Automatic virus checks
You can switch the idle scan on or off from here. Furthermore you can also regularly scan your computer, or areas of your computer, for infections instead or as well. For example, you can then run such scans at times when you are not using your computer.
Scheduled virus checks: In many cases it is sufficient for the computer to be checked by the idle scan. However, you can also use the New button to set up various automatic virus checks that are independent of one another. Hence it is possible for you to check the Downloads folder daily, whereas you check your MP3 collection only once a month for example.
The following sections explain how you set up individual virus checks.
Automatic virus check - General
Enter the name you want to give the newly created virus check here. It is a good idea to use meaningful names to differentiate between the various jobs, for instance, Local hard disks (weekly scan) or Archive (monthly scan).
If you check Switch off the computer when the job is finished, the computer will automatically shut down once the automatic virus check has been completed. This is useful if for example you want to run a virus check when your day at work has finished.
Here you can choose whether the virus check should be done on the local hard drives, whether memory and autostart areas should be tested, or if you only want to test certain directories and files. If this is the case, use the Selection button to specify the directories you want.
Check following directories and files: In the directory tree, you can open and select directories by clicking on the plus symbols. Their contents will then be shown in the file view. Each directory or file that you mark with a check will be scanned by the software. If not all files in a directory are checked, this directory is marked with a grey checkmark.
Automatic virus check - Scheduling
This tab allows you to specify when the automatic update should run and how often. You set up the default schedule under Run and then specify it in more detail under Time. Of course, if you select On system start-up, you need not set any scheduling as the software will run the scan each time your computer starts up.
- Run job automatically on next system startup if systems was powered off at the scheduled start time: Activating this option means that virus checks that are not run automatically are automatically run later as soon as the computer is powered up again.
- Do not run on batteries: To prevent limiting battery service life unnecessarily, you can specify for notebooks, for example, that automatic virus checks can only be run when the portable computer is connected to the mains.
This area allows you to define which settings should be used for the automatic virus check.
- Use engines: The software works with two engines – two virus checking programs optimized for one another. You can accelerate the virus check in older and slower computers by using just one engine, but normally you should keep the setting Both engines.
- Infected files: Has your software detected a virus? In the standard setting, the software now asks you what you would like to do with the infected file. If you would always like to perform the same action, you can set this here. The highest protection for your data is offered here by the setting Disinfect and copy to quarantine.
- Infected archive: Here you determine whether archive files (e.g. files with the extension RAR, ZIP or PST) should be handled differently from normal files. However, please note that moving an archive to quarantine can damage it so that it can no longer be used after it is moved back.
Furthermore, you can click the button ADVANCED to specify which additional virus checks should be performed or omitted.
In most cases, however, it is completely sufficient to use the specified default settings.
- File types: You can specify here which file types should be inspected by the software for viruses.
- Heuristics: In the heuristic analysis, viruses are not only detected by the virus database, which you receive with every update of the software, but are also identified on the basis of particular characteristics typical of viruses. This method increases the level of security, but in rare cases may generate false alarms.
- Check archive: Checking compressed data in archives (these can be recognized by their file extensions such as ZIP, RAR or PST) is very time-consuming and can normally be omitted if the virus monitor is generally active on the system. The monitor can detect a previously hidden virus while the archive is being unzipped and can automatically prevent it from spreading.
- Check email archives: Here you can specify whether your email archive is examined for infections as well.
- Check system areas: In general, system areas (e.g. boot sectors) in your computer should not be excluded from virus checks.
- Check for diallers / spyware / adware / riskware: You can also use this function to check your system for dialers and other malware (spyware, adware and riskware). These are e.g. programs that establish expensive, unwanted Internet connections, of which the potential for financial damage is no less significant than that of the virus. They may for example secretly record your surfing habits or even all the keyboard entries you make (including your passwords) and forward these to third parties via the Internet at the earliest opportunity.
- Check for rootkits: Rootkits attempt to evade conventional virus detection methods. Additional monitoring for this malware is always advisable.
- Generate log: By checking this box, you can specify that the software creates a log of the virus check process. This log can be viewed in the Logs area.
Here you can specify the user account on the computer on which the virus check should take place. This account is required for access to network drives.
