Woohooo!!! My problem was solved!
To fix it was too simple but I never would believe that all these bugs caused by additional virus patches stored at default folder!
I removed them to another location and my virus is working without any problem!
I was not not told that additional patches stored in its default folder may cause problems like that, and I wasn't received this information from access support.
Hm. Maybe I wasn't got this info from e-mail received from support because my english isn't perfect...
