It is generally believed that no one antivirus or spyware protection program can catch everything. Having said that, running two antivirus programs in real-time protection is a no-no. Antivirus programs do not play well together, can cause conflicts, and possibly may miss infections altogether. Therefore, a better set-up is to have one antivirus and a couple of real-time protection programs such as Windows Defender. I would run on-demand scanners such as Adaware and SpyBot weekly**.1) Scanning
Ad-Aware doesn't have a real-time protection. So, how often should I scan for malware?
Is TeaTime (or something like that) form Spybot a real-time protection? if not, the same question as for Ad-aware goes here.
** The frequency really depends on how often your computer is connected to the internet.
While this will not do any harm, if you have everything set correctly and the programs are updating themselves daily (or whenever you start your computer), there shouldn't be any need. If you want to run full scan from time to time then weekly** is OK.Other programs that have real-time protection, should I run them from time-to-time for a full scan? If yes, how often?

We tend to recommend free programs that will offer good protection. Sitehound is an excellent program but you need to purchase it to receive the full benefits. Another very good program is WinPatrol but, again, you need to purchase it to get the full benefits.2) Firetrust - Sitehound
ChrisRLG mentioned on the link you gave me that it's a must as an anti-malware program. You haven't mentioned it, so should I skip Sitehound?
Windows: Should be on automatic updates.3) Update
How often should I manually update certain programs that don't have the auto-update otion?
Antivirus: Daily - it should update itself when you first switch the computer on.
Other real-time protection programs: Daily - they probably update themselves before running.
Other protection programs e.g. Adaware: Weekly - check for updates before running.
OK, I'll try to explain...4) Host file
I need help here, because I understood nothing. What should I download on the linked page you gave me?
When you type a web address in your browser to go to a web site, the words you use have to be converted into numbers, an IP address, that the internet will understand. For example, the internet recognises the bbc web site as 212.58.240.32 (type this number directly into your browser's address bar and see what happens).
To do this conversion of words to numbers, your browser will look at the Hosts file first then your ISP's DNS servers.
Generally, your Hosts file is empty so your browser will then look to your ISP for the conversion.
So, two things:
- Malware can add entries to your Hosts file to stop your browser reaching certain web sites, usually security sites, or can re-direct your browser to another (false) site. To stop this, you need to protect the Hosts file with a program such as Hostsman (free) or WinPatrol.
- By purposely adding certain entries to the Hosts file, you can stop your browser going to dodgy sites or downloading adverts. The Hosts file available on the MVPS web site has many such entries and can be downloaded to your computer. Read "What it does" on the web site.
AVG-AS is not an antivirus program in the same sense as NOD32 so it's OK to keep both. The AVG-AS Guard, the real-time protection element, will stop working after thirty days unless you purchase the program. After the thirty days, you must update and run the program manually.Updated question:
What should I do now with AVG anti-spyware? Since I already have a NOD32 antivirus?
Hope the above helps.
