The reason for the error is most often the following:
- possible attempt to open broken video files and images;
- The likelihood that codecs are obsolete or damaged;
- The likelihood of a dangerous virus.
The Windows system program, encountering various errors of syntactic nature, can loop code action and use a large number of resources to solve it. As a result, com surrogate loads the system.
Under the com surrogate process, a virus can also be disguised. With this option, you can observe the following patterns:
- In the presence of a virus, the operation of a laptop or personal computer can be significantly slowed down, and sometimes Windows may even hang;
- You quite often observe that software products for working with the Internet or browsers hang;
