Things to be kept in mind while using the Internet


There is always the temptation to try new things and do all sorts of things while on the net. While this can be an adventurous trail it is also one of the security risks. While on the net one should avoid the temptation to open each and every pop-up message that appears on the screen. These could be adware providing better performance for your PC, but they could also contain spyware that are not detectable by your antivirus. In addition to this, the user should try and avoid as much as possible to leave his or her email addresses on sites visited. This can be a cause of that nuisance spam e-mails that you keep receiving.

Try and avoid opening e-mail and promotional attachments that are sent to the inbox. These attachments in some cases contain spyware and malware that may be detrimental to your data security. For those entertainments gurus, file sharing applications i.e. Kazaa have been known to have spyware, try to minimize the use of file sharing software and try to use the legal way of acquiring MP3s.

How to keep your PC safe?

The automatic updates need to constantly on in order to search and download the latest virus update files for the database. In addition to this the automatic scan schedule should be turned on in order to scan the system at all times at a specific time of the day. Installation of additional tools like Trojan blockers and antispyware can help in detecting and removing those malwares that slip past the antivirus program.
