If you suspect that your computer is infected (it behaves abnormally), run an on-demand computer scan to examine your computer for infiltrations. From a security point of view, it is essential that computer scans are not just run when an infection is suspected, but regularly as part of routine security measures. Regular scanning provides detection of infiltrations which were not detected by the real-time scanner at the time they were saved to the disk. This can happen if the real-time scanner was disabled at the time of infection, or the virus signature database was obsolete.
We recommend that you run an on-demand scan at least once or twice a month. Scanning can be configured as a scheduled task in Tools > Scheduler.
