At last my windows working!!!!

After years of frustrations and holding my head with windows xp, I am now experiencing rare happiness and relief as there is no more crashing, restarting.. and who could forget those bad and teasing computer viruses ( sometimes i felt that these virus are worse then even dengue virus!!!!).... well i think virus was biggest culprit in my system crashes.. thats why lots of people migrate to macs as macs dont have viruses.. i tried lots of antivirus.. from norton to mcafee and from avg to panda... but all in vain...also dont forget there thrust for huge system memory n resources.. well then i tried avira antivir personal antivirus edition.. and then all is sweeter..its light, fast and detection rate is superb.. also after that no virus has able to infect my pc.. but also i learned that antispyware is also essential....as earlier i did not bothered to use one... now i use spybot s & d....its decent... being freeware...its immunization work wonders.....now after antispyware i also installed comodo firewall 3...... its gr8 ...... its blocks all intrusion attempts...
