Nikita,
Glad that all turned out ok....for now. Keep an eye on your computer for any suspicious changes.
As for Logging programs.....simple. They are small programs embedded in your system to record keystrokes...ALL OF THEM. So these programs record website urls, passwords, credit card numbers, email, personal information.....
eveything you type in to the keyboard. Some "keyloggers" ,as the are called, can email a report to an outside computer for which the email address was entered when the program was installed. (SC Keylogger is such a program which you can download from CNET)
You can easily research such programs by doing a web search for "keyloggers" or "computer logging programs". The 'hows" and "whys" of their inner working are too confusing for me to explain.
Just be aware that they exist.
You may want to try this ANTI-keylogger evaluation program .

I have not tried it myself, since I would know if I am monitoring myslef....
Their useful purpose is to monitor children's activity, or other users activity on the same computer to prevent abuse or unauthorized usage.
This board is a wonderful place to learn about Avast and anti-virus software. The users and the Alwil team are great.
If I can be of further assistance, post on the board, or use the IM feature.
