How to avoid installation of malware?
In order to prevent a computer from being infected with Trojans or other malicious programs, it is important to browse the Internet, download, install and update software with care. Do not open attachments or web links that are included in emails received from unknown or suspicious addresses, or/and these emails are irrelevant. It is important to keep installed software updated, however, it should be done using implemented, official tools that are provided by official software developers only. Additionally, all software should be downloaded using official websites and direct download links. It is not recommended to use various third party downloaders (or installers), Peer-to-Peer networks, unofficial/questionable pages and other similar sources. Same applies to various software 'cracking' tools, these tools should not be trusted. Their usage is a cyber crime and programs of this type often download and install viruses instead but do not activate software as expected. Moreover, have a reputable anti-virus or anti-spyware software installed and keep it enabled at all times. Tools of this type usually detect and remove various infections before they can do any damage. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.
