Update Adobe Reader

You can download it from https://www.techspot.com/downloads/2083-adobe-reader-dc.html
After installing the latest Adobe Reader, uninstall all previous versions.
Note. If you already have Adobe Photoshop® Album Starter Edition installed or do not wish to have it installed UNcheck the box which says Also Download Adobe Photoshop® Album Starter Edition.

Alternatively, you can uninstall Adobe Reader (33.5 MB), download and install Foxit PDF Reader(3.5MB) from HERE.
It's a much smaller file to download and uses a lot less resources than Adobe Reader.
Note: When installing FoxitReader, make sure to UN-check any pre-checked toolbar, or other garbage.
On this page:

make sure, you have both boxes UN-checked AND (important!) click on Decline button

The anti virus just finished this morning. No threats founds. It must have scanned my external hardrive too. 250 G.

 

[msta999]

I downloaded Adobe 9.4 and installed it, went to uninstall 9.1 and could no longer find it.

Your computer is clean

1. We need to reset system restore to prevent your computer from being accidentally reinfected by using some old restore point(s). We'll create fresh, clean restore point, using following OTL script:

Run OTL

• Under the Custom Scans/Fixes box at the bottom, paste in the following:

:OTL
:Commands
[purity]
[emptytemp]
[EMPTYFLASH]
[CLEARALLRESTOREPOINTS]
[Reboot]

• Then click the Run Fix button at the top
• Let the program run unhindered, reboot the PC when it is done
• Post resulting log.

2. Now, we'll remove all tools, we used during our cleaning process

Clean up with OTL:

• Double-click OTL.exe to start the program.
• Close all other programs apart from OTL as this step will require a reboot
• On the OTL main screen, press the CLEANUP button
• Say Yes to the prompt and then allow the program to reboot your computer.

If you still have any tools or logs leftover on your computer you can go ahead and delete those off of your computer now.

3. Make sure, Windows Updates are current.

4. If any Trojan was listed among your infection(s), make sure, you change all of your on-line important passwords (bank account(s), secured web sites, etc.) immediately!

5. Download, and install WOT (Web OF Trust): http://www.mywot.com/. It'll warn you (in most cases) about dangerous web sites.

6. Run Malwarebytes "Quick scan" once in a while to assure safety of your computer.

7. Run Temporary File Cleaner (TFC) weekly.

8. Download and install Secunia Personal Software Inspector (PSI): https://www.techspot.com/downloads/4898-secunia-personal-software-inspector-psi.html. The Secunia PSI is a FREE security tool designed to detect vulnerable and out-dated programs and plug-ins which expose your PC to attacks. Run it weekly.

9. (optional) If you want to keep all your programs up to date, download and install FileHippo Update Checker.
The Update Checker will scan your computer for installed software, check the versions and then send this information to FileHippo.com to see if there are any newer releases.

10. Run defrag at your convenience.

11. Read How did I get infected?, With steps so it does not happen again!: http://www.bleepingcomputer.com/forums/topic2520.html

12. Please, let me know, how your computer is doing.

12. Please, let me know, how your computer is doing.

Whenever you're ready....

 

[msta999]

Thanks again Broni,

I am going to bookmark this page so I can do the mainenance now and then. Seems to be a lot better. the only thing I see is yahoo mail takes for ever to load, but that has been since they changed the look of thier email. I still have to change some pass words, but other than that, I believe I got everything.

Thanks again.

Were you able to see anything in the data I sent you, that looked like a problem?

 

[Broni]

Well, your main issue was infected MBR, then we removed couple of items with OTL.
That's about it.

In any case, I'm glad to see your computer happy again

Good luck and stay safe

 

[msta999]

Back at ya!

Thanks again.

 

[Broni]

Sure thing

 

[msta999]

Broni,

Scrolling up and down a page is real jerky. Is there something that can be done about that? It started doing this a couple weeks ago.

 

[Broni]

In a browser?
Which one?

 

[msta999]

Internet Explorer

 

[Broni]

Close IE.
Go Start>All Programs>Accessories>System Tools, and click on Internet Explorer (no add-ons). Same problem?

 

[msta999]

Yes, still the same.

 

[Broni]

See, if same thing happens in Safe Mode with Networking.

 

[msta999]

Do I just reboot, in safe mode?

 

[msta999]

go to safe mode, by rebooting?

 

[Broni]

Yes, but Safe Mode with Networking. In pure Safe Mode, you won't have internet connection

 

[msta999]

Yes! Everything is much faster.

 

[Broni]

I suspect, it may be Kaspersky slowing you down.

 

[msta999]

Ok, thanks, as long as I know what it is. I just checked googlecrome and it is fater than IE.

 

[Broni]

You're welcome

A few weeks ago, I changed my printer from one computer to this computer (about the same time I noticed things getting slow) and I uninstalled the software from the computer the other day. Today my daughter said the computer is a lot faster now. I'm thinking that may be my problem with this computer. Any way to check to see if the printer software is my problem without uninstalling it?
