ScanIn addition to the background scanning process performed by the
Anti-Malware module, KIS provides a set of customizable scanning tasks. For instance, they can be used to perform the scanning process at specified times or on selected file types only.
Scan: a generic customizable scan task. You can also use this task to define global scan settings for all the tasks. To do so, click on the
Apply button in the
Other task settings section.
Full scan: a complete scan of your pc (system memory, start-up objects, system backup storage, hard and removable drives etc.).
Quick scan: a quick scan of system memory, start-up objects and disk boot sectors.
For each scanning task, you can specify the preset
Security level and the default action to be performed when an infected or potentially infected object is detected.
Security level: you can choose between
High,
Recommended and
Low. The higher the level is, the more thorough (and long) the scan will be.
On detection: specify the default action to be performed when an infected or potentially infected object is detected. You can choose between
Prompt on completion (at the end of the scanning process, KIS will prompt you for the action to be taken on any detected threats),
Prompt for action (you will be prompted for action during the scan, as the threats are detected) and
Do not prompt (KIS will automatically take an action on the event according to the current settings).
Selecting the
Do not prompt item, will bring up some additional options:
Disinfect (KIS will try to repair the infected object),
Delete (KIS will delete the infected object), or neither of them (KIS will only
inform you about the threat).
When the
Disinfect action is set as default, the
Delete option will turn into
Delete if disinfection fails: in this case you can select both the actions.
If you previously checked the
Select action automatically box in the
Protection section, then the
On detection value will be set to
Select action automatically.
Run mode: select the run mode for the current scan task. You can choose between
Manually (the task will be run on demand) or
Every… (the task will be run at specified times or time intervals or under certain conditions, according to the options you set in the
Run mode tab of the task settings).
Click on the
Restore... button to restore the default settings.
Click on the
Settings... button to open the settings panel for the current task.
Task settings window ->
Scope tab
File typesHere you can specify which file formats should be scanned.
All files: all files will be scanned without exceptions.
Files scanned by format: only files which format can be infected will be scanned (for instance,
.txt files will be skipped). The format of each file will be determined by the analysis of its header information.
Files scanned by extension: only files which format can be infected will be scanned, but in this case the format will be determined on the base of the file extension (
.doc,
.exe, etc).
Warning: an infected file with changed extension (for instance, a
virus.exe file renamed as
virus.txt) will be skipped.
Scan optimizationScan only new and changed files: only the new files or the files changed after the last scan will be analyzed.
Stop scan if it takes longer than…: if the duration of the scanning process for a single object will exceed the specified time limit, the file scan will stop.
Scan of compound filesScan all/new archives:
all the
.arj,
.cab,
.ice,
.jar,
.lha,
.rar and
.zip archives (or only the
new ones) will be unpacked and scanned.
Scan all/new installation packages:
all the self-extracting installation archives (or only the
new ones) will be unpacked and scanned.
Scan all/new embedded OLE object:
all the objects embedded in files (or only the
new ones), for instance the MS Excel objects embedded in MS Word files, will be scanned.
Parse email formats: if this box is checked, then KIS will parse and scan the e-mail format files and databases, otherwise any e-mail files will be treated as single objects.
Scan password-protected archives: password-protected archives will be scanned (you will be prompted to enter the required password).
Click on the
Additional... button to access some additional settings.
Additional settings
Size limitDo not unpack compound files larger than: archives larger than the specified size will not be unpacked.

Additional tab
Scan methodsHere you can specify the scan method to be used for analyzing files.
Signature analysis: this is the standard scan method. KIS will compare the bit patterns of each file against a database of known virus signatures.
Heuristic analysis: the files will be virtually processed by a software emulator and monitored for suspicious activities. The heuristic method is useful to detect any unknown viruses before they have been included in the virus database. When the heuristic analysis is enabled, you can also set the level of analysis detail (
Light scan,
Medium scan and
Deep scan). The deeper the detail is, the longer the duration of the scan will be.
Signature scan of vulnerabilities: all applications will be checked for vulnerabilities against an updatable database of known vulnerabilities provided by Secunia.
Rootkit scan: the computer will be scanned for rootkits. Rootkits are hidden programs intended to hide something else: network connections, malware, registry keys etc.
Deep scan: turns on/off the deep scan for rootkits.
Scan technologiesiSwift and
iChecker are proprietary scan technologies developed to reduce the duration of the scanning process.
iSwift: iSwift technology is based on the comparison results of object IDs under the NTFS file system.
iChecker: iChecker technology is based on the checksum (unique digital signature) comparison results. On the first scan, checksums are calculated for all files. During the next scans, KIS will exclude certain files from scanning, through comparing the actual checksums with the saved ones.
Both iChecker and iSwift use a complex algorithm that involves many different variables (like, for instance, the release date of the program database, the last scan date and any modifications made to the scan settings).
Task settings window ->
Run mode tab
ScheduleSelect the run mode for the current scan task. You can choose between
Manually (the task will be run on demand) or
By schedule.
By creating a schedule for scan task, you can specify how often you want the task to be run. The task can be run at specified times or time intervals or under certain conditions (for instance, at application start-up or after every update).
Run skipped tasks: when this box is checked, even if for some reasons the scheduled task cannot be run at the specified time, then it will be run later.
User accountRun task as: check this box to run the task under a different Windows account.
