Windows 10: Files not opening during virus scan

When performing a virus scan with ESET there are many files that are not opening during the virus scan. Why is that and how can I open them?Such as: Log C:\DumpStack.log.tmp - unable to open [4] Log C:\Program Files x86\Microsoft Office\root\Flattener\AppvIsvStream32.dll - unable to open [4] Log C:\Program Files x86\Microsoft Office\root\VFS\ProgramFilesCommonX64\Microsoft Shared\OFFICE16\AppvIsvStream64.dll - unable to open [4]

Windows Security Virus Scan

Please confirm you don't have a list like this:




e.g. from here (or via the control panel):




If not, suggests deeper problems. To which uninstall option are you referring? (A picture is worth...)

 

Virus Scan ONLY tool?

I was using Malwarebytes to run scans on things I downloaded to make sure they're clean before I run them... but now Malwarebytes wants to run constantly and wants to do virus scans all the time, even though I told it not to (I'll scan a single file then it starts another threat scan on its own).

Are there any good tools that do virus scanning only?

 

Files not opening during virus scan

"Object is locked skipped", "File locked", "Locked file. Not tested", "file cannot be accessed, "Access Denied", "Some files could not be scanned", "file could not be opened", "Error Opening",
"unable to open", "Password Protected" or "Encrypted" notations in an anti-virus or anti-malware scan are not uncommon.

Some files and services are locked by the operating system or running programs during use
for protection, so security scanners may encounter problems attempting to access them. Other legitimate files, especially those used by security programs, may be
obfuscated, encrypted or password protected in order to conceal itself so they do not allow access as a protective measure. When the scanner finds such an object, it makes a note and then just skips to the
next one. That explains why it may show with such notations but no action taken in certain anti-virus or anti-malware log scan reports. These are normal when using security scanning programs so there is seldom a need for concern.

• Why can't my anti-virus program open certain files?
• ESET: Error notifications in Computer scan log
• Bitdefender: Password protected items
• avast! How do I handle files that Avast can’t scan?
• Antivirus scanner cannot read/scan some files

Note: It is also not unusual for an anti-virus or anti-malware scanner to have problems with or be suspicious of

compressed,
archived,
.cab,
.rar,
.jar,
.iso, and
packed files because they have difficulty reading what is inside them. These kind of files often trigger alerts by security software using

heuristic detection because they are resistant to scanning (difficult to read). This resistance may also result in some scanners to stall (hang) on these particular types of files or just ignore (skip) them.
