Hey you all. Adw found this registry entry:
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.com/search?q=hp%20assistat&form=WNSGPH&qs=SW&cvid=abee8ac32569465895bba270caef994f&pq=hp%20assistat&nclid=0ED39ADB9642D6A945440994DFD21348&ts=1462992234518&nclidts=1462992234&tsms=518
Is it a virus/malware/spyware?
Thanks everybody.
