Mcafee AV and Advanced System care by Iobit antimalware. It is someone who knows us, we think and has a personal problem with us. They have changed passwords, got into my husbands debit card, which the bank refunded, post as us on facebook and have sent me emails under a temporary email, showing me copies of private FB messages. We have contacted the police and FBI, but they pretty much have been no help.
Ditch the crap AV (yes, McAfee is bad). Get a free alternative such as Avast, Avira, or Bitdefender Free.
Drop the Advanced System Care as well and get Malwarebytes Antimalware (the free version is fine, no need to get the paid Pro version).
You'll want to do several things...
1) Download those programs, as well as HijackThis from sourceforge.
2) Go to
IP Chicken - Whats my IP address? ip address lookup and make note of what your IP is (don't post it here...just write it down or something for reference later)
2) Install / update them on all systems on your network
3) POWER DOWN (i.e. unplug from the AC outlet) both your modem and router (if they're 2 separate devices) to completely disconnect from the internet - these will need to remain unplugged for possibly up to 24 hours so that you can get a new external IP
4) Open MBAM and run a Full scan on your systems. Delete anything it finds. Save the log file.
5) Run a scan with whichever AV you chose from above; remove anything it finds
6) Go to a completely different network / computer (an internet cafe, a friend's or family's house, something) and change ALL of your passwords to your accounts (Facebook, email, bank accounts, online shopping sites, etc...pretty much everything you log into). The point here is changing all account passwords from a known clean (i.e. non-infected) computer system / network.
7) Repeat the scans from 4 / 5 until they come back with no results.
8) Once the scans are complete and don't find anything anymore, plug your modem back into power and let it boot up (may take a few minutes).
9) Go to
IP Chicken - Whats my IP address? ip address lookup again and check if your IP is different from step 2... if it is, great. If not, either unplug it again and wait, or contact your ISP about releasing a different IP as you believe you may be being targeted online by your IP address
10) Once you have a different public IP address, it may also be a good idea to change your router's SSID / wifi password. Make sure you're using WPA2 level of password encryption. Also, if your router has WPS enabled...DISABLE IT. You can do this from the router's web GUI.
