How did I get infected with?

The PROXYCHECK.EXE adware did not appear by magic. This parasite is not an ingenious virus either. No! It is a simple PC program. As any other program, it needs your approval to be installed.

If you are offered an Advanced/Custom installation option, by all means, select it. Under it, you will be presented with a list of the “bonus” software that is about to be installed. You can deselect the extras and still install the program you originally planned to set up. If you use the Standard/Fast installation, however, all extras will be installed without your explicit approval. Do not allow this. This is your computer, after all. You decide what to be installed on it. Don’t let others decide for you. Moreover, such third-party software, more often than not, is malicious.
