I'm running Windows Vista on a Dell XPS 410 desktop. I have 2000 mb of RAM installed.
What happens is that after going to some legitimate sites, my system occasionally slows down afterwards and stays slow. I find that rebooting resolves this and sometimes using Ccleaner resolves this.
This system can handle 4000 MB of memory and I suspect I should add that memory but looking at Task Manager, the performance seems ok even when the system slows down.
I assume using Ccleaner gets rid of some of the junk that is added when surfing the Internet but I was wondering if I need to do more to keep the system clean.
I do notice that when the McAfee Anti Virus program is doing a scan, the system also slows down and that suggests I may need more memory.
I do not have any viruses or malware indicated on the McAffee scans.
I suspect that as this computer is about 5 years old, websites have grown in size and require more memory today when surfing today then when the computer was new.
I'm also wondering if upgrading to Windows 7 would help but I suspect the operating system isn't the issue as the system works normally until I go to certain sites that seem to be legitimate NY Yankee sites (I don't want to run Windows 8.1 and would rather wait until June when Windows 9 comes out if I don't upgrade to Windows 7).
