The site being slow is probably the server side of where this site's Server is located. I have hosted my own website and AcId owns his own. AcId's site has always been slow. I don't know if this site has a limit on megs or anything. Some sites do that for the bandwidth they have to conserve for others.
Malwarebytes is a good program to be free. I would suggest Norton Internet Security, i have had Norton Internet Security for 5 years now. I have been virus free for 5 years. I have one maleware that never leaves. But, it is because of internet explorer. It will always be there. Free is decent, but paying makes all the difference.
Viruses and Malware mostly come from porn. I am just saying... lol But, Malware and spyware will always be there. Internet Explorer is considered Spyware. It is the crappiest and slowest web browser you can use. If you are using it. Switch to Firefox, Google Chrome or any other browser related to these two. You will surf/browse the internet 2x faster no matter the performance of your PC. In order to really help you, Omni. I would have to know what sites you go to. You can admit porn. I have looked it up to and use to all the time. But, you just have to tell me. What type of OS are you using?
