Did you at least put it on a laptop cooling pad?
Also Z.lob can do untold damage. Maybe you should try a total system restoration and think over how Z.lob got onto the machine. Sometimes I find it on machines that the owner uses P2P apps and downloads games.
Alright, I did a virus scan this morning and AVG found a virus in Download(er)Z.lob. AVG deleted it and stuff. I downloaded a game and played it for a good couple of minutes and it started to have trouble. Well, I quit the game and tried to get on the Internet. Well, when I did, it said it could not open. [Say what?] I tried other programs like Microsoft Word. It said it couldn't open. [There goes my story writing.] I tried my trusty ole' System Restore, it couldn't open. [Nooooo!] It said a file was missing from its library. [Uh oh..] Well, I got to open Windows Live Messanger [Woo Hoo!], then.. whenever I did a voice clip and Messanger froze up, and exited. I logged back into it and tried the voice clip again, it did the same thing. Then, I ran a virus scan by AVG and after a couple of files, my computer went [Bloop] and shut itself off. I tried to turn it back on.. it seemed to boot up, but the screeen stayed black and the button stayed green. I've tried the USB, F2, Esc, F12, and all other things in my manual. Please help ><. I have an Acer Aspire 5520- 5912.
