I am currently using Fsecure antivirus program could some one tell me whether
this is sufficient enough to protect my PC from unwanted guests or do I need
more programs to secure.
"If you think all one has to do is installing a software suite to protect
your computer then you're dead wrong.
If you think with a security suite in place everything is done which one
can possibly do to have security then you're even wronger.
If you're really concerned about the security of your computer and data
then you just will have to learn the rules how to keep secure."
One-click applications are not the answer to your situation!
It's time you're educate yourself and initiate some kind of security
concept!
1. For day-to-day work/browsing operate as a 'normal' user i.e. utilize the
Limited User Account (LUA) and use the Administrator Account (AC) only
when absolutely necessary.
2. Secure, tighten up your Operating System (OS).
3. Keep your OS and all software on it updated/patched.
4. Reconsider usage of IE and OE.
5. Don't expose Services to public networks.
6. Use the in-build firewall and if applicable use a router.
7. Do not to use TCP/IP as transport protocol for NetBIOS, SMB and RPC and
leave TCP/UDP ports 135, 137-139 and 445 closed.
8. Routinely practice Safe-Hex.
9. Routinely backup your data; Develop a Back-Up Concept.
10.Familiarize yourself with 'flatten' and rebuild your OS.
11.Review your installed 3rd party software applications;
Remove clutter.
Detailed elaborations pertinent to the above mentioned points can be
provided.
I very frequently seen MVPs mentioning spybot and adaware and I haven't got
a clue what these programs are.
