I keep getting pop up adds and getting my files switched around out of order. I noticed the c5zedo going back to its web address on several long page downloads on the bottom left of my page. I tried using my system restore but it won’t let me restore to an earlier time. It’s disabled my Avast Pro I just bought a few months ago. I hope not to lose my picture files more than anything. What to do? Can any free program remove this crap? I have a little money in my PayPal. Can any site scan and remove the virus and repair my windows XP SP3?

System restore is not the way to remove an infection. but there is hope… post in the virus removal topic here at this forum http://forum.avast.com/index.php?board=4.0 . a member named “essexboy” is an expert at stuff like this.
in the meantime, you can try a scan with malwarebytes http://www.malwarebytes.org/
its free, just decline the trial after installation. be sure not to delete your scan log, as essexboy may need that info. good luck!

If there is no response at the “virus/worms” section of Avast forum, you should not wait specifically for essexboy (he is not reachable until the 8th or 9th of this month), you could try for example http://www.geekstogo.com/forum/, where essexboy himself and many others are active and know about “disinfection”.

Unfortunately essexboy, who normally covers these analysis and specialist malware removal tasks is on holiday. There a couple of others who have experience of the analysis of the OTL logs, but they aren’t as frequently on-line as essexboy is/was.
Essexboy is on holiday and will be away from his system 28th September to 6th October. It may take him a little while after that to aclimatise ;D
In the meantime, you could go to Geekstogo. Before posting read this topic, http://www.geekstogo.com/forum/topic/2852-malware-and-spyware-cleaning-guide/, include in the first post a description of the problem, the OTL scan logs and the aswMBR log. That should get a quick response.
For information on and a download location for aswMBR.exe read this topic, http://forum.avast.com/index.php?topic=53253.0.
