No problem with questions, that is what I am here for. :wink:

2-way protection for a FW means that the FW is protecting you from things coming into your machine as well as going out. The XP FW only offers 1-way protection, so it is almost worthless. You need 2-way protection. Some 2-way FW’s that are compatible with Avast are Online Armour (free or paid), Outpost (free or paid), Comodo (without antivirus). As with any security program, you will need to add both the FW and Avast to each other’s exclusions to avoid a potential conflict.

When you get a notification of a virus, do not shut the machine down. Some malware actually will prevent you from booting up. So instead follow the prompts from Avast and put the virus in the Virus Chest, where it is safe…it is an isolated area where the rest of your machine cannot gain access to it. We recommend you leave things there for at least 3 weeks. During that time after getting virus definition updates, you can right click the items in the Chest and rescan it. If it comes out clean, you can restore the clean items from the Chest back to your machine. This might be important if it is an important file. Of course running a scan is always a good thing to do as well; make sure you have the updated virus definitions before you run a scan. If highly suspicious of something, run a scan, but also run a boot-time scan as well. One thing you do not want to do is to “delete” something. When in doubt about something, come to the forum and ask questions. We are here 24/7 even for malware removal.
