Frustrated and Worried

I am so frustrated and worry during the since last week.I' worrt of my laptop been infected by virus.The antivirus I'm using now is AVG 8.0 bt most of my UNImate said Avg is the most lousiest antivirus if compare with KASPERSKY AND AVIRA.I wanted to change the my antivirus to KASPERSKY last sem but my uncle said AVG 8.0 is good also.I have no choice but listen to him because I dont know anything about software.In conclusion , I'm a COMPUTER IDIOT!!(can you understand)!!

I'm so worry my laptop will shut down suddenly then I think there will the end of my day already.In fact, I cant live without my laptop.
I need it to do my assignment.
I need it for my research
The most IMPORTANT task is,
IT's my entertainment tool besides my MP3 and mobile phone.
I cant live without a laptop in one day.

I have thought of reformat my laptop but I cant because I dont have the software disc with me.
So, I cant reformat.
I have thought of purchase Original KASPESKY but is kindna expensive.
I cant reformat so the only thing I can do is install new antivirus.
I hates the library wireless.It's the main reason why I got virus.

Why there is viruses in the world.
'They' should be killed.
'They should be destroyed.
Perhaps 'they' shouldnt exist in the world.
'They' are not belong to the IT world.

I really need suggestion right now.I dont want my laptop to condamm when its at the climax period in my 2nd sem.
Gosh!!
HELP me!!
Please.
Thanks.
Hope I can settle it soon.
