Yahoo Messenger Errors

I have or HAD yahoo Messenger 8.01 and all of a sudden when I try to use the IM it gives a script error as it is saying there is not enough memory ??   It worked fine for years and now all sorts of problems...  I have 4 GB of RAM  with an AMD X2 6400 cpu   BUT it was giving error before the CPU change.

I have uninstalled and reinstalled several times.. Only differential is that Kapersky AV  may be doing something as problems started around that time ?

1st  uninstall Yahoo
if you are using windows 2000/XP, download CCLEANER and run clean, and run registry fix (make a backup copy of your old registry if something go wrong you can restore, never happened to me though!).

make sure you uninstall Yahoo messenger before you do clean, restart and re-install.

I hope this will solve your problem
Good luck
Have you tried disabling Kaspersky or uninstalling it to rule it out as the caused?

no I thought about Kaspersky  but did nothing with it so far as it is my choice for AV.

I did however uninstall it and clean the registry but not with ccleaner   JV16 and RegFirstAid..

YM 8 causing some issues.
Can you try YM 7 version and see, if it works consistent?
Let us know how you do in progress with YM 7.
How ever I know your requirement on YM 8.
Btw, if you can confirm if you dont have above mentioned issue with YM 7 then we can continue from that point.
Reference Kaspersky >>           >as it is my choice for AV<
Yes, it is an excellent scanner but did you actually uninstall Kaspersky and recheck, it's not absolutely clear from your comments?  
If you did not, i would certainly recommend uninstalling it as first suggested by rpggamergirl, it can always be reinstalled if there's no improvement.

You may also want to have a look at your Firewall settings.
