June 29, , For those with high bandwidth connections, in excess of Mbits. Some considerable time ago when very fast broadband started to take off excuse pun some noticed a slowdown in their downloads as the bottle neck between streamed intelligent scanning where the system was playing catchup. It was suggested that those with very high bandwidth should consider switching off the ‘Use intelligent stream scanning’ option in the web shield.
Web Shield – Settings
Web Shield – Settings Manage these settings from: It scans data that is transferred when you browse the internet in real-time to prevent malware, such as malicious scripts, from being downloaded and run on your PC. By default, Web Shield is configured to provide optimal protection when switched on. We therefore strongly recommend you keep this Shield turned on at all times and only make configuration changes if you have an advanced understanding of malware protection principles.
Use the tabs on the left-side of the window to manage different aspects of Web Shield behavior. After making any changes, click OK to save Web Shield settings. Main settings This screen allows you to set the main parameters for Web Shield. Web scanning: Warn when downloading files with poor reputation: We recommend that only novice users tick this option.
Scan traffic from well-known browser processes only: By ticking this option, data traffic from these less known web applications is authorized and is not scanned for malware by the Shield. Additional options can be configured in the Web scanning section. HTTPS scanning: If disabled, only websites with unsecured connections are scanned.
Use intelligent stream scanning: If you untick this box, the whole file is downloaded to a temporary folder, then scanned. Do not scan trusted sites: Block malware URLs: Script scanning: Additional options can be configured in the Script scanning section. All settings are enabled by default, except the subsettings for Web Scanning. Web scanning The Web scanning screen allows you to specify which type of content Web Shield scans. The following options apply if Web scanning is enabled in Main settings.
Scan all files: This option is selected by default. Scan selected file types only: If selected, tick the relevant option, then type the file extension into the text box. To add another extension to the list, click Add. To remove an extension, click the relevant row, then click Delete. Do not unpack archives with valid digital signatures: The asterisk replaces zero or more characters, whereas the question mark replaces a single character.
For example: To scan all file types with two characters in a file extension, type?? To add a new item, tick the relevant option, then type the URL, extension, or file location into the text box. To add a process, click Browse, select a file. To add another item to the list, click Add.
To remove an item, click the relevant row, then click Delete. URLs, extensions, and file locations can include wildcard characters? The asterisk replaces zero or more characters, and the question mark replaces a single character. Exclusions that you specify on this screen only apply to Web Shield and do not affect any other scans or Shields. Actions The Actions screen allows you to configure automatic responses to any online threats detected by Web Shield.
Abort connection default: Remaining connected may be risky. Tick Show a notification window when action is taken to be notified of all actions ticked by default. Packers The Packers screen allows you to indicate the compressed file types that you want Web Shield to unpack when checking for malware.
For example,. The Shield is better able to analyze files for malware when files are unpacked. To unpack a file is the same as to extract a file from an archive. Original archives, including the files contained within, remain intact when being processed by the Shield. By default, All packers are ticked. For more information about a specific file type, tick the file type and refer to the information under Packer description at the bottom of the screen. Sensitivity The Sensitivity screen allows you to define the following settings for Web Shield: Specify your preferences for the following options: Use the orange bars to indicate your preferred level of heuristic sensitivity.
The default setting is Normal three bars. With higher sensitivity, Avast is more likely to detect malware, but also more likely to make false-positive detections incorrectly identify files as malware. Tick Use Code Emulation to unpack and test any suspected malware in an emulated environment where the file cannot cause damage to your PC. This option is ticked by default. When this option is ticked, the scan is slower but more thorough.
PUP and suspicious files: The more options you tick and the higher the sensitivity you set, the more thoroughly the Shield scans your PC. With higher sensitivity, false-positive detections are more likely and more resources are consumed on your PC. Site blocking The Site blocking screen allows you to block access to specific websites. This can be useful if you want to prevent children or other users from accessing certain content on the web.
To block a website: Tick the box next to Enable site blocking. Type the URL address of the website you want to block into the text box. Click OK. To add another URL to the list, click Add. To remove a URL, click the relevant row, then click Delete. To block all html pages with the filename containing a single character in domain of a particular website, type example.
Script scanning Script scanning prevents browsers and other applications from running potentially malicious scripts. This includes remote threats from the web and outside sources, local threats downloaded to your hard drive or in the browser cache, and scripts that come from encrypted connections.
This screen allows you to select which browsers are scanned, including other applications which use Windows Script Host WSH to run their own scripts. All options are ticked by default to ensure your full security. These options apply if Script scanning is enabled in Main settings. Script exclusions The Script exclusions screen allows you to exclude specific web addresses from script scanning, so you can access all content on those websites. To exclude a website from script scanning, follow these steps: Tick the box next to URLs to exclude.
Type the URL address of the website you want to exclude into the text box. Use exclusions only if you are sure the website you want to exclude from scanning is safe. Report file The Report file screen allows you to specify whether you want Web Shield to produce reports of scan results. When troubleshooting issues with Avast Support representatives, you may be requested to provide a report file.
To generate automatic scan reports, follow these steps: Tick Generate report file. Manage the following settings: File name: File type: If file exists: Define the contents of the report: Infected items: Hard errors: Soft errors: OK items: Ticking this option results in very long reports. Skipped items: Report files are saved in one of the following locations: Windows 10, Windows 8.
Adding Websites to the Exclusions List
June 07, , The slowdown started the moment I got rid of ‘browsercleanup’!!!!! BTW, on prowling around I found that browsercleanup has a bad reputation so I’m glad it’s gone. It was deleting things I wanted to keep, deleting without my knowledge or consent. So I had to keep reinstalling things, over and over, with no slowdown.
