Hi NGN,
I am not sure what is kind of virus/malware that infected your system, but for sure that is one of malware family.
What did i mean is after your installed with MalwareBytes or Super Antispyware, please do database update first.
And then you could do scan with your system.
If still face a problem, please :
1. Download
Combofix 2. Download it and save with rename the file, like example : 123.exe
3. Please stop all of windows activity included avast antivirus protection
4. Please click your download fil and start the scan
Once the scanning process has started please DO NOT click on the Combofix window or attempt to use your computer as this can cause the scanning process to stall.
It may take a while to complete scanning and this is normal.
After the scan has did, please submit your combofix.txt in to this forum.
