No disrespect to Paul but I'd be EXTREMELY cautious with sites that only offer a 'download OUR software' fix.
In fact I'd say stay well clear of it.
More often than not these so-called 'Fix' downloads are no more than just a fake search for viruses in an attempt to get you to buy their software....which usually does no more, often less, than any FREE anti-virus readily available from reputable companies.
What OS and browser are you using?
What Anti-Virus do you use? (Get rid of it as it obviously doesn't work! LOL)
An 'industry standard' for malware, adware, viruses, trojans, worms, sniffers, loggers, backdoors, ransomware, BHO's etc etc is:
MALWAREBYTES
Read any 'virus' related article and more than likely this will be mentioned....and with good reason...it works.
If you are on a PC I can go into other things you can try, If you use a Mac then I'm afraid I'm pretty useless to you.
