Malicious programs, otherwise called viruses, are a serious threat to any computer. And it's not only a noticeable deterioration in the performance of the machine. Viruses can damage the vital registry files responsible for the operation of the entire system. After such an intervention, the computer will cease to function normally, and in particularly serious cases of system infection, it will not be able to load it correctly.
Another problem concerns the Internet and individual sites to which some malware block access. This is one of many reasons why Contact, Classmates, or another popular resource does not load . What to do if one morning you decide to visit your page, and in return you see only an error message or an endless download in the browser?

Also do not forget about antiviruses. If one does not help, you can always install another and scan the computer again. The main thing is not to panic. It is possible that while you were looking for why "Contact" is not loading, the site simply carried out technical work.
