There is one error happening in one of my local machines (3 machines), which remains unsolved for me.
Microsoft Windows XP SP3, all latest updates and the error happens on attempts to do something with
On any attempt to access them and
Invalid memory access error is triggered (code 998). Also, if you rename any existant file into a
.ver file, it becomes inaccessible.
Now, I could simply restore the working state of my machine (I've got backups), but this error seems interesting to me and I really want to solve it.
P.S There are people with the same error in the internet, but looks like it still remains unsolved.
Another P.S My first thoughts were about some sophisticated rootkit, which for some reasons was injecting it's code into the file reading calls, but my rootkit checks were unsuccessful.
