First things first, run anti-virus software. I dont like recommending things too much, but I use AVG Free, which is a free anti-virus program that you can run on your computer that will constantly scan in the background for any bad stuff on your computer. You can find a link to that software
HERE .
Next thing is to install and run a firewall. There is lots of information going in and out of your computer all the time, and a firewall acts as a security guard at the gate, checking everything that your computer sends and receives to make sure it is authorized. I use Comodo, available
HERE .
Using these two pieces (which are completely free for non-commercial use) of software will go a long way in keeping your computer secure. The next step is safe computing practices, but this could arguably be the first step. You don't have to use this software specifically (which is why I don't like recommending stuff), but these are arguably the best free software available for this purpose.
Safe computing practices include the following:
- Only visit websites that you think are legitimate
- Dont open e-mails that you arent expecting, or look fishy. Trust your senses.
- Dont open attachment look funny for fishy. Again, trust your senses. If you werent expecting the attachment on an otherwise valid e-mail, it could be a virus.
- Log out of websites if you are on a public computer. It is good to make sure you are logged out by refreshing the homepage and make sure it doesnt say Hello (insert your username here), but rather prompts you to log in.
- Make sure secure sites are really secure. https or a little locked icon somewhere in your browser indicate a secure site.
- Keep up to date in your Windows and Internet Browser software. A lot of times they update to patch security holes, and these are good updates to have!
Those are the glaring things that Id recommend.
Now back to the OPs question, Im not exactly sure what you are talking about. I need more detailed information, and a screenshot (with sensitive info blacked out) would be helpful.
If anyone has any questions about internet security, or computer security in general, feel free to e-mail me and Ill respond as time allows.
