You have multiple problems!!!First is you have antivirus software installed, this is totally unnecessary. There are no viruses for OS X, however there is a small amount of malware out there that can be avoided by using some common sense! Follow the developers instructions for uninstalling the Symantec software!!The common sense:Never download from a torrent site.IF you get a popup, ad, e-mail or phone call advising the computer has been compromised, these are SCAMS!!!!Keep OS X up-to date!Second issue, running Yosemite 10.10.x with 2GB of RAM is insufficient. Upgrade your 2008 to 6GB (the maximum amount), purchase RAM from either Crucial or OWC at www.macsales.com

Ditch ALL Googlewares. They are ALL a serious resource hogs on the OS X system.The additional benefit is that you&#x27;ll stop Google from mining your data when you surf the webhttps://support.google.com/chrome/answer/95319?hl&#x3D;enIf you do not like Apple&#x27;s Safari web browser, download, install and try Mozilla FireFox, instead.http://www.mozilla.org/en-US/firefoxThe current, up-to-date version of FireFox is fully compatible with OS X and is regularly updated by the great developers of the Mozilla group.I have, also, stopped using the Google search engine regularly (due to Google&#x27;s privacy policies or lack thereof) and I now use DuckDuckGo as my default search engine.Trusteer Rapport is another troublesome application on OS X.

You have waaaay too many login/startup items.You need to pare this down to less than 6 items.Add or remove automatic itemsChoose Apple menu &gt; System Preferences, then click Users &amp; Groups.Select your user account, then click Login Items.Do one of the following:Click Add ➕ below the list on the right, select an app, document, folder, or disk, then click Add.If you don’t want an item’s windows to be visible after login, select Hide. (Hide does not apply to servers, which always appear in the Finder after login.)Select the name of the item you want to prevent from opening automatically, then click Delete ➖ below the list on the right.
