>>>I will finish this Windows Essential AV full scan. Then I will make another backup (I don't want to do it during the scan). Then, I don't know yet. Btw, I killed all the PUAWZEE.EXE programs (they all have description aaF0roP7Mk) and they (so far) didn't restart. All SVCHOST.EXE are also gone. You are right, however, the system is not stable. But to reformat, restore, and reinstall all application will take at least 3-4 days. What a PITA. Thank you for your help.
