The virus is slightly polymorphic and uses several layers of self-encrypton. Infected EXE files are converted to COM type.
The virus either inserts its body into the victim file or appends it to the end of the file. When resident, the virus occupies 8 Kb of memory in highest addresses below 640K boundary. After certain number of reboots of an infected system the virus trashes data on the first cylinder of a hard disk (Boot sector and FAT) and displays the following message:
Hello!!! My name is Andryushka I come from Perm,USSR
Then it hangs the computer.
