My computer has been slow since upgrading to AVG 8, but it has become significantly slower in the past few weeks. Symptoms are applications slow to open, IE slow to start & open new windows, IE sometimes doesn't open in a new window at all. I have not, to my knowledge, downloaded any programs recently, but AVG has detected some viruses, presumably blocking them. I am not aware of any symtpoms that might indicate a virus or spyware other than the computer is very slow.

I periodically reboot in an attempt to speed up performance and also run ATF Cleaner to remove any affecting files.

The slowness does not necessarily appear to be caused by CPU usage, but rather by disk I/O.

Here are details of the O/S and virus/spyware applications I have running:
- Windows XP 5.1 SP3
- AVG 8.5.430 Virus DB 270.14.116/2580
- Spy Sweeper 6.1.0.145
- SuperAntiSpyware 4.32.1000
- Spybot - Search & Destroy 1.6.2 (with Tea Timer)

Hopefully, something can help to improve performance.

Hello and welcome to Bleeping Computer. My name is Computer Pro and I will be helping you with your issues.

Please subscribe to your topic so that you will be notified as soon as I post a reply, instead of you having to check the topic all of the time. This will allow you to get an email notification when I reply.

To subscribe, go to your topic, and at the top right hand corner by your first post, click the Options button and then click Track this topic. Then bullet the immediate notification bubble. Finally, press submit.



Lets take a look with Malwarebytes

Please download Malwarebytes' Anti-Malware from here:
Malwarebytes
Please rename the file BEFORE downloading to zztoy.exe instead of mbam-setup.exe

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

Double Click zztoy.exe to install the application.
* Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select "Perform Full Scan", then click Scan.
* The scan may take some time to finish,so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy&Paste the entire MBAM report (even if it does not find anything) in your next reply

Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process, if asked to restart the computer, please do so immediately.


If Malwarebytes won't install or run

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.

I updated SAS to Core Database Version 4412. The complete scan quarantined and removed 10 Adware Tracking Cookies.
