I downloaded "SpyDetectFree(64bit)" on a flash drive and then plugged it into my HP Desktop Tower. It said I was probably being spied on and the culprit was atcuf64.dll. It said that this program, which it confirms is a part of my BitDefender Security Program on my home computer systems, might be recording my keystrokes! I called BitDefender, they were not sure about that, but said they would check and call me back, they never called me back, and they sent me a message that they thought the freeware I used to scan my system might be malware itself and the issue, not them!
The freeware was from the website FreeWare and it's checked before it's made available for customers to download and use, so, I do not know what to think about this!
For the record, I definetly am having issues with my home electronic system after it was hacked about 6-7 months ago....super slow, etc...
