or so), this will reduce the numbers of files that can’t be scanned.

By examining 1) the reason given by avast! for not being able to scan the files, 2) the location of the files, you can get an idea of what program they relate to. You may need to expand the column headings to see all the text.

Files that can’t be scanned are just that, not an indication they are suspicious/infected, just unable to be scanned.

  1. The location is shown as C:\Windows.old\Users do you have two copies of windows or what is the relevance of the strange folder name Windows.old ?
    You will also notice that the path and some of the text is compacted .…\ or Text… this means that the data is larger than the column width (see image, drag the column separators to the right to see all the text)

Firstly Tech speaks the languages that I know of, English is not his native language and his English for the most part is very understandable.

The problem as I see it is a lack of detail in your question, you asked about four options and Tech simply gave you the order in which you should try them, unfortunately he hasn’t fully understood what you asked, had he done so I’m sure you would have got a similar answer to the one I just gave.

You have also created two almost identical topics about this issue (just duplicated effort for those helping), which Tech has answered very well in a similar way that I did. Some tact in your response to answers won’t upset those giving their free time to try and help you. All of those who are trying to help are avast users just like you we aren’t employed by Alwil, we are just trying to help other avast users.

do you have two copies of windows or what is the relevance of the strange folder name Windows.old ?
i did a vista reinstall. by default, and automatically, vista images the entire C:\ that's about to be deleted, and saves it as a file called windows.old - in my case, it was 12.0 GB

wrt to your following post, saying that i should use tact: i thought i did – i said “respectfully.” but the fact is that the english grammar was, from my perspective, almost unintelligible. what should i have said? it may be best, and next time this will be my strategy, to remain silent.

Then the sooner you get rid of that 12GB back-up which is obviously protected the sooner the unable to scan will be reduced. You could exclude the windows.old folder from scans, that would also reduce the unable to scan list, but to my mind could possibly leave a hole in your protection if anything could be created (malware, etc.) there if the protection isn’t also write protected for the folder.

Sorry but just tacking on respectfully doesn’t cut it, it is still a slight on someone who is genuinely trying to help do you think they would waste their time (or yours) helping if they didn’t think what they wrote genuinely helped. You didn’t find any fault in his other answer to your other post.

What would have been wrong in saying sorry but I don’t understand the answer and ask for clarification. No slight of a person there.

We don’t worry about grammar or spelling here as many of the forum members don’t have English as a first language, not only that they are writing in a foreign language and English grammar isn’t easy to grasp. The major issue was one that the question wasn’t understood so the answer won’t appear to make sense either.

i have tried several times, in this and other forums, to resolve an unintelligible response by pm (personal message). i felt that dirty laundry should not be publicly aired. and each time i was chastised, insisting that the dirty laundry indeed be aired in public. so that’s what i do! if that is what you insist on, then that is what i will do, even if it does contravene my sense of decorum, and offends me!

No one has suggested anything about using PMs or anything about dirty laundry, there is nothing here about that and this is hardly dirty laundry, you will see many topics in these forums that would be classed as dirty laundry by some and provided they don’t get personal aren’t taboo.

All I suggested was simply rephrasing your response leaving out the un-necessary comment and just say sorry but I don’t understand the answer and ask for clarification (as I mentioned before and you quoted), that is it.

When you say that you don’t think someone’s English isn’t good (when you clearly didn’t know anything of the persons background) and they are trying to help you, it is hardly likely that they will be prepared to try again, so it is also in your best interest.

Now, for me this has gone far enough and isn’t achieving anything. I’m just an avast user and forum member like you (and Tech) I have made a suggestion how you respond to that suggestion in the future is entirely up to you, so I’m done in this topic.

Please, don’t remain silent when I commit mistakes. Correct me.
But don’t post PM content here. David has rights to his privacy.
By the way, thanks David to ‘defend’ my English…

nweissma, post which files are you talking about (please, post the full path and the file name).

Repair should be the first option while scanning or working to files into Chest.
While scanning, if repairing fails, then try to send the file to Chest.
If if fails by any reason, try to move or rename the file.

Into Chest, the actions to be taken are more or less intuitive.
Extract means copy the file from Chest (protect folder) to another folder (unprotected) in your computer.
