Zywall Block Outgoing Ports
According to your needs, you can configure Windows Firewall settings (block or open port in Windows 10/8/7l) and restore defaults if you are unsatisfied with the default Windows Firewall settings. However, for this, you need to get to the advanced settings of the firewall. This is simple, simply open up the control panel and in its search box type – Firewall. Then open Firewall and click on its ‘Advanced Settings’ link.
I don't block any outgoing traffic, though there is a content filter (blocking naughty stuff and P2P traffic), IPS, and gateway AV. However, I suppose it's a good idea to block outgoing port 25 as a precautionary measure against infections that send out spam since everything else uses alternate/secured ports anyway. BitTorrent can run on any port, and can be wrapped inside SSL, so blocking by ports or traffic data isn't going to get you anywhere. My suggestion would be to block HTTP traffic on any port which matches the tracker announce protocol, as per the specification. This won't work if the tracker is running on HTTPS, but most don't.

Running Smart Scan in Avast Antivirus. Performance issues: items such as junk files and unnecessary apps, or settings issues that may interfere with the operation of your PC. Tick the box next to an unsecured threat, then click Resolve. Alternatively, click Skip for now to resolve the vulnerability later. Avast stuck on performance issues. May 11, 2019 I can close the program, and even put the computer to sleep, and retry Smart Scan but it tells me it’s 'still running' and it’s still stuck on Performance Issues; closing does not restart/reset Smart Scan. Only a full reboot will reset Smart Scan, but the results are the same as it still gets stuck on Performance Issues.
Click Next to continue.
Next, select ‘Block the connection’ as the Action and click Next.
Later, select all the profiles available for different type of connections (Domain, Private and Public) and Click Next to continue.
Give a name of your choice to the new rule. I used ‘block suspicious ports’. If you want, you can add the description to the new rule. This step is however optional.
