Just curious, this question is for the MAC Wizards.
One of my macs is used by at least 4 employees, I have little control over what they look at and what they do.
I was alerted that the mac would not longer go online and they were having a hard time getting the MAC to see the printer.
So, I took a look, would not see the DSL Modem. I tried reconfiguring network/PPP and all. No luck. Dead issue. Then I then ran permissions and it found a bunch of stuff wrong and "fixed" that. Still no Internet. Then went back to Scan Disk and it gave me some kind of fatal error ( can't remember exact Red Message).
I ran Onyx and did a "reasonable" cleaning. It found issues when it ran system permissions and such. No detectable improvements resulted.
So, I tried to reboot with system disk ( OSX 10.4) no luck. The CD/DVD would not work at all???? Unplugged it, I opened up machine and cleaned out dust and such. Still no luck. I then removed CD/DVD drive and cleaned it and put it back in. Still did not work. I restarted the comp and removed the drives data bus and plugged it back in. It started working? Ok, rebooted off system disk. Ran disk utility, found all sorts of problems. MANY problems with DVD permissions and such as well as a host of others.
I restarted comp and it took a long time to load up OSX...... then it failed to see the CD/DVD drive again?
I then restarted system off another clean disk partition and looked at the infected system with Disk Utility and once again permission problems...ones with CD/DVD... "Fixed them"....
Restarted from the "bad" system, things looked good... went to System Pref - Network and tried to get connected. I started getting a message that the Network connection has been changed by another application. I would not allow me to make any changes? Restarted from clean partition and got online.
I ran onyx again - ALL. Got internet back on the "infected partition"!. So I installed CLAMxav onto the "infected" system. I started having issues with it when I tried to open it and it would shut "it" off. Ok, I am thinking virus. No matter what, I could not run this program. I rebooted with system disk and ran utilities, fixed "same" issues. I then installed CLAM(ran updates) on the clean disk partition and ran a scan on the infected partition. NOTHING that looked liked a problem was detected. Now I am running MacScan and so far nothing.
Am I just retarded? I have lots of MAC experience and have many machines but rarely do I see viruses. Back in the days of 8.6 - 9.2 I got the Boo Hoo Virus, a few trojans...
I was just wondering if the experts have any ideas... I feel as if I have/had a virus.... but time will tell. Any thoughts?
