updated configuration in first page, actually changed configuration more than a year and half ago, but forget to update here.
Changed Windows XP installation security with CIS .
Windows 7 security is now depends on Avira Free.
Removed Winamp, and made my default audio player AIMP.
PotPlayer is doing good for me.
Forgot to mention here about WordWeb previously, now added.
Can't remove IDM
still no free option available
, but also added XDM, not a full-featured substitute but doing OK.
Another thing, i like to mention here, i stopped experimenting with different security softwares by installing and uninstalling again and again, This configuration is working quite Ok for me, no infection yet. Actually, i can't remember when my PC infected last time, may be 3/4 years ago. I take very care when i have to insert Pen Drive/USB Drive into my PC.
Hope for Best.
