Currently I am using Bitdefender AntiVirus plus and every time I restart my computer, BitDefender notifies me that it has a blocked something. I look into further details and it specifies that PowerShell is trying to communicate with an external IP. It will keep popping up until I end both of PowerShell's processes with task manager. The IP has a format of xx.xx.xx.xx/assassin, which seems a little suspicious to me. I've run many virus scans with different programs and am still having the same problem.
The only documents I have opened are ones from school, although I guess that doesn't rule out the fact of a virus. I do have the same symptoms except for the ransomware part. I will runhitmanpro and see if that finds anything
