Why MSE doesn't remove an infected file from inside a compressed/rar file?
After more than a year using MSE, I found it good to protect my PC, but one thing I didn't like that MSE doesn't remove an infected file from inside a compressed/rar file that contains documents and photos, and what MSE does is quarantining the whole zipped/rar
file instead of removing only infected files from inside it.
An example of what I experience:
When I download a zipped file to my desktop and browse it with winrar, and see the file contains documents, photos and an infected (eg. exe) file, and then when I scan the zipped file by right click (after closing winrar), MSE shows the detection of the infected
exe file. I choose to Remove for the specified item and then apply action. After the removal process show as Succeeded, I found the zipped file is removed from my desktop and I found it in MSE Quarantined items (since I didn't choose to quarantine!). However,
when I restore the zipped file and browse it again with winrar, I found nothing changed, my documents are in the file but the infected exe file still exits in it, which means MSE didn't remove the infected file, but it has quarantined the whole zipped file
with its contents when I choosed to remove the infected file in it.
So when I want to have a clean zipped file, I need to extract it then scan and clean the extracted folder, and then compress it again, and delete the original one.
So the question: Why should I extract a zipped/rar file (to remove an infection) scan and clean it then compress it again?
In other words, why MSE doesn't remove an infected file from inside a compressed/rar file without extracting anything?
