Malware infection won't go!
Hello, I was informed that my laptop had a trojan. I was using AVG free version. I downloaded Malwarebytes which found some virals and dumped them. I ran the disk cleaner then reset the laptop. Ive been getting messages that malware blocked access to a potentially malicious website. I repeated the above process then downloaded and ran free Sophos, everything says my laptops clean. I also turn off all browsers in case it was a site I was on to no avail.
Please, can anybody help? (sadface!)
