Started having problems opening and saving PDF files

marsmimar · 22 Oct 2011

Adding to other suggestions to check for malware, I'd also recommend Malwarebytes Free. Update the database and run a full scan. It seems to catch things others miss.

Malwarebytes : Malwarebytes Anti-Malware is a free download that removes viruses and malware from your computer

You may have somehow lost ownership of your files preventing them from being opened.

Take Ownership Shortcut

If ownership is not a problem you might consider using Adobe's latest and greatest PDF program called Adobe Reader X. Or another freebie called Nitro PDF Reader.

It is possible one or more of the PDFs you tried to open were tainted with some badwares as well. You can try a scan without booting into Windows with https://www.sevenforums.com/tutorials...ml#post1424613

I aslo use Foxit Reader because Adobe reader is very big, bloated and phones home too much.

I ran a full virus scan and a full MalWare scan when the problem started and the found no problems. I try and stay away from any suspect sites as much as I can. At this time I use AVG and Zone Alarm for my security.

I downloaded Adobe 10.1.1 at work and brought it home and installed it but that did not change anything. I can open PDF's on my computer but I can't open then from email or from the web and now I can't download any programs at all from the web.

I did change my phone system from AT&T to Cox (not sure if my problem started at this time). The phone modem hooks into the internet but not into the computer so I don't think that could be a problem, but maybe it is.

I also have a router that my son installed for me (so he could use it when he was home) but I have had that for a few months and this problem just started.

Have you tried a different browser?
It could be that FF settings got hosed or something got corrupted.

Didn't think of that, so I tried IE and went to download.com and tried to download Foxit and then Adobe Reader and both times I was told that they has a virus and they were deleted.

I then ran a complete scan using Microsoft Malicious Software Removal Tool and it found no problems. I have something going on, but I just don't know what.

When I tried to download the MS Standalone, IE said it had a virus and deleted it. I will download it at work and bring it home.

You have a serious problem, IE has no way to detect viruses. Get the stand alone soon and run it as in the tutorial. It sounds like you have a rootkit, worm or trojan.

EDIT:
Another member, Karlsnooks sugested:
Safety Scanner, Microsoft Safety Scanner - Antivirus | Remove Spyware, Malware, Viruses Free, is free, downloadable, provides on-demand scanning and helps remove viruses, spyware, and other malicious software. It works with your existing antivirus software.

Thank you Britton30, I used the Stand Alone program and it found - Trojandownloader: Java/openconnection.oi. It also cleaned my computer and everything seems to be back to normal. - EDIT - I spoke to soon, I still can't download any programs. I tried to download Microsoft Safety Scannner and that was a no go! And the problems continue.

Here is some info on the trojan: http://www.microsoft.com/security/po...nConnection.OI

Near the page bottom is a link to remove Java, which I highly recommend, this trojan uses a Java exploit to run.

It has also been seen by another member who cleaned it with MS Security Essentials (link below my sig) and the stand alone sweeper: MS security essentials an windows defender

Below my sig is a link to Super AntiSpyware, try to download and run it as well after updating it. You may have to do this from another PC again.

Also in my previous post try the Microsoft Safety Scanner at work if possible. This is a tough trojan.
