How to use AVG Antivirus
Change the schedule of the system scan
In the standard settings AVG Antivirus will make every day a full system scan, but like I said is this not really necessary. So the first thing we have to do is changing the scan schedule. If you prefer to keep the daily system scan than skip this part. First open AVG Antivirus user interface (AVG is already running), double-click on the AVG icon in the system tray. In the AVG interface click on Tools –>Advanced settings from the drop-down menu. On the left side select Schedules and Scheduled scan. On the right side you can set the scan schedule, there are choices like once a week. If you want it once a week, select the day and time you want to scan. Another option is to scan every time you start your computer.
Update AVG manually
To make a manual update of your database, go to the user interface and on the left side click on the Update button. AVG will check if there are updates available and if yes, it will start to download and install. Once it is finished you see a message that the update has been completed.
Scan certain folders or files with AVG
If you want to scan only one or more folders or files, go to Windows Explorer and search for the folder you want to scan. Once you found the folder or file right-mouse click on it and select Scan with AVG. Avg will scan now the file or folder for viruses and spyware.
AVG Antivirus will protect you against Viruses and Spyware, it has an Email Scanner, Link Scanner and Resident Shield. The Email scanner scans all incoming and outgoing emails for viruses, once it found an infection it will bring it in quarantine. The Link scanner has a surf and search shield which protects you against harmful web and search content. The Resident Shield scans files if they are copied, opened and saved and prevents activation if the threat will be found. It also provides essential protection of the system areas of the computer.
