What makes you think you have malware?I think I might have some virus or malware and I'd like to scan my Mac but I'm new to OSX so I don't know any free scanners that are reliable. Any help would be greatly appreciated. Thanks in advance!
Unless you've been installing pirated software or careless about entering your admin password, your chances of having malware on your Mac are extremely slim. There are many legitimate reasons why something could pop up, without malware being involved. Unless you know what the popup is, it's difficult to know for sure.I think I have something because every now and then something pops up on my desktop but it pops up so quick I can't even see what it is...I don't know if its part of a program I have installed (I was thinking MS Outlook) but who knows...id rather scan and be safe than have something and do nothing about it.
I'm not surprised. As I said, malware is not your problem. I don't see anything running that would contribute significantly to slow performance. However, you've got some page outs showing in your System Memory tab, which could indicate a need for more RAM. You have 2GB, which is pretty low for many users, especially running Lion. If the computer you're using is the MBA in your signature, you're stuck with the RAM you have, so you'll have to take some steps to get the most out of the resources you have. This may help:Also, the scan came back negative for any malware/virus'.
As I said, you're stuck with the RAM you have. Go through the performance tips. That should help.I haven't restarted in a while, however, I have a MacBook Air 2011 and was under the impression that I could not add RAM...so I guess I am stuck with the 2GB (unless you tell me different.) I really appreciate your help at least I know that nothing is wrong with my Mac which I absolutely LOVE!
There's no way your computer can remain connected to WiFi when it's in sleep mode. You just have to be patient to wait a few seconds after waking, so it can reconnect.Another question: Is there a way to stop OSX from turning off my Wi-Fi when my computer goes to sleep or whatever it does after like 10 minutes. When it turns back on from sleep the wi-fi has to reconnect and though it only takes a few seconds id prefer it to be connected at all times.

- Launch Activity Monitor
- Change "My Processes" at the top to "All Processes"
- Click on the CPU column heading once or twice, so the arrow points downward (highest values on top).
- Click on the System Memory tab at the bottom.
- Take a screen shot of the whole Activity Monitor window, then scroll down to see the rest of the list, take another screen shot
- Post your screenshots.
Here you go, hope I did it right. Also, the scan came back negative for any malware/virus'.
I recommend avoiding Sophos, as it can actually increase a Mac's vulnerability, as described here and here. 3rd party antivirus apps are not needed to keep a Mac malware-free, as long as the user practices safe computing, as described in the following link. ClamXav (which is free) is one of the best choices, since it isn't a resource hog, detects both Mac and Windows malware and doesn't run with elevated privileges.I use Sophos it's great it blocks pages that have threats to your mac and protects your mac really well and there's also another one called avast!
What about the akamaihd malware? Does it count as infecting the OS or the browsers? Would Noscript for Firefox block it?
No antivirus app has a 100% detection rate, including ClamXav. That's one more reason not to put your faith in an antivirus app to protect you, but rely instead on responsible computing to avoid malware.
