| Why is my system performance decreasing during computer scan? |
avast! 5.0 comes with a number of pre-defined scans installed by default (‘Quick scan‘, ‘Full System Scan‘, ‘Removable Media Scan‘, ‘Select folder to scan‘) and also you can create your own custom defined scans. All these scans can be performed simultaneously. But, if you execute too many pre-defined and/or custom defined scans at the same time, depending on your computer configuration you can observe some system performance degradation.
| What is Silent/Gaming Mode? |
At various times while your computer is running, messages may be displayed on your screen e.g. when the virus definitions have been updated, when an incoming email is being scanned etc. This can result in full-screen applications (e.g. games) being interrupted as Windows switches from full-screen mode to normal mode when the message appears. You can specify that messages will never be displayed, or will not be displayed if a full-screen application is running.
| What is the avast! Process Virtualization (avast! Sandbox)? |
This is a completely new feature in avast! Pro Antivirus 5.0 and avast! Internet Security 5.0 which allows you to browse the web or run another application in a completely safe environment. This is especially useful when visiting high-risk web sites, whether accidentally or deliberately, as the browser will be completely contained within the avast! Sandbox, preventing any damage to your computer.
The avast! Sandbox can also be used to run any other applications which you think may be suspect – you can run the program inside the avast! Sandbox to determine whether or not it is safe while remaining completely protected against any malicious actions that it may try to carry out.
To run an application or to browse the web using the avast! Sandbox, just browse the files on your computer to find the required application e.g. Internet Explorer. The browser or other application will then open in a special window with a red border, indicating that it is being run inside the avast! Sandbox.
Also you can further define applications that should always be run in virtualized mode, and trusted applications that should never be virtualized.
| What is the avast! Antispam? |
avast! Internet Security 5.0 includes a fully integrated avast! Antispam module to detect unwanted email.
Spam delivered to your mailbox can result in your mailbox quickly becoming full, as a result which, legitimate emails may not be received. It can also unnecessarily increase the load on the email server, internet connection, local networks etc.
The avast! Antispam module analyses all incoming email based on various criteria to determine whether it is legitimate. This analysis is based partly on a ‘Blacklist‘ containing the addresses of senders from whom emails should always be marked as spam, and a ‘Whitelist‘ which contains the addresses of known and trusted senders. These lists can be found in the antispam settings. For emails from senders that are not on either list, a content analysis is also carried out based on the specified scan sensitivity to identify email that should be treated as spam.
In the avast! Antispam settings you can also specify how spam emails should be marked. This can then be used to create a new rule in your email client, for example to automatically move the marked emails to another folder. The avast! Antispam module is effective for messages delivered to email accounts installed on your computer such as Microsoft Outlook, Outlook Express etc. but not for web based email accounts such as Yahoo, Gmail etc. which usually have their own antispam options.
| How avast! 5.0 secure web based email services such as Yahoo, Gmail, etc.? |
Web based email services such as Yahoo, Gmail etc. usually have their own security options, because e-mails are received and stored on the remote mail server and users access their email accounts remotely via web browser. In other words, the web based email services acts like any other website, and if you try to save, download or run some suspicious data from the web based email account, avast! 5.0 is able to protect your computer.
If you haven’t any information about security solution used by appropriate web based e-mail service provider, you can alternatively control your web based email account via browser launched within the avast! Sandbox to be completely secured.
| Why a lot of “clean” messages are being sent to my spam folder? |
This situation may be resolved by reducing the heuristic sensitivity. In the avast! Antispam settings is possible to set the scan sensitivity as ‘Low‘, ‘Medium‘ or ‘High‘. avast! will perform a heuristic analysis of all incoming mail to identify potential spam – the heuristic analysis comprises a large number of tests based on typical spam content or behavior and the sensitivity level will determine how many tests would have to be failed for a message to be considered spam. The higher the sensitivity, the higher the “pass mark”, therefore the higher the number of emails that will fail the heuristic test and will be treated as spam.
| Is avast! 5.0 able to protect me against phishing? |
Yes, combination of avast! Antispam and integrated URL blocking feature in avast! Internet Security 5.0 provides sufficient anti-phishing protection.
| What is the avast! Firewall? |
avast! Internet Security 5.0 includes a fully integrated avast! Firewall which can be controlled directly from the avast! Internet Security 5.0 user interface.
The avast! Firewall monitors all communication between your computer and the outside world and blocks unauthorized communication based on a number of ‘Allow‘ and ‘Deny‘ rules. In this way, the avast! Firewall can prevent sensitive data from leaving your computer and can also block attempted intrusions by external hackers.
| How can I can easily adjust the firewall settings to limit external connections into the maximum level of security? |
You should select an option ‘Airport/High Risk Zone‘ which is suitable when using your computer to connect to a public network and where you want to ensure the maximum level of security. This is the most secure setting and if selected, no incoming communication will be allowed, effectively making your computer completely invisible to others.
