Manual virus check - Advanced
You can create additional virus scan settings by clicking the ADVANCED button.
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. Selecting the option "Program files and documents only" entails certain speed benefits.
Heuristics: In the heuristic analysis, viruses are not only detected by the virus database, which you receive with every update of the antivirus 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. 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: 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 check your system for dialers and other malicious programs with this function. 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.
Check for rootkits: Rootkits attempt to evade conventional virus detection methods. Additional monitoring for this malware is always advisable.
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.
Generate log: You can use this checkbox to require the software to set up a log for the virus check process. This log can be viewed in the Logs area.
Offer virus checking for removable data media: If you check this box, whenever a removable data medium (USB stick, external hard drive etc) is connected to your computer, you will be asked whether the device should be checked for viruses.
