avast DO NOT detects this virus

i’ve found it here

hxxp://193.104.153.43/freeporn/?uid=18

there u’ll be suggested to install flash player
after reboot - u’ll find a new window on your desctop
which is impossible to remove

avast v. 4.8 home ed. doesn’t help

Malwarebytes’ Anti-Malware (MBAM) blocked it:
IP-BLOCK 85.12.24.85

Looking for pr0n will get your system infected.

Not only visiting sites which are at higher risk, you then accept an offer to install a flash player ???

Common sense plays a huge and largely unreported part in your system security, your AV, Firewall and any other software are supporting acts.
