Monitor - Advanced settings
Furthermore, you can click the button ADVANCED to specify which additional tests should be performed by the virus monitor.
Normally you do not have to change any settings here.
- Mode: Here you can specify whether files should be checked when run, when read or when written to and read. If a file is checked when written to, the check is carried out as soon as a new file or file version is created to see if an unknown process may have infected this file. Otherwise files are only checked when they are read by programs.
- Monitor critical folders in particular: You can use this function to specifically check especially critical folders, e.g. folders shared on the network, personal data or Cloud services (such as Microsoft Dropbox, OneDrive, Google Drive etc). After you have made your selection in the dialogue box, this is then always monitored in Check read & write access mode – regardless of the settings you use for all other files, folders and directories. If you have selected the Check read & write access mode for all files by default, the settings option for critical folders is greyed out.
- Check network access: If your computer has a network connection to unprotected computers (for example, other laptops), it is a good idea to check the network accesses to see if any malicious programs are being transferred. If you use your computer as a stand-alone computer without network access, you don't need to enable this option. If you have installed virus protection on each computer in the network, it is recommended that you turn off this option. Otherwise, some files will be checked twice, which negatively affects speed.
- Heuristics: In the heuristical analysis, viruses are not only detected by means of virus updates that you regularly receive from us online, but are also identified on the basis of certain 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. To increase the speed of the virus check, you can limit the size of the archive files that are browsed to a specific value in kilobytes.
- Check email archives: Because the software already checks incoming and outgoing emails for virus infections, it is usually a good idea to omit regular checks of email archives since this process may take several minutes, depending on the size of the mail archive.
- Check system areas during system start: In general, system areas (e.g. boot sectors) in your computer should not be excluded from virus checks. You can specify here whether you want to run a check on system start-up or when media is changed (for example, a new CD-ROM). Generally you should have at least one of these two functions activated.
- Check system areas during change of medium: In general, system areas (e.g. boot sectors) in your computer should not be excluded from virus checks. You can specify here whether these should be checked on system start-up or whenever a media change occurs (new CD-ROM etc). Generally you should have at least one of these two functions activated.
- Check for diallers / spyware / adware / riskware: You can also check your system for dialers and other malicious programs with this software. These are e.g. programs that establish expensive, unwanted Internet connections, in which the potential for financial damage is no less significant than that of a 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.
- Only check new or modified files: If you activate this function, files that have not been changed for a long time and that were previously flagged as harmless are skipped. This provides a performance improvement in everyday work – without compromising security.
