My computer is invented with Mysites123, that can not be detected by Avast. Could Avast team help me, because every time my computer slows down I am sure it is because of "hxtp://www.mysites123.com/?type=hp&ts=1456455538&z=8908f3d6b047df55af83a6ag1z3wcq8zbwew6w0c3b&from=amt&uid=wdcxwd3200aakx-001ca0_wd-wcayuh3284" and "yoursites123" I have used another program to detect, delete and fixe them but these always infect my computer again.
Would you please Avast team help me. Thank you
