Thank you every one for help.
So far I did:
1. Enabled DEP for all programms
2. UAC is on default level
3. Installed GeSWall. It seems to that it functions the same way as Defencewall HIPS, but has free version.
What do you think about it's free version is it any good? It wasn't preconfigured so I had to put my browser, p2p, msngr and players isolate when start or isolate when tried access. So is it's free version worth having?
4. Installed Shadow Defender. As I understand it has function to put PC into virtual machine and rollback when restarted. So in theory any change I will or any virus I get do in Shadow mode should not affect after restart, is it right? I found it useful program to test other programs in shadow mode (problem only with programs which require restart) and do online scans as there is a risk that I can face some rogue AV. I have scanned my PC with
Hitman Pro 3 - SurfRight and Prevx in shadow mode, not to run risk.
So am I using this program right way, and is it really safe? Or should I get normal Virtual Machines like Vmware or VirtualBox?
5. I am thinking about WinPatrol. Is it's free version good enough?
6. And only serious problem is backup. As I dont have external hard drive.
Maybe I will backup Laptop A --> Laptop B and Laptop B --> Laptop A
or is it not good idea?
Thank you everybody again!
