Title: question about the effects of chkdsk command on removed viruses
Post by: :o on December 15, 2018, 09:33:23 AM

when avast removes a virus (or worm or trojan or rootkit might be wrong though) it "encrypts" (an action im too stupid to understand) it in the disc "killing" the virus but it remains on the disc.

my question is: can chkdsk or one of its parameters restore/repair an unwanted virus unintentionly?

No.

Chkdsk is really just about correcting system indexing errors, identifying weak sectors of the HDD, writing anything there somewhere else and marking the weak sector as not for use. That's about all it does.

It should repair any faults in the system indexing caused by malware but it isn't going to re-activate deleted malware itself.

Doing something like that sounds like the sort of bad idea a book author or screenplay writer might use as a plot device for re-infecting a computer or network. :)

Chkdsk cannot perform this action but a malware author could play on user fears for phishing purposes (or similar).
