My Computer is running very slow someone help?

Question

I have AVG antivirus , Spybot S+D , Ad-Aware and AOL spyware protection. I have scanned and when i first did i had something like 27,000 files infected with a Trojan Generic virus. Now it says i have deleted them all but i still have many problems for example:
-My pc is running extremley slow.
-My disc drive does not recognise any CD's.
-My programs freeze , and turn to 'not responding'.

I have already tried to defrag my drive , i have scanned the life out of it and supposedly deleted everything. But still detected by my AOL is something called Abetear A adware and i wonder if this is slowing my PC greatly. I would be greatly apreciative if you could help , Thankyou.

Since you have tried many methods, the only option left is to format the system once and reinstall all the softwares.

Also no need to multiple programmes for antivirus or spyware. Just keep a programme for antiviurs and one programme for antispyware

before that if possible try applying norton system works.

I think first of all you should stick to one good antivirus and spyware program, also go into your internet options and delete your browsing history and everything else like temp internet files... It sound like many of your files got corrupted and you might just have to reinstall your windows software....
