Let me write a random sequence for example:
TEST1_TEST2_TEST3_TEST4_TEST5_TEST6_TEST7
Now If I try to copy it and paste back this results in:
TESdAmVfGT1K8MnsmuYQby2wJibmeiHnQwVHTMy37cr8fluRvLc5ket1J2WMuE8JJeN5WsA1v8DxhXBezXy1STMy3XuRvLxEXuRvLxE
and if i paste again:
TESdAmVfGT1K8MnsmuYQby2wJibmeiHnQwVHTMy37cr8fluRvLc5ket1J2WMuE8JJeN5WsA1v8DxhXBezXy1SdAmVfGT1K8MnsmuYQby2wJibmeiHnQwVHDxhXBezXy1SdAmVfGT1K8MnsmuYQby2wJibmeiHnQwVHLsoDBC2dQBZXCXd6nk1g1MRU4nUMXAHNFBEJhkTZV9HdaL4gfuNBxLPc3BeMkLGaPbF5vWtANQuhojvBrujRSdAmVfGT1K8MnsmuYQby2wJibmeiHnQwVHlVl
If I do it with the smaller sequence it works fine. I.e I can copy TEST1_TEST2_TEST3_TEST4_TEST5_TEST6 (first letters of the sequence above), but if I add 1 more letter I can't.
I can't find a person who could reproduce the problem yet. I have Windows 10 Pro, though my friend with the same Windows can't reproduce the problem.
How could this happen? How to fix this?
I think it's a malware... just try with Malwarebytes...
