Is their any free and small sized antivirus program i can use?

THAT DOES NOT TAKE UP ALL YOUR MEMORY SPACE AND THAT DOES NOT SLOW DOWN YOUR PC. IVE USED AVAST, AVG, NORTON, MCAFEE, THEIR ALL SLOWS DOWN YOUR PC.

AVG does not slow down your pc totaly like norton. it is just its start up and scheduling options. i use AVG i'm 128RAm only and i disables all its unneccesary start-ups. (knowing the fact that i can run it manually) and still it saves me from threats.

forget avg 80% detection ...thats not good ...the newbies are all in love with it ...avast is pretty good ...im using avira here is a link for free download ...is really good on system ...and 96% detection rate is not bad at all ...

Try the free virus scanners at http://blog.360.yahoo.com/blog-sAFtLsc8e... and see which one will help you .
Then no, none that I know of. I would recommend Nod32, but it's not free. It has a minimal memory footprint though. Also, using all caps is obnoxious.
AVAST! is free, on acess protection dosnt slow ur PC down at all but has stopeed me gettin viruses so many times--great u should try it
Avira AntiVir PE Classic for sure! It is one of the lightest AV's available - currently using less than 10MB memory on my PC, yet it has one of the best detection rates and heuristics of all the AV products.

AVG
avast and avg slows down your pc?

i dont think so, ive try avast and avg (both, the free version of course), they are ok for me.

but for the best free antivirus, try Avira Antivir PE Classic.

hate to burst your buble folks but norton 2008 is very light on resources and remains the best protection software. now go get a job so you can buy it. after all thats why u dont like norton right? because you cant afford it.\

EDIT: hi peace and 75% of the detections are false positives. grow up.
