explorer.exe Malware?

Viruses and worms
1

My Windows XP computer has come to a halt recently with all sorts of processes running simultaneously and slowing it to crawl. I have run Malwarebytes, S&D, Hitman Pro etc but Avast keeps detecting the following non-stop:

Object - http://reannewscomm.com/ads.php?sid=1803
Infection - URL:Mal
Process - C:\WINDOWS\explorer.exe

The other processes include dllhost.exe, ctfmon.exe, msiexec.exe. These also appear on closable windows when I try to shut the computer down and have to be repeatedly shut down before a very suspicious full screen fake news style advert appears and the computer finally shuts down. Clearly something very shifty going on. If anyone has any advice or if I can provide any further information please respond!

Basically nothing has changed, still horrendously slow to do anything and avast keeps popping up the same alert every few seconds.
