Hi,

I had to recently uninstall my AV and when I try to reinstall it, it does install but when I click on the icon nothing happens. In addition to that, my internet service is gone into super slow motion too. Taking quite a while to open pages etc. I am also not able to run Malware antimalware, HJT and also unable to use online scanner.

Please advice.

Which AV. Some, eg, Norton, AVG, require a special uninstaller tool to be run. The slowness is most likely due to a confused AV installation - all file activity, traffic is monitored by the AV.

see this thread...
similar problem

i have the same problem, its resolved to some extent but i am going to be doing all this soon....

..or perhaps you installed the AV into an infected system, or perhaps you have become infected with some malware which your AV does not detect.
Tell which AV you uninstalled.

My apologies, I have Kaspersky Internet Security 2009

Good-oh. You might try running the correct removal tool from this site, and then attempt to reinstall KIS.

Good luck. And please come back if that does not solve your problem.

Hi,

I ran the uninstaller. But it does not detect that KIS is installed. This is peculiar because my Windows Security Alert tells me that the Antivirus and the firewall are switched off.

So reinstalled and then used the remover to uninstall the software only to get the same description from the Windows Security Alert. Also I noticed that there are no restore points available for System Restore!

Okay. It does look like a few keys in registry are not being cleaned, and Windows Security is picking up on them. More worrying is the inability to run anti-malware scans, loss of restore points. Let's try a couple in safe mode as an initial check:
==Please download Malwarebytes' Anti-Malware
from: http://www.majorgeeks.com/Malwarebyt...are_d5756.html
or: http://www.besttechie.net/tools/mbam-setup.exe
=Dclick that file, mbam-setup.exe, to install the application,
-ensure that it is set to update and start, else start it via the icon, and UPDATE it.
Select "Perform QUICK Scan", then click Scan; the application will guide you through the remaining steps.
ENSURE that EVERYTHING found has a CHECKMARK against it, then click Remove Selected.
If malware has been found [and removed] MBAM will automatically produce a log for you... do not click the Save Logfile button.
When it completes examine the log: if some files are listed as Delete on Reboot then restart your machine before continuing.
Post the Notepad log [it is also saved under Logs tab in MBAM].

MBAM can still be installed and updated without a connection. Using a flashdrive on another system, download & save the installer file from http://www.majorgeeks.com/Malwarebyt...are_d5756.html, then dl the latest updates file: http://www.gt500.org/malwarebytes/database.jsp , both to a thumbdrive.
Run the installer, when it completes uncheck the Launch and Update boxes to finish. Next, dclick the mbam-rules.exe file, it will install into MBAM.
Start MBAM via the icon and ...

==download hijackthis: http://www.majorgeeks.com/download5554.html
-copy it to a new FOLDER placed either alongside your program files or on your desktop and then... rename hijackthis.exe to imabunny.exe
-in that folder start HijackThis by dclicking the .exe
-CLOSE ALL OTHER APPLICATIONS and any open windows including the explorer window containing HijackThis.
-click the Scan and Save a Logfile button. Post the log here.

Tried the steps, but the application do not execute at all. When I click on the icons to run the application there is no changes at all except for the hourglass appearing for a couple of seconds.

I had the Task Manager up when I was trying to run these applications but on clicking them there is no response in the Task Manager, no sign of a new process at all.

hey
try running dr web as asked in that link i posted once...
may be it'll help
